I might go to the CBN wheels once course and one fine. Since
those really run true.

The best price on cbn wheels is at woodturnerswonders.com a pair of 8x
1.5 wheels is $250. Other places want around $200 each. Another
advantage to cbn wheels, is that you can remove the guards on your
grinder, since steel wheels don't explode. Thus using 1.5" wide wheels
instead of 1" wide wheels, The only disadvantage, is that you can't
grind any non hardened steel. No bolts, no angle iron, etc.

Thanks.

I think these wheels are aluminum with cbn applied.
