[TheForge] A Balancing act

[Steve Bloom]

Greetings all...

I have a large (~18" diameter) Champion blower ("snail" configuration, 
driven by external shaft & motor) that I have been using as a dust/grind 
removal unit for years.  The sound level has gotten to be a concern.  I 
done the easy stuff -- check and align pulleys, grease the pillow 
blocks, tension the belt) - all to no avail.  I suspect the problem is 
out-of-balance fan.  I intend to rip it apart in the next few days and 
try to quiet the beast.  I was wondering if any of you have words of 
wisdom about just how to check the balance and then adjust it.
