[TowerTalk] Fwd: MA40 and T2X rotor off center

[Kim Elmore]

At least my T2X manual says 2 1/16”. It must be right because I use 1/32” shims with my 2” mast and all is perfect. 

Now for an embarrassing admission: I was ignorant of this for nearly 20 years and couldn’t understand why my relatively modest antenna load would regularly chew up my rotator, nor did I understand why, no matter what I did, the rotator would sound like it was binding as it rotated. Once I realized my foolishness, I added the shim and, just like magic, I’ve had no more problems.

>>   I think the reason for the wooble of the rotor output is because the rotor is capable of turning Antenna’s pipes up to a list 2-3/8” in diameter,if one uses 2” pipes,since one of the grips is fixed with the base of the rotor and the other is movable to clamp,the shaft will be off center,unless you shim(3/16”) both sides to make to be centered in this case!
