I just bought the woodcraft 8" slow speed grinder. I am disappointed,
however in the vibraton and weel wobble.
When I turn the rotate the course wheel 360 the edge of the wheel moves back
and forth by just about 1/16 of an inch. The fine wheel has wobble of a
little more than a 1/32. Those 8-in wheels are heary and of course that
resuts in a fair amount vibration.
I removed both wheels and the grinder runs vibration-free for the most part.
I cant detect and any runout, and the low and high (left/right) spots occur
at the same spot on the wheel, even if I re-orient the wheel of the shaft.
based on this, I'm pretty sure it is the wheel and not a bent shaft.
Although I have not attempted dress the wheels, the seem pretty round, that
is a tool dies not bounce on the surface of the wheel.
What is a reasonable expectation of wobble? Vibration?
solution is probably effective, but fairly pricey.
The white wheels were slightly smudged with dirt, as if they were installed
by someone with dirty hands. I would think that would not normally happen at
a factory. Not that I care about the smudges, but it seems as though it
might be evidence that this was a lemon unit that someone tried to tune up
I inclined to ask Woodcraft to send me new wheels. Should I try dressing the
