1st Hollow Form on New Powermatic 3520C Lathe

1st Hollow Form on New Powermatic 3520C Lathe Photo: 1st Hollow Form on New Powermatic 3520C

The second thing I turned on my new Powermatic 3520C Lathe was a nice cherry hollow form.

Here is the hollow form, all done.

I put a high gloss finish on this piece. Gloss sells. But, it made getting a good photo a real pain. To many reflections.

7-1/2" diameter. 7-3/4" tall. Cherry wood.

The blank was a little out of balance. But, it did NOT give me any trouble. My new Powermatic 3520C lathe, handled it, no problem.

Note: Full disclosure. I also have a big VB36 lathe that I use for most of my hollow form turning. Turning this hollow form on my new Powermatic 3520C was a "one off" kind of thing. I did it, to check out the new lathe and write this blog entry.

Photo: Me and My New Powermatic 3520C Lathe Me and My New Powermatic 3520C Lathe

Here I am all suited up and all ready to go. Standing in front of my new Powermatic 3520C Lathe.

For more info about my new lathe see "My New Powermatic 3530C Lathe Verses My Old Powermatic 3520B" blog entry.

I really like the color of the Powermatic Turning Smock that I am wearing. Over time I have owned a lot of smocks. I have found that the AAW Turning Smock is the best design for me. It is light weight, well ventilated, sheds wood savings easily and comes out of the washing machine, looking like new. However, I really hate the blue and other dark colors! The PM smock is the same design and fabric. Just a lot better color.

Well, there is one difference / problem. The PM smock zips on the left. Most men's clothes in the US and the AAW smock zip on the right. I had to purchase my own PM smock on the web. The $50 price is the same as the AAW smock. Shipping is not cheap.

Photo: Cherry Blank Between Centers Cherry Blank Between Centers

Here is the cherry wood log blank that I started with. My silver 1 foot ruler is on top.

The blank was roughly 10" long. The blank was a bit oval and thus the diameter was difficult to measure. Sort of 9" diameter.

You can also see that the blank had a big knot in the side from a branch. I really like the interesting grain pattern this added to the finished piece. See first photo above. However, it can make the piece hard to hollow when your hollowing tool bounces around due to the hard spot created by the grain around the knot.

You can also see I am driving the blank with my big gold drive center from Stubby Lathe USA. They are no longer available. If I wanted to purchase one today, I would have to go with a Elio-DR Safe Drive or Big Bite Chuck Spur. See my "Best Drive Center" blog entry.

You can also see that the chain saw cut on the end of the log was a bit off. It is not very square. This and the knot are going to make the blank out of balance when I turn the lathe on. See next photo.

Photo: Powermatic 3520C Stability Video Powermatic 3520C Stability Video

I was pleasantly surprised to find my new lathe was able to spin this sort of out of balance log at 500 rpm. Almost not problem. See the video at right. Take note of the glass of water on the bed of the lathe.

The log was sort of out of balance due to the NON square cut on the end of the log and the bit knot. See previous photo.

I strongly believe that all lathes can be vastly improved by adding 200+ lbs of weight to a shelf on the bottom of lathe. This makes them run a lot more stable. In this video I have NOT added any weight yet. Thus I was not expecting it to be this stable.

I will be adding a shelf with 200+ lbs of weight to this lathe. I have already done it. Stay turned for a future blog entry.

Note: One data point does not really prove anything. Your mileage may vary! I am sure my mileage will vary. Maybe the piece is not really all that far out of balance.

This photo shows how I moved the new movable control box for the lathe. While I was truing up the end of the log. I am getting ready to mount a face plate.

This photo shows the end of the log after I trued it up. I am getting ready to mount it on a face plate.

Photo: Oneway Banjo Oneway Banjo

The new PM banjo that comes with the new PM 3520C is better than the old PM 3520B banjo. But, I still really do not like the offset design of the PM banjo.

I strongly prefer the NON offset design of the Oneway banjo shown in this photo. It allows me to get the banjo in there with out having to crank the quill in the tailstock way out. For more info see Oneway Banjo section of "My New Powermatic 3530C Lathe Verses My Old Powermatic 3520B" blog entry.

The stock PM tool rest is ok. But, it is to tall to fit in a Oneway banjo. PM make their banjos extra low to accommodate there tool rest.

The tool rest you see here is the one I prefer. It was custom made for me. It is very similar to the one I really love on my big VB36 lathe. I like my tool rests to be at least a 1/2" wide and almost flat on top so I can feel when my bowl gouge is straight across on top of the rest. I also prefer really beefy and strong tool rests. So there is absolutely no flex or vibration out near the end of the rest. Thus I like my rests to be made out of a 1/2" thick by 2" wide STEEL bar. With a 1" post that slopes off at 45 degrees, 3/4" of an inch below the top of the rest. With a really big and beefy weld between the post and steel bar. I like to have 4", 9" and 14" long tool rests for each lathe.

I do NOT like the Oneway tool rests or the Robust tools rests with the silly little round bar on top. "To each is own!"

Photo: Attach Oneway Face Plate Attach Oneway Face Plate

This photo shows me attaching a Oneway face plate after truing up the end of the blank.

I strongly prefer to use face plates rather than chucks. With proper screws they are the most secure way to mount something on the lathe.

I like to use #14 stainless steel sheet metal screws. I prefer square drive. item #93945A071 for 1.5 inch long screws. I can easily drive the screws in with a Cordless Impact Driver. You can see my Makita impact driver in the background.

Photo: The Powermatic Face Plate The Powermatic Face Plate

This photos shows the 3" PM face plate that comes with a PM 3520C lathe, on the left. A Oneway 4" face plate is on the right.

The thin little crappy cast iron face plates that come with most modern lathes, are worthless. They will crack almost instantly if you really screw them down with decent screws. The PM face plate is thick and beefy. Thus it is ok. A big step above what comes with most lathes. I some times use it. But, for this size log the bigger 4" Oneway face plate is a better choice.

Photo: Blank on Face plate Blank on Face plate

Here is the blank mounted on a face plate. Ready to turn.

I ALWAYS use the tailstock when possible for safety. It takes like 20 seconds to put the tailstock in place. Going to the hospital to get stitched up takes hours!

Photo: Round Blank Round Blank

Here is what the blank looked like after I roughed it down to round.

I like to use a John Jordan 5/8" V Bowl Gouge to rough turn things. John's V shape is deep and wide open at the top. It just seems to work better than anything else I have tried. It cuts really fast and consistently throws a chip that I can easily aim to land directly in my trash can.

For more info see "My Modern Woodturning Tool Set" blog entry.

Photo: Rough Shape Rough Shape

Here is what the blank looked like after I roughed in a shape.

I always start on the left. I remove a chuck of wood with a 45 degree angle cut this is big enough to get me back above the screws. This way I known, latter when I turn my finial shape, the the bottom will NOT end up in the screws. Then I extend the 45 degree cut a little more to the right when my bottom shape will allow it.

I work on the right, after I get the left roughed in. I removed a chunk of wood on the right with a 45 degree angle cut when my top shape will allow it. Then I true up the top of the blank and make it a little concave.

I usually do this step using my Jordan 5/8" V Bowl Gouge.

Photo: Finished Outside Shape Finished Outside Shape

Here is the finished outside shape.

I find that cutting the shape using the "wing" on a 5/8" Ellsworth Bowl Gouge works best. I cut the rim detail using my 1/2" Hosaluk Double Bevel Detail Gouge.

In the past, I would then shear scrape with my Ellsworth Bowl Gouge or an Al Stirt style shear scrapper. In really green wood, I have progressed to the point where I can now cut the outside shape cleaner using my 1/2" Hosaluk Double Bevel Detail Gouge. You can see in the photo that the surface is pretty good. I have NOT sanded it yet.

Photo: 7-1/2 7-1/2″ Diameter

The finished piece ended up being roughly 7-1/2" in diameter.

You can clearly see in this photo that the pith ended up being off center. Some people would be upset by this. I have decided I really don't care. I just don't want the pith IN the rim. Anywhere else in the top, where it will get cut OUT, when I hollow is OK.

The pith regardless of where it is (on center or off center) in the bottom will always cause cracks. It will also, always cause some distortion in the rim. I don't really care. I have learned to love the distortion it adds. It makes each piece unique and more artistic.

Photo: 7-3/4 7-3/4″ Tall

Here is a nice side profile shot. The finished piece ended up being roughly 7-3/4" tall.

Photo: To Drill or Not To Drill To Drill or Not To Drill

I always drill out the center on my pieces using a 1" diameter morse tapper shank drill. The drill mounts directly in the tail stock via the morse taper shank.

Drilling out the center, establishes my inside bottom depth and makes the hollowing process a lot easier and faster.

The funny copper thing attached to the drill is my laser guide. It makes drilling the hole to the correct depth, fast and easy. A red laser points down from the green tip. It shows precisely where the tip of the drill is inside of the blank. You can not see the red laser beam in the photo. But you can see the red dot from the laser on the very tip of the drill if you look closely.

Photo: Hollowing Rig with TV Hollowing Rig with TV

This photo shows my Hollowing Rid with TV Camera and TV Screen.

I ALWAYS hollow with the lathe running in reverse. Thus the cutter head in this photo is set up to cut on the right side.

I use a Trent Bosch Hollowing Stabilizer rig with a Rolly Munro cutter head.

I really love the Bosch Stabilizer. Because, it takes all the stress out of holding the hollowing tool level and it does not let the hollowing tool twist or roll over. However, It DOES NOT restrict my movement. I still have a tool handle, like on my bowl gouges and free hand hollowing tools. I can keep that tool handle up against my body, unlock my knees and use my body to hollow out a nice shape. Just like, I do when turning a bowl. Just like, I have practiced over and over again, while learning to turn a bowl. I don't like any of the other hollowing rigs (Jamieson, Elbo, Monster, etc) because they restrict my movement and I have to maneuver the tools using just my arms. I can't use my body.

I use a "Munro Hollower II" cutter head with a carbide cutter. I purchase the cutter head from Steve Sinner and supply my own custom 3/4" steel bar. I like the older "Munro Hollower II" rather than the new "Munro Wundercutt 10 Hollower". The new one does not work as well for this application.

I have created my own TV system. Finding the right camera is a HUGE problem. Thus I recommend people purchase the Trent Bosch Visualizer system. It is not cheap at $650. However, making your own system may approach this cost after a few miss steps, etc.

For more info on my hollowing rig click here.

Photo:  TV System in Action TV System in Action

This photo shows the TV system in action. In the lower half, you can see the Munro cutter head is just starting to hollow out the top of the piece. Pointed to by magenta arrow in photo.

On the TV you can see part of the cutter head is exposed. The other part is represented by the blue line on screen. Pointed to by the blue arrow on photo.

The red line is my target wall thickness. Pointed to by the red arrow in photo. The red line is 1/4" away from blue line in real life down on the tool rest. Up on the TV monitor it is more like 1/2" due to magnification of TV camera and monitor.

The green arrow on photo points to the tiny TV camera.

My TV camera works best in low light. So I normally shut most of the overhead lights off. The bright light on the piece in photo is for the photo.

I draw the red and blue lines on the TV screen with white board dry erase markers. They did not show up well in my photo with the bright light for photo. Thus I enhanced them (redrew them) in Photoshop. I also added the red, blue, green and magenta arrows in Photoshop.

Photo: Cutter Head on TV Cutter Head on TV

This photo shows the completely hidden cutter head represented by blue and red lines on TV screen. The blue line is the outline of the cutter head. The red line is my target wall thickness.

In the real world, after I draw the red and blue lines on the TV screen they ALWAYS move in sync with the cutter head. Because the TV camera moves in sync with the cutter head. i.e. the TV camera is always directly over and pointing down at the cutter head. Back up 2 photos to see TV camera mount. For more info see "Trent Bosch Visualizer" on YouTube.

In this case, I want my finial wall thickness to be roughly 3/16". Thus I have drawn the red line so it is 1/4" away from blue line. I will rough the wall thickness to 1/4" by going to the outside of the red line. Then. I will come back with a finish cut to the inside of the red line. The red line on screen is roughly 1/16" of wall thickness wide. Thus I will end up with a 3/16" finial wall thickness.

Note: I enhanced the red and blue lines in this photo in Photoshop.

Photo: Inside of Hollow Form Inside of Hollow Form

This photo shows the inside of the hollow form after I have hollowed it out partially. The rim is pretty much finished. The side walls are still a little thick. The depth hole, I drilled in the center is still visible.

Photo: Let There be Light Let There be Light

In this photo I am double checking the wall thickness with a $10 Jansjo LED light from Ikea. The really bright part of the piece is the white sap wood on the Cherry log. The darker part is the brown heart wood. The WET sap wood always transmits more light than the heart wood.

Everything looks good here. I am done hollowing.

This photo also shows my normal almost dark lighting in the room. You can see on the TV screen that my TV camera is real happy with this level of light.

Photo: Ready to Sand Ready to Sand

This photo shows the bottom cleaned up. Ready to be sanded and then parted

I used a bowl gouge to start finishing up the bottom. I removed any extra wood I left earlier to support the piece while hollowing. Then I sand.

Photo: Sanded and Buffed Sanded and Buffed

This photo shows the piece after it has been sanded to 220 then buffed with synthetic steel wood and a towel.

I started with a green (aka soaking wet) log. But, in this case, it was not to wet. Thus I got away with sanding and buffing it on the lathe.

First I sand with red 80 and 120 grit Sia Soft cloth & foam back sand paper from "Vince's Wooden Wonders". I use 9 or 10 3" x 4" pieces of Sia Soft. At first, each piece jams very quickly with a short of brown mush because the wood is wet. You get brown mush rather than saw dust. However, friction dries the SURFACE of the wood as you go. Eventually the sand paper comes away almost clean.

Then, I switch to 3" round Mirka AutoNet Mesh sanding disks from "Buff Daddy". I sand thru 120, 180 and then 220 grits. I never go beyond 220. I buff beyond 220! AutoNet is very similar to AbraNet made by Mirka. AutoNet is cheaper. Otherwise I can't tell the difference.

Then, I buff with Carl Ford Medium and Fine synthetic steel wool (nylon mesh pads, scotch brite pads, etc). I prefer the Silicon Carbide stuff that is for use on metals. I use it on wood. No problem. I get it from McMaster Carr, item # 4659A17 and 4659A18. Mcmaster calls it ulta, super dupper, extra fine or something crazy like that. I just call it medium and fine.

Finally, I buff with a blue Surgical Cotton Huck Towel from Amazon.

Photo: It Looks Good! It Looks Good!

Another photo of the piece after it has been sanded and buffed.

The circular grain on the right is the knot from the branch. See photos at beginning. The white on the left is the sap wood. The brown is the heart wood.

Photo: Jam Chuck Jam Chuck

This photo shows a jam chuck that is the perfect size for my stretch wrap plastic trick. Just a little smaller than the piece. See next photo.

Photo: Stretch Wrapped Stretch Wrapped

This photo shows the piece being held on the jam chuck via stretch wrap.

This will allow me to finish the bottom with out a vacuum chuck. I try to avoid using my vacuum chuck system when the piece is wet green wood. Because, the vacuum sucks the water unevenly out of the piece.

You can purchase stretch wrap in 4" wide rolls from local office supply store.

Photo: Bottom Ready for Sanding Bottom Ready for Sanding

This photo shows the piece after I removed the face plate and cut away the excess wood with a 1/2" bowl gouge. I like to use a 1/2" bowl gouge with an Al Stirt grind to remove most of the wood. I then use my 1/2" Hosaluk Double Bevel Detail Gouge to cut off the last little nib and finish up.

Photo: Bottom Ready For Finish Bottom Ready For Finish

This photos shows the bottom all sanded and buffed. Ready for finish.

Photo: Ready for Finish Ready for Finish

This photo shows the piece all done. Ready for a finish.

Photo: Oh Man Look at that Rust! Oh Man Look at that Rust!

This photo shows why some people waste a ton of money on stupid stainless steels ways for their lathe. They think this is rust. NO WAY! This is not rust.

I was turning a nice green (i.e. wet) cherry log. The sap in a cherry log is a thin brown colored liquid. When you turn a wet cherry log on a lathe the sap comes flying out and lands on the ways. When it drys on the ways it looks like this. Yea, it may look like rust. But, it is not!

You can easily clean this mess off with a little WD40, a chunk of synthetic steel wool, and a paper towel. See next photo.

You have to clean this mess up EVEN if you have stainless steel ways! Yea, that's right! Stainless ways DO NOT stop the mess from happening! You have to clean the ways even if they are stainless. So why waste a ton of money on stainless?

Stainless steel ways cost big bucks. I can purchase a ton of WD40 for a lot less.

Photo: All Cleaned Up All Cleaned Up

This photos shows the ways of the lathe after I cleaned off the brown cherry wood sap. It took like 2 minutes.

1st Plate Bowl on New Powermatic 3520C Lathe

1st Plate Bowl on New Powermatic 3520C Lathe Photo: 1st Plate Bowl on New Powermatic 3520C

The first thing I turned on my new Powermatic 3520C Lathe is what I call a plate bowl. A plate with a little bowl in the center. I like to turn this shape and then use it as a canvas that I can decorate.

Here is the finished plate bowl.

10" diameter. 1-1/2" tall. Maple wood. Lathe and hand carved rings and grooves. Red stain. Gold acrylic paint. Acrylic lacquer finish.

Turning this on my new Powermatic 3520C was as “easy as pie”. No mounting problems. No vibration problems, etc. This piece is small and easy. Thus, I was not expecting any problems.

Note: I am teaching a plate class at the Brookfield Craft Center on Saturday and Sunday, May 5 and 6, 2018. We will be making similar plates or plate bowls in that class.

Photo: My New Powermatic 3520C Lathe My New Powermatic 3520C Lathe

Here is what my new lathe looks like.

For more info see "My New Powermatic 3530C Lathe Verses My Old Powermatic 3520B" blog entry.

Photo: The Blank The Blank

Here is the blank mounted on a screw in my chuck. The blank is a chunk of hard maple wood. Roughly 2" thick by 10-1/2" in diameter.

I just cut the corners off on the band saw. I made absolutely no attempt to make the blank round on the band saw. I have a lathe for making things round!

Here I am getting ready to true up the face of the blank.

You can see here why I do not like the stock Powermatic banjo with its offset tool post design. I have to crank the quill in the tailstock way out to get the offset Powermatic banjo in there. The quill is way to far out for safety in my opinion.

This is why I strongly prefer the NON offset design of Oneway banjos. For more info see Oneway Banjo section of "My New Powermatic 3530C Lathe Verses My Old Powermatic 3520B" blog entry.

Photo: Bottom Roughed Out Bottom Roughed Out

Here I roughed out the bottom of the plate bowl. I am ready to turn the blank around and work on the front.

First I turned the outside round and slightly down hill from the top. The top is on the headstock side. Then, I turned a tenon on the bottom that matches my Oneway Stronghold Chuck. I left the rest of the blank pretty thick so I can cut grooves on the other side. If I made the plate wall thin now, then it would flex to much, when I tried to cut the grooves.

Photo: Top Finished Top Finished

Hind site is always 20/20. I wish I took more photos. I forgot to take some photos of top side trued up. Then another photo of me cutting the bowl.

In this photo, I am getting ready to paint the gold rings. Painting between well defined lines is easy with the lathe running. Thus, I first cut some shallow coves to hold the gold paint and then some V grooves on either side to create well defined lines.

At this point I have NOT thinned out the plate. The bottom is still thick, like in previous photo. I am going to thin it out latter, at the very end.

Power Carve the Radial Grooves

I removed the CHUCK from the lathe. I left the piece in the chuck! Latter, I want to be able to remount the piece and still have it run true.

I laid out the radial lines with a pencil. Then I carved the lines with a V chisel in my Ryobi power carver. After carving, I removed any left over pencil lines and eased over any hard edges with a 3M radial bristle disk.

For more info see my "Power Carving Textures" blog entry.

Unfortunately, from this point on I forgot to take step by step photos.

Stain It Red

I stained the entire top and sides with red alcohol based stain. I forced the stain into all of the rings and grooves.

I let the stain dry for a while. Or, did I let it dry over night? I really don’t remember.

Paint the Gold Rings

After the stain dried. I put the chuck with the piece still mounted in it, back on the lathe. I painted the gold rings that I turned in with gold acrylic paint. With the lathe running slowly. With a 1/4″ round paint brush. I wanted the red stain to show thru the paint a bit, but not to much. Thus I adjusted the thickness / thinness of the paint with some air brush medium.

I then removed the chuck again from lathe.

After the gold paint dried I sealed the entire top surface with a couple of coats of rattle can lacquer.

Paint the Gold Grooves

After sealing, I painted the grooves that I carved in with gold acrylic paint. I used a 1/4″ round paint brush. This was not easy. I had to dork around a lot. Wipe it off some. Paint some on, again. Until I ended up with the paint, just in the groves, with some red showing thru.

I sealed the entire top surface again, after the paint dried, with a couple of coats of rattle can lacquer.

Photo: Steel Wool & Buff Steel Wool & Buff

Here is what the piece looked like when I mounted the chuck back on the lathe. I turned the lathe on and used some synthetic steel wool to remove any dust in the lacquer and buffed it with a soft cloth.

Photo: Turn The Back Turn The Back

I turned the piece around and mounted it on a vacuum chuck. So I could finish the bottom. I thinned out the bottom to match the top. Then I stained it, sealed it, etc.

Here is what the finished bottom looks like. The picture was taken at a slight angle so you can see some of the details.

I really wish I had remembered to take a lot more photos for my blog!

My New Powermatic 3520C Lathe verses my Old Powermatic 3520B Photo: My New Powermatic 3520C Lathe verses my Old Powermatic 3520B

I decided to replace my old Powermatic 3520B Lathe with the new C Model.

Here is my unpacking and set up experience. Plus some comparison of the B and C models.

I purchased the new model C on 2/1/2018 for a little less than the $4400 list price.

I am a long time (10 years) Powermatic 3520B owner and a big fan. I purchased my model B on 4/1/2008 for $2700.

I am writing this blog entry because I was frustrated by the lack of real photos on the web before purchasing my Powermatic 3520C. There were some glamour shots put out by Powermatic. But, not much else.

Note: I also own 2 Oneway 2436 lathes, a VB36 lathe, a mini lathe and a metal lathe.

In a Nutshell

After a month or so of use, I think I am going to also be a long time big fan of the new Powermatic 3520C Lathe.

There are some things I don't like. Like it does not come with a power cord. It still has the offset Banjo that I can't live with. But, overall I am really happy.

It is really nice to see a company make a new model that is beefier than the old model rather than making things more flimsy to cut costs! For example, the base of new headstock is wider than the old one and it weighs more!

In my not so humble opinion the new model C is is at least as good as the old model B and probably a little better.

From now on I am going to abbreviate Powermatic as PM. Model C is PM 3520C. Model B is PM 3520B.

Photo: New PM 3520C Lathe Specs for Reference New PM 3520C Lathe Specs for Reference

Click on the photo at the right for new model C specs that I do not mention in this blog entry.

I downloaded this info from the PM web site.

Part 1: Unboxing and Set Up

Photo: Lathe on Pallet Lathe on Pallet

The lathe comes nicely packaged on a Pallet. It fits in a small pickup no problem.

I had help loading it. I unloaded it on my own by unpacking the pallet while it was still on the truck.

I mostly set up the lathe on my own. I needed help turning the stand over after bolting on the legs. And I needed help lifting the Headstock up onto the bed.

Photo: Cast Iron is NOT Light Weight Cast Iron is NOT Light Weight

The PM web info says the lathe weights 726 lbs and the label on the box agrees.

The label says the shipping pallet weight is 770 lbs.

I weighed each of the parts as I unpacked things. I used a modem electronic bathroom sale so all weights are approximate. Probably +/- 2 lbs.

Here is what I found for the new model C:

Headstock: 160 lbs
Tailstock: 53 lbs (the Old model B Tailstock is 46 lbs)

Banjo: 34 lbs
Tool Rest: 5 lbs
Box of Parts: 18 lbs

Main Leg: 70 lbs each
Leg Riser Block: 28 lbs each

Bed: I can't lift the Bed so here is my guess:
726-160-53-34-5-18-70-70-28-28 = 260 lbs

The above weights are with the cast iron triangle shaped duplicating bracket installed on the headstock and NOT installed on the tailstock. i.e. the way the lathe is shipped.

Note: Should I call it the lathe "bed" or "ways"? I decided to go with "bed". Same as PM spec sheet. The "ways" are just the top part of the "bed".

Photo: Shipping Carton Removed Shipping Carton Removed

The shipping carton was made to be easily removed. Just cut the straps and lift it up.

The photo shows what I found under the cardboard carton.

Lathe bed in the middle with legs in cartons on each side. The small carton that fell down is the all the nuts, bolts, and other small parts.

Photo: A Leg A Leg

Each leg is 22-1/4" tall and weights 70 lbs. (Leg height with out the silver feet that go on the bottom.)

Nicely packaged. Easy to remove. No shipping grease or oil BS that I need to deal with.

When I first saw a photo of the new model C, I did not like the new leg shape. Not as sexy?

I fell in love with the new shape when I built my own self to go under the lathe. The new leg shape makes shelves easier to enclose. No stupid big opening (hole) in the leg that collects dust and shavings. The new legs don't have a funny curve that gets in the way of things stacked on the shelf and thus gives you more room on the shelf. Stay tuned, for a new blog entry coming soon with my new weighted shelf design.

Photo: A Leg Riser Block A Leg Riser Block

Each riser block is 4-1/4" tall and weights 28 lbs.

Thus the legs with riser blocks weight 70 + 28 = 98 lbs.

I have the riser blocks installed on my lathe with the silver feet screwed all the way in. From floor to bottom of riser is 5/8". Thus the silver feet on the bottom add 5/8" minimum. Note: I DO NOT have the nut installed between the top of the feet and bottom of leg. The nut would add another 3/8".

From floor to top of ways (bed) is 34-3/4". The distance from top of ways (bed) to center of spindle is 10-3/8". So the center of my spindle is 45-1/8" above the floor.

If no riser blocks it would be 45-1/8" minus 4-1/4" = 40-7/8" above the floor. This is very close to the 40-5/8" spec on PM web site.

The bed is 7-3/4" tall.

If you wanted to make the lathe taller you can crank out the feet a few inches. Or, I see no reason why you could not add more riser blocks. See "Installing The Riser Blocks" below.

The PM web says the riser block adds 6". This is about right if you crank out the feet, under a 4-1/4" riser block.

The old model B only had one leg option. No riser block. The lowest possible spindle height was 45" above the floor. I just measured it on my old PM 3520B.

Note: The distance between the feet on the bottom of legs is the same on model B and C. 21″ center to center.

Photo: The Tool Rest The Tool Rest

The lathe only comes with one tool rest. It is 14" long and weights 5 lbs. Same as model B.

Photo: Box of Parts Box of Parts

Nuts, bolts, feet, wrench, live center, etc.

Photo: Owners Manual Owners Manual

I really like the owners manual. PM ships 3 SEPERATE owners manuals. One in English. One in Spanish. And one in French?

I am stick to death of owners manuals with just a couple of pages of English text and then a ton of useless paper in other languages.

The Owners Manual has one very serious problem. It does not tell you how to hook up the power cord that you MUST supply on your own. More about that later.

Photo: Headstock, Banjo and Tailstock Headstock, Banjo and Tailstock

This is how they ship the Headstock, Banjo and Tailstock.

They are just locked down to the bed via the silver handles. No extra, nuts, bolts or other BS you need to remove. It seems to work just fine.

I was also VERY delighted to find bare metal surfaces coated with just a light coat of machine oil. NOT that heavy crap you have to remove with kerosene. Like, the stuff you find on cheap tools shipped from China, etc.

Photo: Banjo and Tailstock Removed Banjo and Tailstock Removed

Removing the banjo and tailstock was easy. Then the pallet was light enough that I could slide it out.

Photo: Removing Headstock Removing Headstock

I slide the pallet back in a little and then removed the Headstock. I let it sit on end of tailgate while I got up my nerve.

It feels a like a lot more than 160 lbs at this point. It is not easy to grip, but not to bad.

Photo: Headstock on Dolly Headstock on Dolly

I set the headstock down on to a dolly and rolled it into my studio.

This went ok. But, I decided there was no way I was going to be able to pick it up and install it on bed. I could pick it up. But, I could not pick it up and align the big washer on the bottom of headstock with the ways on my own. I was going to need help.

Photo: Ramp to Unload the Bed Ramp to Unload the Bed

The bed is to heavy for me to lift by myself. To awkward.

I think it is 260 lbs. Not really sure. See "Cast Iron is NOT Light Weight" above.

I got my 2×10 ramps. The ones I use to load and unload my snow blower, rototiller, etc.

Photo: Down the Ramp Down the Ramp

I decided that removing the bed from the pallet was going to be awkward in the truck. So I just slide the pallet down my ramps. No problem

Photo: All Unloaded All Unloaded

Here are all the big parts after I unloaded everything.

Eventually I just rolled the bed off the pallet onto some rubber floor mats.

Note: The model B big useless metal Guard Assembly (that sort of looks like a metal spider web) no longer ships with the model C lathe. It is now an option. So, you no longer have to pay for this big waste of money.

Photo: Contents of the Parts Box Contents of the Parts Box

Here is what was in the parts box after I unwrapped things.

The new model C still comes with the very good "Jet" knockoff of the Oneway heavy duty dual ball bearing live center. The black thing above the big yellow wrench in the photo. The Oneway center is my absolute favorite. The Jet knockoff is a very close second. What's the difference? The threaded part on the Oneway is made of steel. On the Jet it is aluminum. The Jet only comes with the small aluminum cone.

Note: Jet and PM are owned by the same parent company.

The silve sliding hammer knock out bar with brass tip is best of breed. The model C one is the same as the model B.

The new model C lathe comes with the same cast iron face plate as the model B. They are identical. Ok, but not great. Not shown in this photo. See headstock photos above.

Photo: The Feet The Feet

I really like these feet.

Most feet these days are hard plastic with a steel stud sticking out of the top. These feet are mostly steel with just the hard plastic part on the bottom. They look real sturdy.

I removed the nuts you see on the feet before I installed them. This allowed me to crank the feet all the way in and get the lowest possible spindle height with the riser blocks. My floor to center of spindle height with riser blocks is 45-1/8". I wanted my new PM 3520C spindle height to be the same as my old PM 3520B spindle height of 45". Because, I have grown to like that height.

See "A Leg Riser Block" above for more measurement info.

Photo: Installing the Legs Installing the Legs

Here you can see I rolled the bed off of the pallet onto a rubber mat.

The legs are easy to install with a Allen wrench. You just have to put in the 4 black socket head cap screws.

Photo: Installing the Riser Blocks Installing the Riser Blocks

Here I show 2 options for the photo. I show one of the silver feet installed directly in the leg and one installed in the riser block.

The bottom of the legs are threaded to accept the feet. The bottom hole in the riser block is a threaded like hole in leg to accept feet. The top hole in the riser block is NOT threaded. You just install a bolt (socket head cap screw) thru unthreaded hole in riser block into the threaded foot hole in leg.

I really like the riser block design. It is simple and cost effect. I really don't understand whey more lathe manufactures don't go this way. The new Oneway adjustable legs are really expensive. Like twice the cost of the old non adjustable legs.

I see no reason why you could not add more riser blocks if you want to make the lathe taller. I would just make my own. Go to my local steel supplier and ask them to cut me some 3/16" wall thickness, 4" square hollow tub to length. Then drill some holes in them to line up with existing leg foot holes. My steel supplier has lots of scrap cut offs for cheap. You can get 4×4, or 2×4 or 4×6 square tub. 3/16" or 1/4" wall thickness.

The adjustable legs on the Robust lathes, etc are nice. But, lets face it. You probably are only going to adjust them once or twice. Adding or removing a riser block is simple and cost effect. Robust and PM are the same when it comes to changing leg heights. You have to jack up the lathe.

If you want more leg height adjustment in finer intervals then you can just crank the feet on the bottom of the legs in or out.

See "A Leg Riser Block" above for more measurement info.

Note: The distance between the feet on the bottom of legs is the same on model B and C. 21″ center to center.

Photo: Legs, Riser Blocks, and Feet Installed Legs, Riser Blocks, and Feet Installed

Ready to go. But, I decided that thus sucker was to heavy for me to turn up on my own. I would also need help installing the Headstock. So, why take a chance?

Time to find some friends.

Note: In this photo and previous photo I still have the nuts installed between the feet and bottom of leg (riser block). Eventually, I removed those to take the spindle height down to 45-1/8". Like my old B model at 45".

Photo: All Set Up and Ready To Go All Set Up and Ready To Go

It's a thing of great beauty!

Well, not really ready to go. I can’t plug it in and give it a go because the PM people DID NOT ship it with a power cord and plug. Err……!!! See "Main Power On/Off Switch" below.

See "A Leg Riser Block" above for spindle height measurement, etc.

Here is what the new headstock looks like.

It still has the same nice silver hand wheel.

Note: This photo was taken recently, after I installed my new shelf on top of the headstock. Ignore it for now. I will talk about it in a future blog append.

New and Old Headstocks Side by Side Photo: New and Old Headstocks Side by Side

I put 2 different photos together here in Photoshop. So things don't line up perfect. But, they are good enough.

The PM 3520C is on the left. The PM 3520B is on the right.

Basically they flipped the controls and belts from left to right.

They added a new spindle nose on the right of the model C (pointed to by red arrow) by removing the funny overhang on the left of the old model B (pointed to by blue arrow). I really like this. The new spindle nose makes it easier to turn things close to the headstock.

I also really like it because they did not change the distance between the in board and out board bearings. i.e. the distance between the green arrows on both headstocks is the same. Roughly 11.5". The bearings on model B and C appear to be the same great bearings.

Having a nice big bearing on the out board side, in addition to the in board side makes the spindle a lot more stable when you mount pieces on the lathe. It is what makes the PM lathes a lot better than the Jet, etc "look alikes". Often the "look alikes" use a smaller bearing on the out board side or no bearing at all!

The bearings on the PM lathes put them in the high end class, with Oneway, Robust, etc.

Note: In the photo, the "out board" side is on the left where the hand wheel mounts. The "in board" side is on the right.

The base of the new model C headstock is 10" wide. That is roughly 2" wider than the old headstock. This improves the stability of the headstock.

The model C is 15" tall. This is 1/4" taller than the old model B.

The distance from top of ways to center of spindle is the same 10-3/8" on model B and C.

Photo: New Control Box New Control Box

Photo of the new movable control box for on/off, direction and speed in the DOCKED position. Pointed to by red arrow.

The new model C uses on/off buttons. I am having a little trouble getting use to this. However, I still think it is an improvement over the model B that used a single red mushroom button that you had pull out for on and push in for off. The push in for off was probably better. However, pulling the old model B button out was really hard. It took like a team of strong men to pull that button out. That, is why I replaced it on my old model B with a nice twist switch. Visible in the previous photo.

The magnet on the back of the control box is good. Not to strong and not to weak. The entire back of the box is covered with a nice thin layer of soft foam that appears to be fairly tough. No photo of back because I already have to many photos in this blog entry.

Photo: Undocked Control Box Undocked Control Box

This photo shows the new movable control box removed from the dock.

The red arrow points to the nice dock. It is recessed so the docked control box does not stick out..

Note: A moveable control box is a nice safety improvement. However, I still feel, that for safety reasons, all lathes should be equipped with a second emergency off switch that lives on the tailstock end of the lathe. It is ALWAYS there when you reach for it in an emergency. Regardless of where the other control box may have gotten to during daily use.

Photo: The Belts and Pulleys The Belts and Pulleys

This is often one of the first things I look at on lathes. To many people pay to much attention to just the HP of a lathe. They fail to look at the belts, bearings, etc. If you JUST put a big engine in a VW Bug car then you still have just a VW Bug. Because the suspension, tires, etc can't handle all of the HP of a big engine.

The new model C has the same great belts and pulleys as the model B.

The BIG belts and pulleys is another thing that puts the PM lathes in the same high end class as Oneway, Robust, etc.

The PM lathes have great motors with belts and pulleys that are really up to the job.

Photo: New Spindle Lock Knob New Spindle Lock Knob

The new spindle lock knob is above the control box. Pointed to by red arrow.

It is big and easy to use. Just twist it to lock or unlock the spindle.

On both the model B and C, there is no micro switch attached to spindle lock that prevents you from turning on the lathe. I don't think this is a big problem. We all drive cars. You just got to known, when the light is red you don't pull out! You wait for the green. When the spindle is locked. Don't try to turn the lathe on!

Note: The old model B originally had a spindle lock that people did not like. Because you had to manually hold it in. I agree it was a pain. Eventually PM came out with a nice little fix. A sliding piece of metal that held it in. You can see it in the photo above of B and C headstocks side by side.

Photo: Spindle Lock Implementation Spindle Lock Implementation

This photo shows how the spindle lock is implement. The red arrow points to the round washer where the spindle lock pin engages.

No change here. Basically the same on model B and C.

I like what I see. The spindle lock has nothing to do with the indexing mechanism. It is a big robust spindle lock. So when you screw things on and off of the spindle you don't put any stress on the indexing mechanism.

Photo: Index Pin Index Pin

The red arrow in photo points the new model C index pin. The index is now implement like most other lathes. The index pin goes into holes in the pulley wheel. See next photo.

The index pin is held out by a spring. If you want to engage it you just push in. If you want it to stay engaged you have to thread the pin in.

Indexing on the old model B was a big mess. On the in board side, you had to screw a pin into holes you could not see. There was more than one hole for index pin … It was basically, totally useless. The new model C is a big improvement.

Note: Initially I had trouble getting the pin to thread into the hole. It just would not thread in there. Now, it seems to work. I am baffled. I think the threads in the cast iron headstock are not the best. This is the only manufacturing or shipping problem that I ran into with the new lathe.

Photo: Index Pin Implementation Index Pin Implementation

The red arrow in photo shows the index pin coming thru the headstock. See previous photo.

The blue arrow points to the holes that the index pin engages.

There are 48 holes. For me, this is WAY MORE holes than I need!

I generally only need 12 or less holes. More holes JUST leads to more mistakes. Trying to use every 4th hole to get 12 divisions. Always gets me all screwed up. I really prefer to use an after market external indexing wheel. I can then easily mark every other hole with a red magic marker, every 4th hole with a blue magic marker, etc.

Photo: New Digital Index Feature New Digital Index Feature

The model C comes with a new digital index feature. You activate it by pushing the "Index / Indice" button pointed to by blue arrow in photo.

When engaged the digital display (pointed to by red arrow in photo) shows the index number. 1 to 48. In photo it is showing index position 42. When you turn the spindle the index number changes.

I don't known of any other lathe that has this feature.

I am sure, some people are going to love it. It does not do much for me. If I could tell it, I want only 12 index positions and it took care of skipping to every 4th hole it would be of more interest to me.

Note: I tried several times, I just could not get a good photo here. In the real world the digital display that is hard to read in the photo is bright and easy to read.

Photo: Digital Index Implementation Digital Index Implementation

The big silver disk and black box pointed to by red and blue arrows in this photo are all new on the model C.

I think they have something to do with the new digital index function. On the old model B there is just a small laser and sensor that senses the actual spindle speed of the square spindle lock washer.

Behind the blue arrow in photo there is a black plastic box with wires and a circuit board. I am happy to see it is protected from the pulleys by a steel plate.

On top of the steel plate there is a laser and sensor that uses the hole in the silver disk to sense the actual spindle speed.

The model B and C lathes sense and display the ACTUAL spindle speed. If you hand rotate the spindle with the motor off the digital display shows your hand rotation rpm. This is a lot better than cheap lathes that do not show the actual speed. They just show you were the variable speed knob (dial) is set.

Photo: New VFD Enclosure New VFD Enclosure

Some people refer to the "Variable Frequency Drive" (VFD) as the "motor controller", etc

The VFD on the back of the model C headstock is now enclosed in a new fancy plastic box. My feelings about this are mixed. Will the VFD overheat when it does not get enough air flow? I am hoping PM knows what they are doing here.

The VFD on the back of the old model B headstock was not enclosed. This made securing the wiring a little more problematic and time consuming to manufacture?

New or foreign safety standards, etc may have led PM to add the enclosure. The PM web says "Fully enclosed VDF for increased user protection."

Note: A VFD allows you to get high torque out of a motor at low speeds by using a 3 Phase (rather than a Single Phase) motor. The VFD converts 220 volts Single Phase input power (standard household current) to 220 volt 3 Phase power for the motor. It varies the frequency of the 3 Phase power to control the motor speed.

The on/off, direction and speed, control box on the front of the lathe sends low voltage (typically 24 volts AC) control signals to the VFD on the back. So all high voltage wiring is limited to the back of the lathe. This is pretty much standard today on all high end lathes.

Photo: The VFD The VFD

Here is what the VFD looks like with the covers removed. I am an Electrical Engineer. So, you known, I just had to take that cover off.

Photo: VFD Model VFD Model

Here is the VFD model number in photo. It looks like it is a E series VFD at

The VFD is made by "Delta". I am not really sure, but I don't think this "Delta" company is the same as the old Delta Power Tools company. Or maybe it is spin off?

Delta VFDs are not as widely known as other brands because they do a lot of OEM stuff. However, they are known to be a good brand.

The VFD on my old PM 3520B was a Delta VFD. An older model. It works good. No problems!

Photo: Main Power On/Off Switch Main Power On/Off Switch

The Knob under the VFD on a silver background is the Main Power On/Off Switch. It is unconventional. But it is a nice high quality switch.

The old model B did not come with a main power switch. The VFD was always powered on if the lathe was plugged in. This was a huge over site in my not so humble opinion. I added my own on/off switch to the back of my model B. Thus, I am really glade to see the new switch on the model C.

On the other hand the PM people really irked me. No, that is not strong enough. They really, really, really pissed me off by not shipping the lathe with a power cord. I could not plug the lathe in when I was ready to show it to my friends who helped me set it up! I had to wait a day, go to the store again to get a cord and plug, … I was pissed!

I payed $4xxx.00 for this lathe. They could not afford to ship it with a $10 power cord? Come on?

We have standards in the USA. The lathe power plate says 230 volts, 10 amps, 1 phase, 60 hertz. i.e. for USA sale only. The manual says it should plug into a 20 amp circuit. In the US the standard plug is a NEMA 6-20 for 250 volts, 20 amps with ground. The lathe should come with this cord and plug!

Yes, there are some industrial places were they might use other plugs, or direct wire, but those places are 3 phase, etc. They ship this lathe with a single phase VFD, and plate says 1 phase … thus there is no excuse for not shipping a NEMA 6-20 cord and plug! If someone does not like that plug then they can cut if off!

To top it all off. There is ABSOLUTELY no place in the PM Manual they shipped with the lathe that shows how to wire up that switch!!! And it is a non standard switch! The manual says you should hire an electrician!

They want me to hire an electrician, wait for him to show, pay him $100 or more, … Because, they did not want to ship a $4xxx.00 lathe with a $10 power cord? Err…..!!!

I added the blue cord you see in photo and my own standard NEMA 6-20 plug from Home Depot. Note: The plug is NOT shown in photo.

Photo: Lathe Plate Lathe Plate

See photo for all the lathe plate information.

It correctly shows the lathe should be connected to a 1 phase, 220 volt power source.

Photo: Motor Plate Motor Plate

See photo for all the motor plate information.

I am glade to see here they are correctly showing the motor as a 3 phase motor. The VFD converts from 220 volts 1 phase to 220 volts 3 phase for the motor.

The motor on my old model B has been a great motor for 10 years. I think it is really a good old fashion 2 HP into a load. Rather than foreign crap where they falsely label motors as 2 HP when they can not deliver that under load.

The motor on my old model B is one of the lathes biggest selling points! It appears the motor on the new model C is the same motor. It looks the same and all the plate numbers, amps, HP, etc are the same.

However, it seems like the fan built into the new model C motor moves more air. This could be just my imagination. More air is a better thing. Better cooling. However, I have never had any problems with the model B over heating.

New and Old Tailstocks Side by Side Photo: New and Old Tailstocks Side by Side

The PM 3520C is on the left. The PM 3520B is on the right.

The model C tailstock is a huge improvement over the model B because it has Acme threads in the Quill (the part that screws in and out). It took like forever to crank the old mode B tailstock in or out. The new model C is faster.

The PM web site says the model C has a "anti-rotation" key. Well, the old model B also has one. The new one on the model C looks like it might be better. But, I never had any complaints about the old model B one.

They both have the same great hand wheel. They both have the same good quill locking mechanism (the black handle on top).

The model C has a new very nice silver locking handle.

They both have the same hidden compartment with door that some people love. I absolutely hate it when people hide things in there!

The model C tailstock is 53 lbs. The model B is 46 lbs. I personally could do with out the extra weight. The old one was already on the to heavy side when I wanted to remove it. However, on the plus side, the new one is not some light weight piece of junk.

The new model C quill is marked in both inches and millimeters. Good type size nice and dark but still sharp. Easy to read.

The new model C is obviously wider than the model B at the bottom. The model C is 9" wide at bottom. The model B is 7". At the top, where the quill goes thru they are both the same 8-1/4" wide. Both models are the same height. 13.25" to the top of the hand wheel.

The new model C sticks out more on the left. I am really not thrilled with this because it means I can't get the Banjo as close to the tailstock as I would like. More about this latter.

However, it is nice to have a bigger tailstock base in contact with the bed. It makes the tailstock more stable.

Photo: Bottom of Tailstock Bottom of Tailstock

Here is what the bottom of the tailstock looks like. The model C and model B are very similar.

New and Old Banjos Side by Side Photo: New and Old Banjos Side by Side

Oneway 2407 banjo on left. PM 3520C is in the center. PM 3520B is on the right.

The new model C banjo is roughly the same size and weight as the old model B. The model C has a nice new silver handle. The model C features a new tool rest clamp. More about that latter.

Both the model B and C have an offset tool rest post that I really DO NOT like! They are also to short.

Photo: Oneway Banjo Oneway Banjo

This photo shows why I do not like the PM banjos with a offset tool rest post.

I turn mostly bowls and hollow forms from green logs. In this photo I just finished facing off the end of a log so I can mount a face plate.

With my Oneway banjo in there I have to crank out the quill on the tailstock roughly 2". Blue arrow in photo. This is reasonable and safe.

If I had the PM banjo in there (see previous photo) then I would need to crank out the quill another 2" to get the offset tool rest post in the same space. That would extend the quill to roughly 4". Way to close to the max quill extension of 4-1/2". At 4" the quill is not secure enough for strength and safety because it is extended to far. When the quill gets to the end of the threads a 4-3/4" it just slides out. If I have to do this once and a while then ok. But, every day, no way!

In my not some humble opinion the Oneway banjo is still best of breed. Still way better than the model B or C PM banjo because it is not offset.

Photo: New Tool Rest Clamp for Photo New Tool Rest Clamp for Photo

The top of the new model C banjo features a new tool rest shaft clamp. It is huge improvement over the old model C. It holds the tool rest post, rock solid, even under heavy loads.

This photo shows the new design slid out so you can see what it looks like. The next photo shows it installed.

Photo: New Tool Rest Clamp Installed New Tool Rest Clamp Installed

The red arrow points to the jaws that actually clamp down on the tool rest post. It looks almost the same as a Oneway banjo when you look down the tool post hole.

The new PM design is as good as the Oneway tool rest clamp and probably a lot cheaper to manufacture.

Note: The old model B design really sucked! It was just a knob with a screw that screwed in or out. See photo above. It was like the one you find on most cheap lathes. It allowed the tool rest to move around or drop down while you were trying to turn. Extremely frustrating when you have to stop the lathe to fix the tool rest position.

Photo: Bottom of Banjo Bottom of Banjo

The bottom of new model C banjo looks the same as the old model B. Same good design on the bottom.

I really like the big black ROUND black washer (red arrow in photo) on the bottom of the PM model B and C headstock, tailstock and banjo. It is way better than the square washers used by most (all other?) lathe manufacturers.

Round washers DO NOT have any sharp corners that hang up when you slide things around on the lathe bed (ways). The PM round washer is big and beefy!

The square washers use by other lathe manufactures have sharp corners that hang up and prevent you from easily sliding the banjo around. I really hate how the square washer banjos start to stick after they have been used for a while. This seems to be aggravated by using washers that are NOT big and beefy. Over time they bend and distort? Eventually, you have to remove the square washer from the bottom and file off all the sharp edges. Then it still is not as good as the big beefy PM round washer.

Photo: Banjo To Low Banjo To Low

The banjo on the new model C is still way to low. Just like it was on the model B. This has not been fixed.

The banjos on PM lathes are roughly 1-1/2" lower than the banjos on all other lathes by all other manufactures. See red arrow in photo. PM tools rests are extra tall to compensate for this.

This is NOT a great feature. It means that if you purchase an after market tool rest from any other manufacture it will NOT work on a PM lathe. The tool rest post will be to short because the PM banjo is to low!

It is often necessary to purchase after market tool rests for shapes and lengths not offered by PM. Purchasing special rests with longer shafts, cost extra and limits your options.

Photo: New Model C Bed and Leg Holes New Model C Bed and Leg Holes

See next photo for old model B bed and leg holes.

Like I already said. After getting use to it. I like the shape of the new model C leg. It works better when you make your own shelf under the lathe.

However, some users may not be happy with the new screw hold pattern. The red arrows in this photo and next photo points to holes that are in the same location on model B and C lathes. They are 4" apart and 2-3/4" down from top of bed.

The blue arrows point to new holes on the model C. They do not exist on the model B. The model B only had one hole in the middle. See green arrow in next photo.

I think this means you CAN NOT mount the old model B bed extension #6294727B on a new model C lathe. Well, maybe you still can, but you can't use all 3 holes, just the top 2. Or you are going to have to drill your own center hole

You can get a new model C bed extension. PM # 1353002.

I think the old model B Tail Stock Swing Away #6294721 accessory will work on a model C. Because it only uses the top holes. The PM model C manual seems to imply that.

I don't want to be negative here! Lots of people have Tail Stock Swing Away. I do not known of any one who has a bed extension on a model B. You don't really need one because you can just slide the headstock down to where you need it for outboard turning. So the new model B hole pattern is probably not a big deal.

Note: The distance between the ways is the same on model B and C. 2-1/2" inches. The distance between the feet on the bottom of legs is also the same on model B and C. 21″ center to center. The feet are NOT shown in these photos.

The End

Like I already said above. I am big fan of the old PM model B and a long time owner. I think, after a month or so of use, I am going to also be a long time big fan of the new PM model C.

The only real thing I don’t like and can’t live with is the PM banjo. I am going to continue to use a Oneway banjo on my new model C lathe, like I did on my old model B.
