[MemphisMachinists]

Probably easier(cheaper) to make new ones. If you can't find a local machinist to help at a reasonable price let me know. I will try to help. Lots of machinists are gun nuts and don't mind helpin a bro out. All I need is the I.D, of the hole in your vise, how long you want them and what kind of material you want them mad from. I had never thought about making them from brass, but it might be a good choice, because of the available stock brass bushings. It would be likely that bushings close to size would be available. Turn OD, bore ID, split with saw and walai less than 1 hr. bushings.
Edit: I just looked in Brownells catalouge. It says bushings are 3" long and 1 3/4" diameter. Is that what you have?

Thanks Ripsaw! Thats a great idea. Never would have thought of it if you hadn't brought it up.

I am gonna have a machinist in town hog out the small M1 Garand bushing to match the other one tomorrow, and just make Garand ones out of wood, maybe.
