[TowerTalk] Chromoly Mast slipping in a T2X rotor

[Richard Smith]

A buddy of mine is using a T2X rotor with a 1 7/8" OD chromoly mast. He has about 13.5 sq ft of antenna surface area attached to the mast, which is well below the rating of 20 sq ft. The T2X is 10' below a thrust bearing.
The mast has been slipping from time to time (windy conditions), and he was wondering if something can be done to stop the slippage. I have been using the K7NV clamp on my Orion 2800's that are clamped to 2" chromoly masts, but I don't see anything on Kurt's website for a T2X.
Has anyone here on the Reflector had a similar experience and come up with a good solution?
Thanks, 73, Rich, N6KT
