Saands,

Thaks for the input. This is one of those I'm up at 4:30 in the morning and my mind is wandering questions. You are right the Mausers us a Witworth thread, with a 55 degree pressure angle. This is the measure of the thread slope from the root to the crown. I have a set of taps and dies that I use to chase the Witworth threads into ASE 60 degree angles. This way it makes the barrel threading easier. I have heard that some gun plumbers will take a SAE threaded barrel and just screw it in to a Mauser receiver without mating the threads. They will go together okay, they just wouldn't stay tight.

I may try to see if the 1.1" bottoming tap I have will line up on a cracked Turk receiver that I'm using as a paper weight. In an idle moment I did the math using standard drill-tap charts and the .98 is real close to a 80% tap hole. This may actually be too big for a clean thread cut. I'll let you know what happens.

Promised Honey-Bunny Jambalya for supper tonight, gotta go.
