Howdy, Need a little advice. Planning about 130 feet of Rohn 45 - 20 to 22 feet of mast - Force 12 Magnum 240N over a Force 12 C31-XR at the top - side mounting another C31-XR. Considering a 2nd thru
Getting two thrust bearings and a rotor aligned to rotate and not bind at some point takes great skill or great luck. If you are putting the second thrust bearing in so it can be run loose and only t
Double Thrusts? Been there, done that more than once ..Rohn 45 Flop-Over and straight-up, old Richfield gas station tower, et al ... never had a problem, just be sure the alignment is correct. Would
