I've been working on making a bolt handle jig the past couple weeks and finished a few days ago. Figure I would try it out on my Savage BVTS 22. The end result is pretty darn nice and highly functional. I have a couple refinements to make on the jig and my machining process to make the next one better. Thread size I cut was 5/16-24 and the aluminum for the handle is plain old 6061.
