Can't seem to find a tap. Fairly certain the thread is acme. Don't know if I posted this a few years ago or not....but this project has been on back burner and I am back to tackling it again.
I have an old Columbian vise....5" jaws 8" opening. Here it is next to my Wilton bullet for scale.
The issue is the cast piece that is threaded is stripped. But the screw is good. I have kicked around the idea of making a new screw and matching threaded block....but if I could find a tap to cut 1-1/8" x 3 acme threads....I only have to remake the block.
The part is stamped 506-4 and can't seem to just source a new on either.
Anyone got any ideas on a tap before I resort to making both a new rod and block
