I certainly can’t offer “good” advice!!!
Just an opinion, from a newbie turner.

As far as needing two wheels to get a sharp edge….

With the two wheel grinding/sharpening system….
The first/course wheel, is used for initially “shaping” of the turning tool and establishing the bevel angle.
This is usually done only once, when the tool is new.
Unless, of course, you experiment/decide to change it’s shape or bevel angle.

The second/fine wheel is the one that “sharpens” the tool (once the shape/bevel have been established).
Sooooo, IMHO you don’t need “the set” to sharpen your tools.

As far as the grinder being unbalanced….
I wouldn’t think it would be detrimental to have different types of wheels.
Look at some grinder setups…
There is a wire wheel or buffing wheel on one arbor and a standard grinding wheel on the other arbor.
Now then, I do know that the CBN wheel is considerably heavier….
Soooo, that may just make me wrong!!!

Others, with more experience and expertise, will soon be along to offer there advice….

Jeff, I’ve been using an 80 grit diamond lapidary wheel for sharpining my tools for about a year now. The results are I do get a very sharp edge with 80 grit, but the edge breaks down rapidly BECAUSE I’m using diamond instead of CBN.
So, I looked into the CBN wheels, and found most are made in China. After that revelation, I went online, and am in the process of ordering some at 80 and 180 grits with 5/8” center hole. My club president indicated if I could get enough interest, our club, SAZWA, will make the purchase and sell them to our members for the same cost paid to China per wheel, shipping included. Cost per wheel shipped to Tucson is $108.80 each. If you want to wait and get in on a wheel or 2, let me know. The wheels I’m ordering are 8” x 1.5” x 1/8” radius with 5/8” center hole. We are doing this to save ourselves a few bucks. We are not making any profit as the club cannot operate that way. You would pay any additional shipping from Tucson. If interested, send me a pm. Also, I cannot offer a warrantee as the vendors do. I will check with the supplier about their warrantee.
Since I checked into this, through Alibaba. com, I’m taking a wild guess that these wheels that are currently being sold by already known vendors might be made by the same manufacturer I’ve been in contact with. My conclusion is based on the fact that of the 25 + other manufacturers that responded to my inquirey don’t have CBN in their product line… Jerry (in Tucson)

I do not have a CBN wheel but sure would like one but to much money. I have used one and they are wonderful to use.
Me personally if I did get one I would still have a 60g white wheel for reshaping a new gouge.

The one time I did use the CBN it was wonderful sharp and I and the vets I teach sure would like all the tools that cut so sweetly.

I have two woodturnerswonders wheels and love them. Both are right behind my lathe on a cheap Wen slow speed grinder but work wonderful so far. I turn a lot of canes for the Welcome Home Montrose honor canes for Veterans and my tools are razor sharp. Our club, is really involved in civic projects. Keep the faith.
