[TowerTalk] Add on 3" mast brake?

[Steve Bookout]

How about something like an oil filter wrench.  Power a solenoid, or 
some such thing, to release the pressure when you want to turn it.  
Maybe another solenoid, with some 'over-center' device to lock it.  
Something like the  brake on a surplus military mast referred to in ham 
circles as a 'rocket launcher'.
