Anyone with enough imagination, to see a use for a a TPG in the first place, should have no trouble at all making an adapter plate either to mount this direct on a compound slide, or one that would be held in any of many types of tool post holders.
Do the Trig yerselves, but IIRC, if you set the compound 3 degrees off from being parallel to the spindle, each thou of in-feed on the compound moves the cutter (grinding wheel) one tenth of a thou deeper in feed. This can give you REALLY fine control on depths of cut, if and when you need such.
Where abouts on Vancouver Island? Still kinda want... Don't NEED, but kinda want. LOL!
