This probably sounds silly but... I have started to turn a few bowls on my metal lathe, I have made a few chisels out of old files and they work really good, I finially decided it was time to get some store bought chisels so I got a set from sears, problem is.. I cant get them to cut..lol.. I have my rest (which is a 1/4 x 2 flat bar) clamped in my aloris tool holder, it is set about 1/4 below center and I let the homemade file/chisel lay flat when turning, when I try to use the chisels from sears they just rub and wont cut, I keep my rest about 1/4 away from the wood, are the new sears chisels supposed to be held up at a angle? If so this would mean my rest would have to be way below center. thanks!
