I seems that I'm real good at starting projects, but not so good at seeing that I finish them in a timely fashion. I am starting an iron mounted Bivins Rifle in a Rice "B" wt .40 My 1st. steel mounted rifle. What's the best way to make the hinge on a patch box? Do I form it hot or cold? I've made all my patch boxes out of .062 brass, silver soldered the hinge flap closed, but have no experience with a steel patchbox. Do I need to order annealed sheet steel from McCaster Carr? Oh, I have two others on the bench that I'm in the middle of. ...Geo.
