[TowerTalk] Capstan Winch

[Richard Elizondo]

Very nice little rig.
These things are a life saver in the big tower world.
I really like the worm gear drive. My cat head is much faster (60-80 FPM) 
but is planetary driven, which can cause backsliding very under heavy loads.

Where did you get that mean looking gearbox ? (Very Nice)
