Old school wisdom says you can’t sand wet wood. i.e. something you turned out of a fresh log. You have to wait for the wood to dry out, then sand it.
If you try to sand with old school PAPER backed sandpaper the wood turns to mush and almost immediately clogs your sandpaper. You can’t wash off paper backed sandpaper with water. The paper just turns to mush.
Long ago Michael Hosaluk turned me on to using Siasoft Red Foam Backed sandpaper. I really like it. It is tougher than nails and works great on spindle turnings and wet wood. You can wash it out with water. Then reuse it over and over.
