Meta Description: Carl likes Sanding Backup Pads (mandrels) that are thin, low profile and HARD. He makes his own out of 1/4" plywood and 1/4" flat head bolts. He attaches firm and soft foam interface pads to make his hard backup pad softer as needed.
When I need to sand the inside bottom of a vase I like to use a sanding stick made out of styrofoam. The stuff they sell at Home Depot, etc to insulate foundations. They call it “Rigid Foam Board Insulation”. I use the 2″ thick stuff.
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.
Meta Description: Carl recommends "Siasoft Red Foam Backed" sandpaper. 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.
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.
