Okay, here’s another situation of dumb me.
I bought a used Columbian quick-release woodworking vise on e-Bay a couple years ago. It has been so long now that I can’t remember how it goes together—I didn’t make a drawing, figuring it was so simple I’d remember how to put it back together and use it. But I don’t. Dumb me. I don’t even know if it works for certain, though the seller assured me it did, and that he had been using it without trouble.
The vise’s jaws are about 10×4 inches, heavy gray metal, wooden handle. Opens to a huge depth. It seems like a nice sturdy vise.
The quick-release mechanism consists of a two-part device about 3 1/2 in. long that looks like it goes around the screw threads. I just don’t know where or how.
The larger part has 38007 cast on it. The smaller part has 36006 P 12 on it. The larger part is basically U-shaped, but has five facets on the outside. Its inner surface is smooth and cylindrical. The smaller part is threaded and has two pins on its sides that drop into recesses in the larger casting. As you turn the larger casting around the smaller part flops up and down on these pins. Presumable in one orientation it flops down disengaging from the long gear. Then when it is the other way ‘round and flops inward, it engages the vise’s threads for tightening.
So my questions are—how do I reassemble these parts correctly and how is the vise supposed to operate?
