My CBN wheels arrived today. I ordered them before reading about possible problems with installation, so I wondered if I was going to have to order more stuff. I took the guards off my Chinese Dayton grinder, popped the new wheels in, reinstalled the guards, and fired the grinder up. As far as I can tell, there are no issues at all. The wheels fit in the guards just fine, and although I haven't used a dial indicator yet, they seem to run true.
Hoping for the best.
I believe my old white wheels were 60 and 100-something grit. I went for a 180-grit Mega Square wheel and a 600-grit 4-in-1 wheel from Woodturner's Wonders. I have a Millers Falls plane I bought not long ago, and it needed to have the bevel fixed up. The 180-grit wheel looked scary, so I tried the 600 wheel.
I have never used CBN before. It cuts so fast at 3600 RPM, I'm wondering if 600 is too coarse. It blew through the job in a hurry, re-shaping the whole bevel. The iron never even got warm, so I guess I can forget about blue bevels. I had some glitches because I didn't know what I was doing, but in the end I came out with something ready to be finished on a flat stone.
I ground the iron semi-freehand. I used a rest to establish the angle, but I didn't hold the iron in a fixture. I'm wondering...is this a good idea? The bevel I ended up with looked uniform, and it had a natural camber to it. Maybe 5-10 thousandths per side. If I could continue doing without gadgetry, it would be nice.
These wheels are paradigm-changing. The people who recommend them are right. It's great to focus on the job instead of struggling to develop the skill to use old-fashioned wheels.
