[TowerTalk] AB-577 AB-621 Winch Motor

[Ed G]

Hi Folks,
     Has anyone ever used a small motor to crank the mast up on an AB-577 or
621?  If so, are there any recommendations for a particular motor type or
mfgr?  Seems like it would be easy to couple the motor to the gearbox using
a 1/2 inch shaft and coupling.
