Just wondering why there are no CBN wheels finer than 1200 grit? Is there another alternative that doesn't need truing and won't change diameter?
There are resin-bonded CBN wheels in grits up to 10k. They will change diameter over time, but very slowly and by a very small amount. And of course they are pricey.

Thanks! Just what I was looking for.
Cheaper than diamond and they don't require a water bath
"and they don't require a water bath". The problem with not using a water bath (ideally with an anti corrosion additive) is grinding dust. That's why experienced
dry grinders generally wear dust masks.

There is no "need" for water for either CBN or diamond on a slow speed grinder. The reason that Tormek recommends lube is for dust suppression and longer life.
