[Peter Fels & Phoebe Palmer]

Good method Bob.
Please drop the political postscript.
We end up arguing politics instead of smithing otherwise.

   Set the impeller and shaft on 2 level / parallel rails (knife edges best but smooth round rods may work) and see if it rolls to a position with the same fin down.
It should stay in any orientation if it is balanced.

We must reject the idea that every time a law's broken, society
is guilty rather than the lawbreaker. It is time to restore the
American precept that each individual is accountable for his actions.

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.
