Mill winch

Loopy, could you just mount a roller/pulley arrangement on top with a counter weight(bricks or a 50kg sack of cement or something) to take off the load for easier travel?

What I don't like about using a motor is the inaccuracy of lowering the drill to the work piece usually due to the inertia of the motor.

I had thought of a counter weight, and that might be better also for installing a smaller motor. Maybe a windscreen wiper motor might do if rigged that way.
I don't have to worry too much about where the motor stops because any accurate vertical travel will be handled by the quill feed.
