Noobee with Parker vise question

[phubbman]

Hi all.
I'm new here - first post. I've built up my basement shop (mostly woodworking) by rebuilding old machinery. I recently picked up an old Charles Parker vise (mode 383-1/2). It's a swivel base and swivel jaw model, which I'm really glad to have. (see attachment)

This is not the first block of rust I've dragged home, though I've never come across a part so difficult to remove. The tapered pin that holds the swivel jaw parallel to the front jaw (that nub sticking up to the left of the jaws) doesn't want to come out. It should lift right out so that you can swivel the jaw. I tried prying it up from the top - no dice.

I've removed the base and the nut, which allowed me to slip a steel rod through the center hole in the bottom of the casting and into the through hole in an attempt to punch the pin out from the bottom side. After soaking it in penetrating oil for a couple of days with occasional whacks on the steel rod, all I have to show for it is an oily mess and a bent steel punch rod. The tapered pin won't budge. Any suggestions???

Patiently keep up with more oil and daily hammering? Heat it up? I could drop the whole thing in an electrolysis bath???

With all the vise threads on this forum, hopefully someone else has dealt with this. Thanks in advance,
paulh

Welcome Phubbman! I have no special advice but I do like your vise!

Pure and simple patience, persistence and applying pressure by some gradual means seem to be the main ways they've been bested in the past. I think the odd one or two have also ended up drilling them out and making a new pin. Taper joints are one of those things which are great until they get either a burr or a slight bit of surface rust in the mix, and then they could frustrate God himself trying to part them.

I'd be tempted to try heating that and wicking a bit of candle wax in there first off, to try and aid your efforts at removing it.

I would dis-assemble as much as possible, and submerge in the e-bath if you have a setup readily available. That will be your best bet. It's worked well for me in the same exact situation, more than once.

And welcome to the forum, please keep us updated (with many pictures)!

Phubbman,---I have removed a couple of stubborn frozen pins by oil soaking, and heating the body around the pin but avoiding heating the pin itself.---But also what I found on mine was that the pin is not right over the center hole, but is offset to the back and there should be a smaller hole (may be clogged with grease) that you can punch the pin out from.---You still have to go through the center hole, but punch at an angle through the pin hole.---If it is clogged with old grease, you may not even be able to see it.---You just have to dig around till you find it.---Now that you are thoroughly confused, good luck.

Got it last night. I was able to get the swivel jaw separated from the main casting. The pin was still stuck in the jaw, but now i had a much smaller piece to deal with, and the pin was sticking through on both sides. I pressed it out with my bench vise. When it released it really popped.

Everything is all apart now. I'll post the finished product when i get it all back together.

phubbman,
Welcome to the group. I'm jealous of your find. Can you please post pictures of your disassembled swivel jaw? I'd like to see how it compares to my American Scale swivel jaw vise.

Check out my post & the tool I made to get my pin out.

OK,
Here it is disassembled (except for removing the jaws - don't see a need to do that).
Now for the easy part - clean up and paint.

OLD thread bump

i'm actively restoring what appears to be the same exact Parker vise. Anyone know how you'd remove the jaws if you wanted to? It appears they are press fit pins from the bottom and no way to remove them.


while breaking the swivel jaw portion loose i was knocking it side to side with a rubber mallet. Wound up shearing the pins off that jaw inserts - no biggie, but got me curious how you'd remove the jaw insert if you wanted to. appears to me the only option would be drill out the pin, or do what I did and shear them off

The pins have a slight taper to them, smaller on the bottom and larger on the top of the jaw. They won't come out if driven from the wrong direction.

Weld on a stud and use a slide hammer to pull them up.

You guys are likely right. Didn't confirm the taper but after closer inspection they do go thru the jaw entirely
