[QUOTE="sable tireur, post: 1755898, member: 27307"] I think you're asking about the bolt BODY diameter? With 0.003" being the goal of reduction while keeping the finish good and the reduced diameter accurate, I use a tool post grinder but that's because I have one and make use of it. Buying one of these for just a couple of small jobs is prohibitively expensive. If your skills with insert selection or tool bit grinding is less than you feel you need, find a small grinding shop to handle this for you. Otherwise get some suggestions for the proper insert or the best angle to use for your project. You could cut the bolt on your lathe leaving the diameter slightly fat then use fine sanding material with a flat backer to polish. [/QUOTE]
