Hate to say it but my experience has been that the water stones cut a lot quicker than an oil stone. I reserve the water stones for chisels and plane irons though, they're too soft for the machine shop.
If your using the round face to the grinder, the honing should only be touching the top and bottom of the hollow to remove the scratches left by the grinder.
Greg,
Water stones are quicker if you have the right grit. Mine are all meant for putting on a keen edge, not for removing metal quickly. You're right about hem being soft though.
My problem is I can't see the details on such a small bit when I'm grinding it. Getting old has it's advantages but one of them is not keen sight.
I'll keep at it. I want to do a test run on some aluminum (aluminium) this weekend so I'd like to get this tool bit ready.
By the way, I'm thinking of making a new nut for the X lead screw but making a new Y lead screw to fit the existing nut since it's in good shape. I think it'll be easier for me to succeed in make a new left hand threaded lead screw than making a new left hand threaded nut. I could be wrong, usually am, but I haven't made up my mind quite yet. I'm going to tackle the X nut first since that's in the worst shape.
