[QUOTE="J E Custom, post: 943047, member: 2736"] I am anal about everything and check the bore before I start and then after I thread to see if the stress relieve was good (If not stress relieved properly the bore can increase because of the loss of material removal). After I install the brake I gauge the brake and the bore to make sure everything is in alignment but in the past I have not mike'd the bore after the brake installation but have since started to see if the torque had any effect on the bore. (So far I have note seen any measurable change) I also use the largest thread possible to leave the tenon as large as possible and maintain a minimum of .175 wall thickness based on the bore dia. Some barrels are to small for threading and fluting because the wall thickness gets to thin based on the bore so I don't/won't do them. That may be the reason I have not had that problem (Luck and caution). I will however continue to check for this now that it has been brought up. Thanks for the insight, We are never to old to learn.
