VN 'C' taper tooling being virtually unobtainable on the used market, I'm trying to figure out the best way to go about making or improvising some arbors.
I have a full set of VN 'C' collets up to 3/4", and the nose of the spindle is slotted for a pair of drive dogs to match the original VN horiz. arbors.
I was thinking to make a collar with matching dogs that could be pinned to a suitable horizontal arbor, reduced in diameter and the taper 'adjusted' to the VN spindle. I figure the drive dogs would do the work, w/ no harm to the spindle taper (and/or collet, if say I used the same idea around a collet and straight-shank 3/4" dia. arbor.)
Any thoughts on type of steel (for dogs and collar), heat-treatment, whether to case-harden or not? I do not have a cylindrical grinder, and am but a simple (though decent) mechanic
