Was wondering if anyone here has used paper shims in a vise before to make something parallel? Basically was setting up a small rod to be cut in v blocks. The lip of the vise was pretty bad and when I checked to make sure the rod was parallel, was about .002 off. So the first thing that came to me was to stick a couple strips of paper under one of the blocks. It worked. But was belittled by one of the old guys at work telling me a real machinist would never do something like that. Just wondering what you guys think since this is the highest concentration of real machinists that I know. Thanks.
