Of course. He too retains the divine right of every 'merican to state his opinion publicly and with authority, confused or otherwise.
I always thought a "fixture" was the old guy who had been there forever and would probably never retire. I avoided that label by graciously retiring (long time ago) at age 56. :-) Now you'll have to excuse me, my Lovely Bride has just put a warm peach/blueberry pie on a rotatable fixture stationary jig platter stand thingy and I'm on a quest to find an appropriate cutting tool. I decree it an emergency. Blueberry time is just once a year here at the Farm and it is my duty to embrace it.

I don't have a Jet but my "collection" of 5 grinders does include the 1/2 Hp Rikon. It is ok but the construction is a bit cheap. I and others have noticed the irregular casting requiring some grinding or other effort for it to sit flat. I think the 1/2 Hp is underpowered compared to the no-name 3/4 Hp grinder next to it, the one Woodcraft used to sell for about $100. The Rikon is slower to start up and some people have noted that two heavy steel CBN wheels are almost too much for it.
We also have one at a shop for teaching children and with conventional wheels it spins ok, but horribly out of balance with the Aluminium Oxide wheels that came on it, even after truing. It shakes the whole table. The wheels wobble from side to side and are evidently not entirely uniform as well. When I use standard wheels I use the Norton 3x along with the Oneway balancer - runs so smooth. CBN wheels should be smooth from the start, assuming the seat and nut are true.
Used Baldor grinders around here are usually very high, even with 3-phase motors. With a VFD one would make a wonderful variable speed grinder.

As far as a particular grinder having enough oomph to spin CBN wheels, remember -- there are aluminum CBNs that are much lighter but (I've been told by those who use them) just as good. Ken Rizza sells them, and also has 2-part washer sets that solve run-out problems created by the grinder nuts not being square. I got my wheel last week, and am pretty much in 7th Heaven. They cost much less than the steel wheels also. If you can afford a pair, go for it! at $249 + shipping, it's a good deal.
Wood, and then some more wood.
