Looks like the die head that threaded your spindle was run with little or no cutting oil. Threads were cut with a die head on a one shot thread operation, this is after the rod is friction welded to the handle end. It’s hard to tell if the threads are square or acme. I used to run screw machine in the 70’s and ran across this issue when the cutting oil got low.has anyone seen these markings on a main spindle from a very old vise, the trailing edge has machine marks every quarter turn or so, they are not chips. It doesn’t represent a thread cut on a traditional lathe

Thank you.Condolences to you adn your family on losing your FIL - he had good taste in vises.

I have that same exact vise. Mine was also stuck. I wound up using a big brass drift and a copper hammer to drive the back side of the swivel jaw sideways. I would drive it a little one way and get some oil in there then work it back the other way. I don’t think it went completely free until about the last quarter of the rotation. Take your time and use plenty of oil and it’ll work free. Good luck!I got a hollands 46 recently and was finally able to pop the pin out using the screw jack method I saw here and a little help from the blow torch. Naively I thought as soon as the pin was out the jaw would move but it’s still stuck hard.
Does anyone have suggestions for ways of getting the swivel jaw unstuck once the pins out? I’ve been using penetrating oil too but not the good stuff just liquid wrench and some “safe cracker” I found at work. Of course I’ve been beating on it too. Thanks![]()

I’ll have to try that acetone and atf mixI've been restoring tools for a long time. I was introduced to KROIL some years ago. When I worked as a GE field engineer on steam turbines, we bought KROIL by the 55 gallon drum. KROIL website
If you can find KROIL (not in aerosol) then soak that vise in KROIL for a week or month. Then it most certainly will free up. OBTW, other folks swear by 50-50 mix of acetone and automatic transmission fluid. I've never used that, but I'd give that a try first before KROIL. Good luck and let us know about your plan and if it works!

Yours looks great!It might help to preload some force on that stuck swivel jaw. With the vise assembled, clamp something like a chunk of steel off center between the jaws and crank down on the handle. Then tap sideways on the back edge like you have been doing.
I have dealt with more than one stuck swivel jaw. Lots of penetrating oil, tapping back and forth and you’ll get it freed up. Be patient and don’t break anything. That’s a great old vise.
I have its baby brother. Not so much of a baby at a healthy 76 pounds.

I do like dark green and haven’t done a restoration with that yet so I might go down that path even if it’s not the original
Sounds good to me!

It was an old semi brake drum and the middle section out of a high pressure gas cylinder. It’s topped with some scrap plate I found. The brake drum has a couple of bags of concrete in it as well.That's pretty cool.
That's a very interesting stand!

Hahaha! Why?..... just trying to get by until payday!Cool vises!
But, Bud Ice? Did they bring that back?

I got this for really cheap and my intention was to use the cast iron pedestal for a vise base like you mentioned. Once I saw it in person I started thinking that it would look great in the shop and be a lot of fun to use. They didn’t know if the motor worked and it’s about 75 years old. I have 3 phase 220 so I wired up a plug and gave it a try. It fired up and immediately went to full speed, once off it still turned for a few minutes. I’m going to keep it together and clean it up.Nice Smittty! are you keeping it as a grinder, or getting it for the stand?

No idea how crack got there I found it like thatWas that crack from over tightening or pounding? Those quazi anvil spots on vices are perplexing, it’s like the manufacturer doesn’t want you pounding on their product because they can’t control the limits of scale that could be applied in regards to a hammer. Yet they will put something there that invites the user to think “hey I can pound on stuff here”. Some are robust steel and others are just completely bogus machined flat cast iron surface less then a 1/4 thick. When I was a kid my dad and I popped a hole right though one of those machined surfaces on one he had bought at a “TOOLS” tent set up in a parking lot back in the early seventies.
Looks like this Lewis found upthread at first glanceCan anyone tell me anything about this? I can’t read any of the markings. It’s cracked on top. Is it worth anything in this condition?
