For some reason, call it a guess or intuition, I think you should check
the shafts to make sure they run true.

The shafts are perfect. I have a 1/10,000 indicator. and they are true.
Otherwise the grinder would have been returned.

They sent me one new wheel last year, but that was crap too. So it's a
low end POC.

The grinder is nothing special. The rests are useless as they attach to
light gauge steel. I have my own rests and might be getting the
Oneways for my gouges. Or making a better set.

wobbly wheels will cause bearing failure.

If they had HF quality wheels, I'd suspect the bearings to fail early
unless changed out.

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.

True, their main use is for sharpening High Speed Steel, and powdered
metal turning tools. They cut faster and cooler, than stone wheels. And
since they never need truing, you can mark the wolverine, or other jigs
for different tools and be able to reset to those markings for repeated
sharpening. When you true stone wheels a couple of times, it decreases
the diameter of the wheel forcing you to change the setting of your jig,
so that you don't change the grind angle on your tools.

Under CBN Wheel 8-inch, 80 grit, 5/8" arbor on the web page it says As
long as the wheels are properly used as intended this should not cause a
problem as they are machined from one solid piece of steel. which is
what I have, but at least some of the others do say they are 6061
aluminum.

The 4 in 1 wheels are plated aluminum, while the regular wheels are
plated steel.

Maybe I am confused. The web page says this..
" These are highly machined 6061 aluminum wheels that are
electroplated with nickel alloy."

Good catch.

How much do these things weigh?

I'm pretty sure all of my grinders are 7/8" shaft.

I use Harbor Freight wheels because they are so cheap and they work almost
as well as the wheels I used to buy at the welding supply store. For the
price a slight sacrifice in life is worth it to me. It's not like they only
last 1/2 as long as a good wheel - I'd guess they give at least 80-85% of
the life. As far as hardness - they work fine and I grind through a lot of
ugly stuff including welds. Never had a problem with wobble at all, and
I've gone through boxes and boxes of them over the years.

Oh crap - you're talking about a bench grinder. Forget what I said. I'm
just not going to delete what I've already written, having put so much great
thought into my response. Though I do curerntly have HF wheels on my bench
grinder and I have no complaints with it either (as long as nobody does
something stupid like grinding aluminum on it...). I only keep one stone
wheel on my bench grinder and a wire wheel on the other side. I need
another bench grinder - more wheels spinning!

Wow - that seems like a restriction that makes those wheels almost
impractical for most use.

it becomes a grinder for High speed steel only.
Which is realy what I want it for.

I use my 1" sander for most mild steel.

I think these wheels are aluminum with cbn applied.
