I got a good deal on a used slow speed grinder with the basic Oneway wolverine setup and two aluminum oxide wheels. The grind angle for my current jig is set by adjusting the distance between the tip of the gouge and the jig. I made depth gauges for different grind angles and it is fast and repeatable. Seems that the varigrind uses a fixed distance between the jig and the tip of the tool and the grind angle is set by adjusting extension of the v-arm. What are the options for quickly and repeatably setting the v-arm to different extension distances corresponding to the grind angles I use (assume it will be used with a CBN wheel that will not be reduced in diameter with use)?
My other questions are about CBN wheels. Having used 1" sanding belts for years I understand the advantage of a wide wheel. Some wheels also have abrasive on the edges. What sort of sharpening is done with the edges of the wheel? What are the advantages/disadvantage of rounded transition (radius edge) versus square?
