Rather than start a new post, I'll revive this one.
Wanted the bolt on the 10/22 I'm building jeweled, like to do things myself if possible.
Got most of the information I needed from this website

Since the article deals with Mauser bolts I had to come up with a way to hold a 10/22 bolt and keep the lines straight. That was the hardest part.
I clamped the bolt in a drill press vice, padded the jaws with rubber gasket material held in place with magnetic strips.
In order to get proper spacing while moving the bolt horizontally I made marks on the drill press plate every 1/8". (The brush diameter is 1/4", used 1/8" for consistant overlap.)
To keep the vice going straight as I moved it I clamped a piece of scrap wood trim to the press to use as a guide. When It was time to make another row I would move the guide back 1/8".
I got the brushes from Brownells. MidwayUSA has them too, but you get three from Brownells for the same price as one from Midway. Good thing I had an extra, while practicing on the vice jaws I put too much pressure on one and spread the bristles out.
The Permatex valve grinding compound is 400 grit.
Finished project.
Did my Sons Ruger too, it came out a little better than mine. Should have used his for practice!
Think I'll do the chamber on my 1911 barrel this afternoon as soon as I figure out a way to hold and index it.
