I've never had a wheel that ran out, right from the box, so I can't
say how poorly they would true one.


New wheels come with cheap plastic centers so its difficult to get
them mounted concentric in the first place. Might not be a problem
with small wheels but it doesn't take much on a 10 inch wheel to make
the whole grinder vibrate. I think that lead use to be the prefered
material for adapting the large hole in the grinding wheel to the
smaller grinder shaft. Should I replace the cheap plastic spacers
with something better?

I am using the standard flanges and blotters supplied with the wheels.
I did not tighten the wheels very hard because they ususally tighten
themselves up pretty tight. A 1.5HP motor accelerates pretty rapidly
and the 10 inch wheels have a lot of mass so I suspect the motor
tightened them up very tight by now.

I suspect I'm using too much pressure on the dressers and not the
light touch that harold recommends.

This grinder was purchased used and the original 10 inch wheels were
worn down to about 7 inchs. It ran fine with the old wheels.

Perhaps I should remove one wheel to reduce the vibration and dress
the remaining wheel. After I get it running smoothly I can then
add the second wheel and dress it.
