semper299 284 Posted February 27, 2012 Report Share Posted February 27, 2012 Installed dinzag bullet guide in 7.62. Of course, after reading all the warnings about breaking off tap, I broke off the tap. Drill lost grip and would not turn tap either direction. While tightening chuck, I bent and snapped the tap. Hit tap with punch, would not break, so I broke out the dremel and ground it smooth in the feed ramp. I then used JB Weld (Steel) to secure the bullet guide in place. It looks great, and seems very secure. Do you think this will hold, or am I just kidding myself? Thanks. Scott Quote Link to post Share on other sites
G O B 3,516 Posted February 27, 2012 Report Share Posted February 27, 2012 FUBAR. Fix it right. Never use a drill to tap anything under 10-32, and then only if you have a steady hand. Tap wrenches work so much better. Quote Link to post Share on other sites
semper299 284 Posted February 27, 2012 Author Report Share Posted February 27, 2012 (edited) You're right, GOB, and I found this out the hard way. How do you think I can "fix it right". Should I just get a larger drill and tap and try it again? And of course a tap wrench Edited February 27, 2012 by Semper299 Quote Link to post Share on other sites
G O B 3,516 Posted February 27, 2012 Report Share Posted February 27, 2012 You have to break up the old tap. Taps are harder than bits and cannot be drilled out. I use RamSet nails. The kind meant to be shot in. For the price of a center punch you get a whole box of them. Quote Link to post Share on other sites
