[TowerTalk] Frozen Rotor

Here's a couple more ideas:

I use a rubber boot called a "FERNCO" which is available in many sizes wherever plumbing products 
are sold. I got mine at Home Deep-o. They're used to adapt from one size pipe to another, and 
they're made of pretty tough stuff.  Get one that is the size of your mast on one end and large 
enough on the other end to clear the OD of your sleeve. Mount it with an SS hose clamp to the mast, 
just above the sleeve. You can slit it down one side and get it on that way, then clean the rubber 
with alchohol and seal the slit with RTV silicone rubber.  It will keep out the rain.

Between the sleeve and the mast, I use a fhin piece of polyethylene sheet cut from one of the new 
"disposable" cutting boards they sell in Walmart and supermarkets. To prevent wear, I wrap it around 
the mast and cut it so it doesn't overlap, then slide it in between the mast and the sleeve to act 
as a bearing. I checked it after a year and there was no noticeable wear.
