I read Kuhnhausen's book and it hinted at the need for receiver face and inner stop ring fixtures, but did not give sources, drawings, or the requirements of such fixtures.
My frustration with the organization of that book was somewhat relieved by reading Walsh's more organized book on Mausers, but he only had drawings for basic tooling like action wrenches.

The key to making a home made inner stop ring fixture for me was a ground pin in a reamed hole. This fit is so precise, one can feel the difference between lubricants.

Just another clarification, when I wrote "full contact" I meant a slight rub mark on the bearing surface, not always the full radius of the mark on the surface. Some places rubbed a bit more of the sharpie pen off than others, but in the sunlight, there was a slight mark in all the places I was looking for.

If I hosed it up, I hosed it up; I probably won't do it again. I can handle being imperfect. But my guess is that it'll be just fine when all the pieces and parts come together.

It's just fun (isn't it?) taking an old, possibly abused, definitely neglected hunk of steel and wood and making something useful and unique out of it. That's my reason for doing it. If I just wanted a gun, I could head to WallyWorld and buy one straight off the assembly line.

Anyways, do you guys smell a dead horse around these here parts? I sure do. I'm thinking this thread should come to a timely end before it starts getting personal on techniques and theories.
