No, I wasn't kidding. I've used it to peel paint off wood. It works great. You only have dust then and no fumes. Should be appealing to the Thumper. I like 150 Garnet mesh, purchased from Abrasive Products, (317) 485-7701, about $50 for 100 lbs. Just use it in a cheap siphon feed sandblaster. It leaves a surface a little rougher than a sanding with 150 sandpaper.

I'm not sure if you were kidding ot not Dean I did see an article in a woodworking mag on blasting finish off of wood, not with sand but using baking soda and a lower pressure. -- Michael Magness On 8/24/07, Dean May <deanmay at pianorebuilders.com> wrote: Why not try sandblasting?

Quite a lot, I'd suspect. I just picked up this Steinway upright, and found rather thick, gray paint all over thre back posts and soundboard. Gray sandable primer is, I believe rather soft ( = sound absorbing. ) If I have time, I'll get a bunch of carbon filters for my gas-mask, and try to blast it off with lacquer thinner in my spray gun, with a bottle brush to get behind the posts.
