Didn't sand the glass
off, just thinned it down. 10 strokes on the back of each limb, 10 strokes on the belly of each limb. Continue like thatuntil you get where you want to go. If you need more than 6-7 pounds less, they say you might as well sell that one and make another.
I really don't have a clue on how thin you can take the glass before you run into problems. I'd like to know, if anybody can pass that info along... Might save somebody from getting beaned by a busted limb. (ME, for instance!)
