question for Rick, Rich, Hugh and others that have twisted on a barrel or two...
 

Hi Guys, I've learned a lot in the past few weeks, but can always learn more from the, "Been there, done that!" bunch.. I know all you guys have been at the same spot in the learning curve as I am at now.. My question is?? Have any of you pursued, or thought of pursuing, taps and dies for the receiver threads and barrel shank?? Also, would cleaning (with taps & dies) the threads affect timing to some degree??......:eek:.. Let me know what you think... best to all, til...lat'r....GT:cheers:

Haven't done any Lugers, but I have done a few S&Ws. The Luger barrel has a shoulder that appears to be what defines the timing when it contacts the extension. I would be surprised if taps and dies were available in that pitch. Standard taps and dies are ground to differing specs and are graded as to % of thread engagement. I've run taps and dies through new nuts and bolts and am often surprised at how much metal is removed sometimes. A situation like that would likely change the timing. If I were doing this swap, I think I would just clean both threads with a fine wire brush and use something to keep the threads from galling. :cheers: Joe

Hi Joe...
 

Hi Joe! Thanks for the reply...that's kinda how I feel... It's just with lot'sa force, it's tough to know where your at with resistance most of the way... Hey, while we're here! Things are getting better every day down here..I haven't forgotten you... I'll be in touch soon! Best to you Joe, til...lat'r....GT:cheers:

I have never had a need for a tap.
I do however have a very sad 1906 Navy where is likely will be needed, and in such case I am likely going to make the tap myself.

tap & die...
 

I'm going to get a little more familiar with all, and then maybe revisit the tap & die thing when I have more experience... I'm going to set aside as near perfect receiver and barrel as I can for my benchmark test pieces... Thanks Hakan for your reply, best to all, til...lat'r....GT

I agree with Joe. I always used Neverseeze thread dope. When I encountered a tight fit between bbl and receiver, I would go slow, turning in a round and then backing out and then going in two rounds and backing out one, etc. Usually new bbls never lined up and a small amount had to be turned off the flange to get correct. This is the tricky part, take too much off and buy another bbl!!!:eek:
