[TowerTalk] How to weather seal a Tailtwister rotor?

[TexasRF@aol.com]

Marshall, even if you were able to weather seal the rotator there is still  
the problem of moisture condensation inside the unit due to the heating/cooling 
 cycle from day to night. The condensation will collect and the same trouble 
will  occur. 
 
The only safe option is to remove the rotator and store it inside where  
there is some humidity control or at least store it right side up so  condensation 
can run out of the unit.

Hello  all,

I have a Tailtwister (TX-2) rotor mounted on a Rohn 25 foldover  tower. 
While the tower itself appears to have survived intact, hurricane  
Katrina snapped the mast and destroyed the antennas.  I need to fold  the 
tower over to work in it, and likely leave it folded over for a fairly  
extended period.  This will leave the top of the tower and the rotor  
upside down.  Unfortunately, it is still the rainy season here, and  the 
last time I needed to do this, rain water got into the rotor and  settled 
in the bell, causing rust and other corrosion damage inside the  rotor, 
because it is only weather protected when it is upright.  I  would like 
to seal the rotor while the tower is folded over to prevent  this from 
happening again, but none of the ideas I've had so far (wrapping  it in 
plastic garbage bags, using duct tape, using sealing foam) are  usable, 
either because they don't seal well enough to keep water out or  because 
sealing stuff may get up inside the rotor where I can't get it  out.

So, does anyone have any suggestions?
