I fear I will have to do something similar to the table screws in my mill. Commercially available nuts are all 10x bigger than the cast iron blocks in there now. I need to design something that puts more threads in the nuts so that the wear rate is more reasonable, while still not taking up any more room vertically. The thought has come that I should buy 2 spares, and use them both, but with the inside one floating on the ends of a pair of cap screws all the way through the one you can see so they can be pushed apart to take up the slack. Cap screws would give an allen head where the existing jack screws are just slotted set screws and damned hard to get a screw driver into them.

I wrote some transmitter remote/ ATS software for the Z-80 but came to the conclusion its architecture was hopelessly broken by its lack of anything like a conditional long branch, so you had to write all your conditionals upside down so the failure then took the next instruction which was the long branch you needed.

Its slightly different, but I actually use an editor I call vim on the coco! Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
