Topic tags/keywords: vise woodworking vise carpenters vise face vise

After much searching and waiting, I just acquired for free (gloating) an old beat-up woodworking vise – a 4”x7” non-quick release face vise made by N. Slater Co. Ltd., Hamilton, Ontario, Canada (1917-1979). I just read over someone’s meticulous revival of the exact same vise (lots of pictures) here:

HOWEVER the bad news is, other than pitted rust, the 7/8” acme-thread main screw is bent very slightly at the 2”-3” open position causing it to bind significantly – very not good. The vise came from an old primary school 27” high woodworking bench – the kids were probably leaning on it a lot at some point or the bench fell over with the vise open, although the guide rods are totally straight (?).

Anyhow, the vise has been taken apart, and I’m thinking of propping the vise main screw up on some 2×4 supports and smacking it hard with a small sledgehammer and a piece of hardwood after propane torch heating it up as hot as possible first, to bend it straight. Anyone here have a better idea or other DIY recommendations to fix the main screw of this old workhorse, so I can bring it back to life! My first real workbench is waiting impatiently. Thanks in advance.

If it bent without being heated, it should be unbendable without being heated. And the old “smack it hard with a sledgehammer” trick is really better suited for demolishing walls than for coaxing a wayward tool back into position. If you can remove the screw from the vise then you can try putting it in another vise using the three pieces of wood (two on the ends on the concave side, one in the middle on the convex side), slowly tightening the vise until the screw is straight. An arbor press used the same way would also work and you can hold the two ends in v-blocks that way. And if it turns out to be totally butchered, if the pitch is something normal then 7/8 acme threaded rod is readily available online at places like MSC.

Ah yes I see, after heating – bending is better than smacking. Thanks, JJ.
