[QUOTE="375 CHEYTAC, post: 616933, member: 42641"] I am curious about the various different techniques used for indicating a barrel when cutting threads on a lathe for muzzle brakes. Most gunsmiths do this for +/- $100. How I have been doing it so far is, separate the barrel from the action. Then run the barrel through the headstock, and using a mini chuck/spider, I indicate both ends of the barrel off of the bore to better than .0005 on each end(on the chambered end I instal a PTG indicator rod and indicate off that). I mostly work on Remingtons, which require my big action wrench to get them apart, this also requires removing the scope and rings and bases. Not the easiest way to make a hundred bucks. Its not so bad when you are installing a new barrel because its not on the rifle yet. Is this method over kill, This method has been producing bench rest quality chambers when chambering. Any Gunsmiths out there willing to share some of there years of experience. I would appreciate any and all opinions. I hope my description of my process makes sense. Cheers Trevor [/QUOTE]
