Note that many caster wheels that are described as 2" wide are actually
1 5/8 to 1 3/4. They seem to be 2" wide at the hub and taper a little.
I ended up buying a contact wheel on ebay.

The other potential issue is whether the bearings will hold up at speed.

Are you interested in my not wide enough casters?

Hi,

I've decided to go ahead and use castor wheels on my grinder.
They'll spin around 1700 rpm. I'm told that they might be noisy as
they won't be adquately balanced. So long as I get a smooth wheel (no
spokes), does balancing consist merely of evening the surface? If not,
how do you balance wheels?

Or more urgently, just tell me asap, is it feasible to balance a
castor wheel?

If so, I'll order it now, and then learn how in the days/week or two
before it arrives (multi-tasking! :-) ).

Alternatively, it seems that pulleys ARE balanced, so I can look for
a flat-belt pulley large enough? But the castors are convenient for
several reasons, if they aren't too hard to balance.



thanks!
