I thought I'd post about what I had to do to make this POS Columbian 43 1/2 vise into something that can be used.
Here it is as given to me.
Blown apart. That lead screw clip is pretty cheesy!
After about 45 minutes at the wire wheel and a little file work.
The dynamic jaw on this thing must have suffered some core shift for the lead screw hole. The machinist/machine that finished the bore didn't help it out any either.
I set it up in the mill and cut the bore on the same plane as the slide, then I cut an oilite bushing for a press fit in the bore.
This is the start of the swivel base lock nut I am making from hex brass stock.
This is where I am at on it now. I need to come up with a better lock ring for the lead screw
