I have been using 32' of 4130 mast for 22 years in a Create RC5B-3 rotor
without pinning it. I have never had the mast slip. Antenna load has varied
from 3 Hygain Long Johns with a shorty 40 to the present Force 12 C31, Warc7
and Mag240N.

Subject: [Towertalk] tower mast = to pin OR not to pin
placing chrome moly steel mast
on tower top
It will have a few yagis on it
HOW necessary is it to drill a PIN
thru the mast to insure that it does
not rotate???
Obviously , this might stress the rotor
given high winds - but it is unlikely
the yagis would rotate on the mast
Any comments welcome
