[TowerTalk] Any recommend material to use for a mast drive shaft.

[Eugene Jensen]

The rotator will set in a cage approximately 20 feet from the thrust bearing 
until it drives a 20 ft section of 2" Chrome Molly Mast that will hold 
approximately 30 Sq. ft of antenna's. SC coastal location and could always 
the chance it could see 100+ winds. The basic concept is like a driveshaft 
in a car. Also the design is so we can change out the rotator without moving 
the shaft ass. other than a inch upward to allow the rotor to slide out. 
It's a big project and hope to get into service by summer's end. TX Gene
