I found an old subject line grinder at an antique mall. In pretty darn good shape, except the tool rest is missing, which I can make one for it. But the hard part (for me so far) is finding a 3/8”-12 Acme swivel bolt.The bolt used to hold the grinder to a bench. All I have left is a 2” length of the bolt with the swivel foot. I need a bolt at least 2-1/2” thread length, and a knob, either butterfly or fluted.

I’ve seen Carr-Lane has swivel bolts, but not sure about the thread. I think their website has a minimum $100.00 purchase requirement.

Has anybody found a good source for Acme swivel bolts?

Thanks for reading,

I’m no help at all on the bolt but that’s a nice looking grinder. Have you measured the ratio of the gears yet? Some of them can run pretty fast. A grinder that size I would expect to be in the 9:1 or 11:1 range.

Thanks! It runs fine. No, I haven’t counted the teeth yet. But it is a very small output gear, to a very large input gear.
