Kilroy08 4 Posted July 22, 2007 Report Share Posted July 22, 2007 Hey, Do any of you guys know the tolerances for making a thread alignment tool and what flavor of steel to use? I'm itching to get my .223 done and this is holding me up. Thanks Quote Link to post Share on other sites
BobAsh 582 Posted July 22, 2007 Report Share Posted July 22, 2007 Thread alignment tool? You mean like for muzzle threading? I would just make it a good slip fit on the barrel, maybe around .003 diametrically, and grease the barrel. Any mild steel should do. Quote Link to post Share on other sites
dinzag 31 Posted July 22, 2007 Report Share Posted July 22, 2007 +1 - about 0.003" undersize of the lands. I usually cut the threads on it first, then chuck on the o.d. of the threads & turn the bore pilot end so it is true to the threads. Quote Link to post Share on other sites
Kilroy08 4 Posted July 23, 2007 Author Report Share Posted July 23, 2007 Thanks guys, Now it's time to bust out my 25th edition of Machinery's Handbook and read the chapters on tap and die making. I figure a die and all three flavors of taps for 14x1 LH should round out the collection of AK tools just nicely. Kilroy Quote Link to post Share on other sites
