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
Don N8ECH
