Thread turning in "action"?..(har har)

I had to cut some threads for a custom single shot bolt action I am working on.

This is and IMI Timberwolf .44 Magnum barrel. I stepped the chamber slightly and put 1.36" of 18 tpi threads on. You can see the extractor slot which was already cut. I simply threaded over it, but I will be using it in my design for extraction purposes.

The major and minor thread diameters give me a chamber thickness of between .126"-.159".

The barrel has no taper and is .796" in diameter, 18.5" long.
