I have just removed my KT-34A (too far gone to repair), 6' mast, Ham IV
rotator and the section #3 rotator plate from my HDBX-48. I removed the
rotator plate in order to check out the integrity of the 3 mounting tabs
and to make make a place for the pigtail and connector of the new
TailTwister rotator to pass through as well as drilling 2 more mounting
holes for the new rotator.
My question is this: I had a hard time getting the plate out of the
tower (was hitting the cross braces) and had to use some hammer
persuasion. Was I missing something in the removal? I was expecting to
just remove the 3 bolts and wiggle it out. Of course I am up on the
tower while doing this and at 73 my endurance to stand on those cross
braces is not what is used to be. Is there a simpler way to get the
plate back in place? I will be installing a new modified plate and
don't want to hammer on it.
I am replacing the KLM KT-34A with a Optibeam 10-3. 3.5 sq ft more wind
load and a 19' boom vs the 16 on the KLM as well as longer elements. I
have a Rohn TB-3 bearing on the top plate and all rivets looked
good....no sign of torque stress. I live in a relatively protected area
and seldom see any wind in excess of 45-50 mph and that is a rarity. The
tower and beam have been up since 1997 and both were used then. The
tower dates from the early 80's when purchased new by a friend.
Any help on reinstalling the rotor plate without beating it up would be
much appreciated.
73, Dave - W3NP
