Vise Handle

[rossbotics]

Beautiful work Doug! That yoke is primo-extraeligant! Is the broach a snug slip fit to the hex shaft...or could it use a ball detent of some kind. Just thinking it would be easy to turn a groove on the hex and add a prefab ball detent screw (McMaster) to the yoke for $5 would be the cat's meow. Doing the Indian dance...been there done that.

Thanks very much!

I machined the 9/16" hex broach to .585" across the flats of the hex, after hardening it was set up in the tilting dividing fixture and ground to .570" across the flats which gave some wiggle room on the hex of the vises screw and allowed for a couple of sharpening's, it's also ground at a 3° taper to allow for the 1° wobble in the broaching tool and to give the cutter some side clearance as it passes through the hole.
It works very well, here is a photo of the grinding process on the 9/16" broach

Thanks PJs
