Meldonmech:

Norman my vice has a 5/8inch screw, and that is what I would use.

Cheers David

NormanV:
The steel facings are now fixed to the jaws, they don't line up perfectly but that will be the first milling job on it when it is finished.
I've found two problems with the "make it up as you go along" method of design.
1) There was not enough space to fit a 5/8" clamping screw so I will have to use 1/2" but I don't think that will be a problem.
2) My choice to use shallow head cap screws to hold the clamps was unworkable as I did not make enough space for those screw heads and the clamping bolts to pass each other. I can't remember why I did not want to use countersunk screws for the clamps but that is what I have had to do.

NormanV:
I've got the holes prepared for the clamping screw. I had originally planned to buy an acme threaded rod for this but have decided to use standard 12mm threaded rod, albeit left hand thread. Where it passes through the fixed end of the main casting I have made the hole oversize so as to avoid any problems with alignment.

Norman,

I have a few 9/16" ACME leadscrews (1/8" pitch) if you would prefer something a bit beefier than M12. I have a right handed one with a very snug fitting nut and a left hand one where the nut is a bit sloppy.

You would be welcome to either as they're just taking up shelf space. (They came out of my Alexander engraver which I converted to CNC using ballscrews.)

Cheers.

Phil.

NormanV:
Phil, that is very kind of you. I would like to take the left hand one, I don't think that a bit of sloppiness on a vice is a problem. Certainly less of a problem than the mental gymnastics trying to remember to turn the vice handle the "wrong" way.
I'll send you a PM.
