My current putzing around project with the lathe is to make a handle for a lathe chisel (parting tool, to be specific). So the shank of the chisel is 1/2" and so is (presumably) my hole for it. The chisel is a sort of slip-fit, it slides in without undue pressure and I have a collar for it once finished (1/2 of a 3/4" copper union). The collar will be a very tight fit, but I'm wondering about how tight the shank should fit in the hole. Maybe you're supposed to put a little epoxy on it when inserted??? Or do i need to try and get a tighter fit?
