I am hoping to finally start rebarreling my Chilean model 95 mauser actions this winter. Gunsmith Ron Henrickson who goes by Speerchucker on many forums has a long thread over on the gunsmithing forum where he gives the spec's on small ring mauser actions. He mentions that some have 55 degree whitworth and some have 60 degree imperial threads. I happen to have both imperial and whitworth thread gauges. I have tried both and can't really tell any difference in the fit. My plan is to do make a short test bar where I thread one end with 12tpi whitworth and the other end with 12tpi imperial to see which fits the best. I will have to grind a HSS whitworth tool bit. Any tips on how to grind this would be appreciated. Speerchucker also says the threads need to be a class 4 fit. How do you achieve a class 4 fit?
Thanks for any help you guys can provide.
