Any idea on what to look for when I take it down and open it up.

What is the way to balance them?

Is there a variable strobe that one can get, mark the blades, and find out
which one is the one that makes the biggest circle?

I've sat here till I'm dizzy pondering the bests approach to this.

BTW, it gets really exciting when the tape gives out and the nickels and
pennies you used for balancing weights go flying. Especially if the fan
is on HI (of course it is on HI)

Best regards, ;-)

I had one like that. I thought that the motor was a goner.
It turns out the the hub was a little loose on the shaft and had slipped
down a little to where it was scrapping on something.
I raised the hub slightly and tightened it and removed a handful of
metal scrapings. It now runs great.

Good explanation. Under AC power the rotor may be sucked up enough to make
something run, cut the AC, rotor falls down a bit and disengage the rubbing.
If this is the case a shim washer should do it.
