[VHFcontesting] TT rotor question

[Bill Olson]

Don I use a TailTwister here. It turns a 2" carbon steel mast with the appropriate 1/32" shims. I have a stack of moderate sized VHF Yagis, don't use the thru-bolt and have never had a problem with the mast slipping in the rotor.

Subject: [VHFcontesting] TT rotor question

Along with the new towers here at the new QTH, I've upgraded from Ham 3 to Tailtwister rotors. You might recall that the smaller Ham/CDE rotors had a threaded hole and bolt in the center of the clamping plate to help keep the mast pipe from turning independently of the rotor.

The TT has a hole for a 3/8s ish bolt to "pin" the the mast. I had not done that, thinking it would not be an issue with the larger clamp hardware. We have some pretty good winds here, and the MP does not want to stay put! I do crank on the SS clamps a fair amount, but am concerned about stretching/galling them. We all know what a mess that is, especially 40 feet in the air.

Feedback from TT users and what you experienced are appreciated. Feel free to reply directly if you wish.

TIA
