[TowerTalk] Pinning my mast in rotator clamp

[Blake Meinecke]

If it were me, I'd pin it.  

My three reasons;  

1) The manual says to;
2) Those aluminum clamps seem fragile, and I'm always afraid of over tightening;
3) I saw an interesting failure of a G-something rotor a couple of years ago that I'd attribute to an unpinned mast.  Continual minuscule back-and-forth mast slippage caused the steel mast to cut a round hole into the top of the aluminum housing of the rotor.  Sawed right through into the guts, causing a catastrophe.  May not happen if you have a TB holding all the weight, but.....

73,

I have never drilled through the mast & bolted.  Have had to climb the 
towers a couple of times in the last 20 years to readjust when we had high 
winds, and the mast slipped a little in the clamps.  I would rather have to 
do this once in awhile than have something break in the rotator.
