I got a OneWay vari-grind for Christmas and I'm finally getting around to modifying my grinder station to accommodate it. I will be making my own sliding pivot point for the tool, and I can't find much info on how to position it relative to the grinding wheel.
There is a drawing by David Ellsworth showing his setup, with the pivot point being 4" down from center and 7" from the face of the wheel. Is that a good starting point for the varigrind?
Also, there's really nothing written that describes the effects of moving the jig's movable arm. Are there any recommended settings for that, or is it all trial & error?
TIA
