[R-390] R-390/URR FanPlate

[Barry Hauser]

Either one -- take your pick.  Simply drill a small hole  in the glass, fill 
with lead beads or sand, depending on state restrictions.

Bend 3 of the pins on the ballast into loops and attach fishing line 
appropriate boy scout slip knots, then wind 3 1/2 turns around the hub of 
the fan.  Tie off free end of the line to a newly installed stainless steel 
boat cleat fastened to the wall with a suitable lag bolts at least 6 inches 
long to allow for threads to clear wall in next room for the nuts.  Allow 
ballast to hang approx. 2 ft below level of receiver but at least 18 inches 
from the floor.  (Use a pulley if necessary to clear any obstructions.)  The 
friction should slow the fan down sufficiently.  If too slow, use some 
neatsfoot oil or talc.  If too fast, increase number of windings.

That'll do it.  yup ..  Or you could use a baseball or playing card and a 
clothespin.  Of course, that doesn't exactly reduce the noise, I guess.  OK, 
then whatcha do is get a 220 volt fan and ....
