I really appreciate all your responses and yes years ago I did have a small lathe and milling machine but now at 82 years of age they are just a memory. If any one has some 3/8" drill rod, which if I remember is 01 tool steel, I would be more than satisfied if, without even reducing the OD, it could be chucked in the lathe and a 3/16" hole drilled center and then with a measured length of .356 3 or 4 pieces be cut off the rod. I was given a 115 year old Stevens .32 rimfire single shot rifle and the loading lever has a semi circular cut out in it designed to snap over the bushing and semi lock it in place, The bushing that came with the rifle was home made for sure and even the hole was drilled off center but to be honest it does measure around .346 so my original thought of .312 wouldn't work. If I had the full 3/8" diameter I can reduce the OD gradually until I get the perfect fit. I wouldn't need them heat treated as I can do that myself with the old heat to cherry red and oil quench. Also I'm not asking for a freebie I will pay what ever cost is involved plus postage for shipping to Petawawa Ontario.
