[TowerTalk] Weight of tower on the main bearing of a rotating tower?

[Richard Thorne]

I'm finishing up the rebuild/refurbish of the parts for a 55g rotating 
tower.

I was pondering and I'm curious.  How much weight will the main bearing 
have to take? It's one thing to add up all of the components on the 
tower but then there's the downward force of the guy wires.

I did some quick math and I'll probably have less than 2500 pounds of 
tower, rotating rings, antennas, coax assembles etc.  I'll be using 1/4" 
guy material which is rated at 6700 lbs and requires 10% tension.  The 
rotating base will be at ground level.

Any idea how much weight the bearing will actually have to take?

Thanks
