Workmate Pivot Nut

This is a pivot nut that I designed for my grandfather's, 1970's vintage Black & Decker 200 Workmate. The part number for the original injected-molded part, at least the one I have, is 975878. I've attached a photo that compares the two.

In use the pivot nut screws on the Workmate's vice screw. The sliding portion of the Workmate top then attaches to the pivot nut with a 5/16-inch screw that screws into a nut pressed into the square pass-through.

This was one part of a larger Workmate restoration, which was a humbling, learning-experience, so if you find the part helpful, please comment! And if you don't, well, my best wishes to your own ACME, double-start, pivot nut design and development efforts.

Thanks for stopping by.
