[TowerTalk] Pinning my mast in rotator clamp

[mrlogs]

Hi All..
  My Yaesu G-1000DXA manual say's to drill thru the mast & put a bolt thru the rotator & mast to keep it (the mast) from turning in the clamp. I was told to do a survey here & get everyone's input on doing this as it might be a bad idea..
                         Thanks for your input!
