Found an old Morgan Chicago vise at the local flea market with the only marking of 3-1/2 on it besides the Morgan Chicago. It has a toothed swivel base on it with a threaded rod down through the middle with a wing nut on the bottom. I think the rod goes through the bench surface and is tightened and loosened to lock and swivel the vise. I contacted the Morgan vise people and they said no one there had ever seen such a swivel base like it. Has anyone ever seen such a vise before?
The upload failed. Don't know why.
The only part not shown is the part I need. there's a pin that holds the main nut in place. Is that a standard taper pin or a special part?..Steve
Looks like a useful reference, plus it has a good exploded diagram that identifies each part.
