Barrel threading kit

I would think you would want them cut on a lathe so that they were a good tight fit. There is bound to be small differences in the thread diameter and depth between individual guns as well as different brands of guns

Tools.

You are free to import tools, as are the Americans free to export them.

Different story on actual gun parts.

All the hand threading tools I have seen for barrels have been pretty craptacular looking.
 
I'm curious how a specific barrel threading tool would function versus a simple die? Does it have some sort of jig to try to keep it concentric to the bore?

When cutting them on the lathe, at least in my experience on the best way to do it without botching it, you need a ground/polished rod of the right diameter to index off the bore, as most rifles do not have the bore dead center in the barrel.
 
It very much depends on the barrel being machined.
Ideally, if a barrel can be passed through the headstock and supported on the left by a spider, and on the right in a 4 jaw chuck, if can be indicated in with a dowel pin in the bore.
Often this isn't possible or practical. The muzzle can be supported on the live tail center. The machining will be concentric to the muzzle. Might be necessary to touch up the crown with a piloted cutter afterwards.

As usual never enough information...

What are you fitting the barrel to? Is the barrel already chambered?

Or are you talking about threading the muzzle for a brake?

Regardless I think both ideas are a terrible way, and neither is very precision.
 
You don't have to be a gunsmith to thread a barrel but using a lathe is a must unless you have had a lot of other barrels to practice on. I am not a machinest but can do a good job on most things I do on my lathe. I use the lathe to do most threading if I can chuck it up. The only time I generally use dies is to chase or extend a thread. Barrels are not cheap or easy to come by. So chuck it up using a proper pilot in the bore or a live center and cut and measure/fit slowly.

Pretty sure he's looking for the piloted kit that has a pin that goes down the bore to keep the alignment.

From memory, most seem to be aimed towards the guys that want to dress up their Moisan's with flash hiders and the like accessories.

Eg:https://www.amazon.ca/Threading-Alignment-Tool-Starter-223/dp/B00JLDXJKU and https://www.cncwarrior.com/5-8-24-RH-Barrel-Threading-Kit-p/25444.htm

A flash hider may not be too critical but if you take it off and screw in a muzzle brake then a couple of degrees off canter could be bad.
