I ordered 10 wheels yesterday. A mix of colors. That ought to last me for a long time. I'm using the last black rock I had bought from WM now. I think I bought it 5 years ago or more. Do they even sell them any more?

YH- I've always used the 3/8" thick rock. I just went to Cook's website and it appears that the only size Ruby they have is the 1/4" thick rock. That's 1/8" thinner than what I'm used to. Is that what you normally use?  Just make an extra pass or two and extending the pushing "fork" further to compensate for the 1/8" loss in thickness? Shouldn't matter, right?

I had always used a 1/4" rock before my last order and have never been able to get the proper profile. I switched to 3/8" rocks this last order and will never use a 1/4" again. Finally for the first time in all the years I have sharpened my own blades I'm getting the correct profile.

Do you dress the ruby colored stones the same way as the blue ones?

For now I have only used the black 3/8 stone because I had a lot of blades I wanted to re-profile but I will dress the stones the same regardless of the color.

Its important to dress each stone exactly to the same working profile.  Once I had one correct, I would push the edge into a light piece of metal deep onto the stone, and real time cut the profile into the metal, much like making a master key.  From then on, all I had to do to check was slide the gauge of the wheel to check.

The ruby stones hold their profile much longer, getting a more predictable and consistent blade to blade profile.  This also makes successive sharpening easier.

My question about dressing the ruby stone wasn't clear. Do you use the same dressing stone to dress the ruby as you do the blue stone?

I'm not sure Bob, but I would think that it wouldn't make any difference what you used to dress the wheel with as long as it got dressed!

Yes.  No problem.

Can't bring myself to call them rocks sounds so crude, they are grinding wheels or just wheels for short. I use the ceramic blue or the reds interchangeably and really can't tell the difference. Both seem to last forever. Probably shouldn't say this but once I shape a new wheel I seldom retouch it and when I do I use a diamond grit dresser. Frank C.
