I have asked several folks how they cut their threads when the barrel and action and also several guys i work with and have heard a few differant ways to do it , I was just wondering if any of you other builders would mind posting how you cut your threads. I personaly use the method I was tought in school by setting the compound to 29.5deg and useing only the compound to make the depth adjustments. I use two dial indicators , one setup to read off the back of the tool post that I use to ensure correct cut depth (don't trust the dials) and one setup on the back side of the lathe bed so that after I make a cut , pull out and bring the carriage back to the start point I go back past the origionla start point and come back to the part where the dial is set at 0 , this ensures that their is no slack in the screws and will start at the exact same place. I pick a number to drop in on and stay with that number the whole process ,my reasoning is that your enguaging gears and that one could have more wear than another and this could have some change on the thread , trying to make everything exacttly the same as the last cut except the cut depth , I also keep a log as to which number I dropped in on last and rotate the numbers so that they all get equal use (i'm very O.C.D. and this helps me sleep at night). when I get to the end of my cut I take the carriage out of gear and let it sit their before I pull the tool out , I don't make an undercut in the barrel I come back at the end and cut the raised portion to the same diameter as the bottom of the thread so that the action will mate up square. I'm probably wasteing time with this process but like I said in my mind this is giving me as close to perfect threads as possible.
