Recently someone asked me for advice on sanding disks. That is easy!
I like the “Blue Flex” sanding disk sold by Vince’s Wooden Wonders. http://www.vinceswoodnwonders.com
I have been using these for the last 4-5 years and I am very happy.
Note: Recently Craft Supplies USA started selling some “Deerfos” blue sanding disks. I don’t think they are the same. They are made by a different manufacturer. I found something I like and it’s not broke, thus, I am sticking with Vince.
• Blue Flex Disks
The velcro on Blue Flex disks is glued onto a very tough sandpaper. They work wet or dry.
Heat will build up and soften the glue if you sand aggressively with these disks. When you try to remove the disk the velcro will get screwed up. To avoid this problem you need Innerface Pads!
• Innerface Pads
I use 2-3/8” & 3-3/8” to Innerface Pads that match disks.
I use 1/4” thick “Firm Yellow Tapered Innerface Pads” for 80, 120, and 150 grits.
I use 3/8” thick “Soft Blue Innerface Pads” for 150, 180 and 220 grits.
1 interface pad for each grit works best! Allows quick and easy grit change without screwing up the velcro.
• Low Profile Back Up Pads (aka Thin Back Up Pads)
I use 2” & 3” Ulta Thin Back Up Pads. The thing that you chuck up in the drill. 2” pad goes with 2-3/8” disks and interface pads. 3” goes with 3-3/8”
I like the “Ultra Thin Back Up Pads” (only sold by Vince?) better than the thicker pads. They are better are getting into the tight space between headstock and bowl.
If you are using interface pads to adjust softness of pad then you don’t need and really don’t want a thick back up pad with lots of flex.
