I got two new to me leg vices I want to restore any advice is apriciated
Let’s see some shots of it, I’d be happy to help. First things first if you are looking to restore them to the best you can, you’ll need to start taking off rust with a wire wheel or other method and start taking apart the entire vise. Clean out the grease out of the gearbox, clean up the threads and inspect them for condition.
Posting photos will help me give you some more specifics.
