Hello all, I picked up a Reed 104 vise at a flea market this weekend ($10!) and wanted to take it apart to clean. I tried unscrewing the dynamic jaw all the way, but it is stuck at the very end of the travel and attempting to move it anymore only lifts or lowers the jaw. It cannot move in or out, only a quarter turn either direction. Does anyone have any thoughts on this?

Either A: the end of the slide is mushroomed from being used as an anvil... you may have to try to close it back up and use a file or stone to remove the high metal from the slide.

Or B: some of that crud/**** that is built up inside has got it jammed. Try soaking it in a solvent first to try and soften the crud... then maybe a good penetrating oil.

Or C: a combination of A and B.

I have a Reed 104 that I had to stone the slide to remove it... and I have a Starrett (613, IIRC) that was stuck just from being gummed up with dried grease mixed with who-knows-what. A good soaking made a big difference.

Good luck...

Hopefully it is not A, as it is stuck and I cannot close it. I suspect not because I did not notice any damage on the slide, but maybe it is slight.

Due to that fact that it lifts/drops when I try to move the jaw it makes me think that something is misaligned or crud filled. If it is misaligned maybe the force of being fully extended?

I will soak it over lunch and see what happens. Thanks for the advice.

My 203.5 did that at restore time, it was a combination of A and B, but mostly B. I forget that I used to force the jaws apart, whether a bottle jack, screw jack, but it didn’t take much force.

All good suggestions so far. My only contribution is to remind you that if the threads are still engaged in the nut, that using brute force to further open the slide is bad. Make sure the spindle is out of the nut. The handle should turn freely at that point. Then force the jaws open. A small screw jack will work. Alternatively, if you bolt or clamp the vise down to your bench or something else immoveable, you can use a brass punch or wooden dowel and a hammer to pound on the back end of the slide.

My bet Is that the back end of the slide is slightly deformed. You’ll see fresh scratches once it’s apart. That’s where you can start removing metal using a stone or even fine sandpaper on a sanding block if you aren’t aiming for a museum quality appearance. 😎

BTW, if you don’t have a screw jack or forgot this trick, let me remind you that you can make a shade tree mechanic kind of screw jack from a coupling nut and a long hex head or carriage bolt. Use 2 wrenches and “unscrew” the assembly to lengthen your new “screw jack”

And you can use block if wood to close the gap, but there or four hands may be required.

I'm not a fan of pounding, I prefer slow and steady force, but I am a wimp on vise repair.

Got it out! Not cracking anything was my first priority, knowing now what the hang up was I suspect more leverage on the handle would have gotten the jaw out safely.

I was able to brush in acetone and pick out gunk, around 20min of this and the handle started turning. The back was painted, which I think helped to catch on the gunk.

Does anyone have a suggestion for a good way to clean this? Other than wire brush/dawn/elbow grease? Also, would Boeshield t-9 be a good protective coating? I would prefer to leave it unpainted if possible.

For smaller vises, I have soaked them in a crockpot filled with undiluted Simple Green and then cooked them for a few hours. The old paint just lets go and can easily be washed off under running water or in my case, outside with a relatively low pressure electric pressure washer.
On larger vises I have had some success with warming up the vise and then spraying liberally with EZ Off oven cleaner. Then pressure wash. The advantage of the hot soak in SG is that it also cleans the vise nut and all the inside surfaces. I use those techniques on the cast iron parts…not the handle, screw, and nose.

In most parts of the country, right now you don’t need a crock pot. A dark colored metal bucket full of SG out in direct sun will get warm enough. For several years now, I have been considering building a big insulated box painted black inside and covered with a salvaged double pane window. Put that out in the sun and you’ll get hot solution pretty quickly.

Next time I see a cooler beside the road that fell out of a pickup or ?? I might just grab it for my project.
