Jorgenson clamp part replacement?

[BigDaveZJ]

My wife inherited a few Jorgenson clamps from her father recently, but my mother in law didn't keep them in the base shape after my father in law got sick (left them outside . . . .) so now the screw adjusters are completely seized. They've sat in penetrating oil for a while now and now sign of breaking loose. Anywhere to buy parts for these online? I know they're < $20 each, but given the sentimental value of these I would really like to be able to repair what I already have if possible. The model #'s on the clamps are 3724 and 3718, and the part that actually needs to be replaced is 3703. If it comes to it I guess I could just buy a couple new ones and salvage the parts, but that seems a bit silly even given the situation.

Thanks!

Thanks for the link, my Google-Fu must have been lacking tonight. I think by the time I get those parts and pay for shipping it might just be cheaper to go buy a couple new ones and salvage them.

heat & a couple of whacks might help too

That was my next step Cobbler, I'm quite familiar with that process with the adjustable control arms on my Jeeps, basically the same concept on a much larger scale. There is plenty of visible rust on the threads, so if I can break them loose I'm not sure how well they will work anyways.

Get some ATF4 and acetone in 70/30 mix( this stuff is flammable but works extremely well) heat up the part well and where a face shield then spray the part and tap with a ball pien hammer might have to do this a few time but it should work in not could check out the electrolysis thread it might take a while but it would most likely work well
