I ordered the mega square wheel 180 grit. Call it the Derek Cohen effect.  Big Grin

The all-metal wheels I have are like large heat-sinks. The Spartan wheel does not look like it can function that way. Stick to a tried-and-true metal 180 grit.

I have the 8" Spartan wheel 1000 grit CBN and it works great for turning tools for the last cut.  Ken also told me the 1000 wheel is best for the plane blades and chisels.  Just make sure to get the Self-Aligning Spherical Washer Sets

I was lucky enough that he is letting me make payments for the 1/2 hp Rikon grinder and another CBN wheel.

Received the wheel today and tested it on a beater chisel. Wow oh Wow! this lets you grind the primary bevel in must less time compared to a regular wheel. I forgot to order the special washer set so I am ordering them tonight.

Scoony, so you got the 180 wheel and it cuts that fast?  I was thinking about getting 80 and 220 wheels, and then sharpening on stones.

Yes, the 180 does cut fast and I really don't see the need for anything finer as It is very quick to finish sharpening with stones. The longest part for me was always grinding the primary bevel. Taking a pass or two then dipping in water and repeating. The CBN wheel will get the steel hot, but it takes longer verses standard wheels.

One more voice here:

I, too, have a cheap grinder--it's an old Montgomery Wards 6" grinder that I inherited from my grandfather. I put a blue Norton wheel on it and got myself a Veritas tool rest. The setup works great for establishing a primary bevel and repairing damaged edges. A diamond wheel dresser really helps keep the wheel in great shape. Just wear a dust mask when you use it--dust everywhere! You should, of course, already be wearing eye protection while grinding.

I typically grind my edges almost all the way to the edge, and then finish up on whetstones. I also keep a bucket of water handy, in which I regularly cool the tool as I grind it. Between the frequent quenching and the blue wheel, I haven't burned an edge in a long time now.

Like I said get the 180 and what Kens advise to me is get the 1000 over the 600.  With the grinder and the 1000 wheel it was only $220 with the Spartan wheel.  The 180 for regrinding and the 1000 for touch up sharp.
