"Back on Face" Problems

[Double Play]

Frank,
Thanks for sharing your procedures in pictures. I’ve made a couple of new roll joints/guide rolls for both hammer and hammerless guns and by adding the needed material was able to achieved the same result with no file fitting. I would be very interested in getting more details on the fixture you used to hold the barrels while machining in case I decide to try the welded hook method. Thanks, Larry

Yes, please show the fixture. Thanks, Tom

I did not have that much contact on the hook but I did have a good amount in the center of the hook. Are not most hinge pins tapered? How do you account for that when milling as end mills are not tapered? I agree that using a vertical end mill would be the best choice and I do have some experience machining. I have access to a vertical mill and even a cnc mill but since it is at my school bringing in a set of barrels is out of the question. I may be able to get the permission, but I doubt it.
