I have been trying to grind primary bevels on plane blades using
Silicon Carbide bench stones - primarily a coarse Norton Crystolon
stone. I did one primary bevel using a 700 grit Silicon Carbide (I
think) water stone.
The results of the grinding tests to date are here

The comparison of the wear on the oil stone versus the water stone is
here

I have not yet found an alternative to my bench grinder.
