[TowerTalk] Tower mast

[Merlin-7 KI4ILB]

I like the chain thru the side of the shack idea.

 What if, I ran the chain thru some pipe between the gear on the mast and the gear on the steering wheel inside the shack? It could be pvc as long as I support it well at the tower and the holes drilled thru the shack would support that end. Plus that would stop a lot of the problems with the chain being exposed to the weather...An iced up or rusted chain  would really suck!
 Putting the chain in a pipe or tube should do away with any slack that would tend to derail the chain and is very easy and cheap to do.

 Also, it would be easy to make the hardware to attach a sproket to the mast. 
 I was thinking instead of bicycle chains and sprokets useing some 530 motorcycle chain and sprokets. Any mortorcycle repair shop should have some used ones cheap.

Any more ideas?
