I've acquired a Dan Wesson 445 Super Mag barrel that is in need of thread repair.
It and the shroud were pretty abused. I'm guessing it was a case of a siezed barrel nut and nimrod combination. Brute force rather than proper tools and techniques to get it removed.
The threads into the frame are .675 x 40. Have searched high and low and no one makes that die, unless you want to pay for a one off custom die!
Threads are much too small for my hands to try filing the problem areas. Have looked at a couple of the thread repair tools that use good threads as a guide for a cutter to chase the damaged threads. They are about $72.
I don't have a lathe big enough to handle the barrel but have access to one. I have threaded on it before so understand the basics. I have never tried to chase/cleanup or repair threads using a lathe tho. What is the technique to do so?
Thanks,
Andre`
