Probably will. I added up all the holes and I need about 750. Maybe make a soft jaw for a drill press vise to hold them without damaging the threads. Think I can find an extra thick 1/2" bandsaw blade to make a wider slot?
I've seen a keyway broach affixed to an od holder and was programmed to make a single wipe in the x direction across the face of a threaded plug in a barpull operation before. The lathe spindle was hard to turn when in low gear and the broach would keep the part aligned unlike using a shaping type cutter.
The orange vises look very nice, wish I could justify one for a cnc knee mill.
