Over the past couple of years I've spent a lot of time shaping in borrowed bays at glass shops where other shapers are working. I noticed that a couple of shapers were using about a 12" x 2" round foam pad with what appeared to be two different grits of sandpaper or screen: an outer ring (like a dougnut) coupled with a solid center. I didn't pay much attention at the time, but now I'm curious... I'm assuming that the outer grit is finer than the inner, but I'm not sure. I'm thinking it allows a course cut and a fine cut on every pass, always ending with a fine cut. Does anybody on Sways use something similar,and if so, what grits do you use?
i have several,
made from pvc pipe and wood dowels.
some are padded some are not.
my fav is a loped off end of a wood baseball bat.

Actually, Herb, I was thinking of a disk more than a tube. Although, I like the baseball bat idea. Probably a softball bat with more parallel sides. Good for bonzer bottoms I would think...
Louisville slugger. Garage sale special. Wrapped in EVA Yoga Mat foam. Double barrel concaves out the back.
I just made a "concave sanding device" from a section of 6" round pvc pipe and 1/4 " foam cushion Works great. The pads that nomastomas is talking about sounds like a regular soft pad that is being used by hand.
Yes, round like a "Soft pad" but made out of egg carton foam, like the stuff used to pack electronics, with bumps on one side and smooth on the other. Grit is on smooth side .
