Folks:
Just for your information we have an adapter for those wanting to do rimfire chambers or pistol barrels (small tenon diameter).

I wonder if this isn't a solution to a problem that don't exist. I don't have a problem reaming a chamber to within a thou of what I want.
I have been a machinist, toolmaker, gunsmith for 40 years. I use the stp because it works as advertised and makes chambering simple. You can return the tailstock to any position, no dial indicators, etc needed. I have them on each of the reamers I use the most at work and can cut a chamber in a pressure test (EPVAT) barrel in less than 15 minutes using the stop and a pressure flush system. I have done 10 test barrels in one day all with the exactly the same chamber dimensions.I wonder if this isn't a solution to a problem that don't exist.
