I found this old leg vise today + extra screw.
The wood needs to be replaced on the leg vise, a nut needs to be fabricated for the extra screw.
The fellow I bought this from said it was salvaged from an old planning mill company.
These parts are very old, the threads are square form rather then later Acme. Oddly, the diameter is 1 3/32” on both screws, with the pitch being 6tpi on the leg vise and 5tpi on the extra screw.
Some needed inspiration to build a better work bench for myself.
I have been looking at the cost of leg vise kits, and cost and time fabricating from scratch, I quickly gave $35 for what is there.
I have a piece of easy cutting bronze to make the nut for the extra screw, that will be used for the end vise. Internal square threads are always a challenge, I cant remember ever cutting one that coarse though.
Anyway, a few pieces of the old times there.
