ive had to make some shims up for a lathe headstock some 15 thou and some 5 thou. a bit difficult to drill so what I did was put a piece of 10mm bar in the drill vice got a quarter drill bit and drilled a hole through it then took the drill bit out and ground the rear of it flat turned it the wrong way round and put it in the drill chuck pushed right in . put the shimstock over the drilled hole and pulled down hard on the drill handle and punched the holes in them it works well up to 15 thou if your drills up to it
