I've been itching for a small side project to meddle with, so I'm gonna try to fix up this Prentiss vise I have. My Dad bought it at a yard sale about 40 some years ago with the work bench for $25. It's a Prentiss #21 5.25" swivel jaw vise. Big heavy sumbitch, around 100 lbs. It's probably my single favorite tool I own. I have no idea how old it is ('40s or '50s maybe?) but I've used it countless times, probably more than any other tool I own.
That said, it's not without it's problems. It's seen some serious use. Both swivels are seized up tight, they were seized when my Dad bought it. My Dad and I have both tried over the years many times to unstick them, even whacking it with a sledge to no avail. Also the front lip has been ground off of the front jaw. My Dad said it was that way when he got it.
Today I began by taking apart what I could and unbolting it from the bench. The jaw faces are a little rough, but new ones are about $100, so I'm going to try to clean them up and reuse them. Someone tried to weld the front jaw face in place at one point so there is a big bead of weld to grind off of it. The screws for the rear face were stripped and seized and had to be drilled which was a bit of a pain, but once the face was off, the remains unscrewed cleanly.
Next I've got to strip the paint off of it and soak it in either vinegar or rust remover or something then get a torch and heat it up so I can try to bust it loose. Hopefully I'll have better luck with it this time. Stay tuned.
I love how it has 'New York, NY' cast into the side.
