barrel thread die

[tyler.woodard04]

where you guys getting them?

Brownells has them but they aren't cheap.

If you want one I can get it to you for $135 shipped.

They are considerably cheaper here and probably the same quality:

These are for the large shank barrels. No doubt they have them for the small shank barrels as well, but I don't remember the thread size.

I like the prices RWO but I didn't see one for the small shank which is spec'd as 1.055"x20tpi and which measure ~1.045" on the barrels I have.
The large shank is very close to 1.125" (1-1/8") at 1.120"x20tpi so the 1-1/8x20 die would work probably.

[nsaqam]

The 1-1/16x20 (1.0625") might work but the pitch diameter may be too large unless you chased the threads on the receiver with a 1-1/16x20 tap too.

[RWO]

The official Savage thread spec. for the large shank barrel is 1-1/8-20UN-3A, P.D. limits 1.089-1.091, thread OD limits 1.115 - 1.110. So what we have is a 1-1/8" thread with the OD reduced to something less. I suspect the same logic applies to the small shank thread. In any case, the dies are adjustable and will allow some variation in the pitch dia.

I suspect you're right on the reduced OD 1-1/16" shank.

Good info RWO!

[geargrinder]

The 1-1/16"x20 die works. I bought mine from Victor.

I would like to ask why you would use a die nut? If the threads have some dings on it try a thread file first.

If it is a new barrel and the major od is too large you can remove some of the od with a stripe of fine emery. I would never use a die nut on a class one thread. Most dies will remove too much material. I gues it all depends on what your trying to do but from this machinist standpoint a die nut is not the most desirable tool on a critical thread.

working on a nut lock system on some junk barrels and after im done I would like to run one to make sure threads are all good before screwing them back onto the action
