I believe that I can see what is needed now . The cup (as I refer to) is the nut and it is keyed to prevent rotation. The key must have sheared while turning the shaft. The threads are located inside the main shaft and are not viewable with the vise assembled. I have a parts washer that has diesel fuel and I can soak it in that. I remember reading the thread with the electrolysis. At the time I wasn't in need and it made wonderful bedtime reading. I guess I need to review and this time stay awake. Besides, I have several other projects that need freeing-up as well and I could get started on them.

Stay tune for further updates!!

Wow...

That's a mess...

But, it's a Columbian, so it's worth fixing.

In your second picture...that's the tail end of the screw. I'd be rather tempted to find a BIG punch (like maybe an inch across...) and give the end of the screw a few good sharp hits with the punch & a hammer. You don't want to deform it at all, but give the threads a shock. This may break the bond between it & the nut.

Electrolisys isn't going to effect the rust in there. Soaking in diesel may help, but we're talking long term soaking...weeks...

Another option would be to heat up the nut with a torch. Don't get it glowing, just very hot. Then try to turn the screw while the nut is expanded from the heat. Heck, the old candle trick may help once the nut is good & hot.

If all else fails, I'd be inclined to tack-weld the nut to the stationary part of the vise to keep it from turning. (grind off the tacks afterward.)

P.S. Please dispose of that extension cord on the floor. It's buggered & poses a serious electrocution hazzard.

I agree on the extension cord,but I probably have some as bad.Heat and PB blaster may work on the nut also.But i wish I had .25 for all the stuck al diecasting I have removed with the wax trick from dies.

Cutter,

The anvil in the background of your poor little worn- out vise photo looks lonesome. Kindly tag him with my address and deposit him at UPS so they can bring him to my home for wayward anvils.

Every time I spot a break in the insulation on one of my cords, I cut it there & install new ends. Now I have hundreds of 2' extension cords...

I inherited a post vise from my dad three years ago but only got my hands on it in Feb. My uncle kept asking me about it and we finally found out that my youngest brother had it and a pair of heavy duty shears also. I had thought that my uncle was looking for these for himself but when I told him that my brother dropped them off on his way to Norfolk I was told that they were mine. There's no markings on the vise that I could find.

Nobody seems to know what happened to the rest of my dad's shop including the forge w/hand cranked blower, anvil, welder, O/A set-up, and the tools. My mom immediately got rid of everything including the house and cars.

After reading this thread I got up and went out to take these pictures of the vice. The shears were going to take more effort to get out than I wanted to expend right now...maybe tomorrow.

Ron, that one appears to be identical to mine except possibly for the leg length.
Mine has only a faint "35" on the face of it, right about the screw.
I stood it upright for you.

Cutter,
I was thinking that it looked a lot like yours that's what made me take the picture.

I tried standing it up but the laptop must have been tilted a little as the picture kept falling over...

Thanks,
CaptRon

But you gotta admit the doors look better standing up.
