I should add that the brake isn't needed for start-stop braking, the
RT21 does than well. It is intended to prevent wind driven oscillations
when not being turned.

IDEA: Auto/truck disc brake, but instead of hydraulic, make it electric....
ramp it closed in parallel to the rotor ramping down.

My 80m 2L beam is destroying rotators (sm PP and Orion 2800). So far no
problems with the beam.
What is happening is any backlash in the gear train leads to rotational
oscillations from the turbulent high wind at my QTH plateau/ridge and
results breaking gear teeth off. The 375# antenna and 100ft elements
provide the momentum/jerk at the stop of movement.
So am looking for designs of a secondary brake I can fit inside Rohn 65
and retrofits to a 3" mast without taking the antenna down and mast out
(big crane work).
Any experiences, products, ideas, designs welcome. My shop is pretty
much able to make anything in metal.
