My team is also using a disc break. We are engaging it with a window motor. I have also seen a few teams use pneumatics to engage it.

Re: Winch problem

Are there any good worm gear transmissions for CIM's? That solves the problem right there.

We built two worm gear transmissions for CIM motors last year. They are pretty simple and as long as your machinists can hold reasonable tolerances they work very well. Far simpler and a bit less fussy than planetary or even spur gear transmissions.

the gear ratio is 70:1

In the Versa Planetary, or is this additional reduction afterwards? 70:1 is above the recommended reduction for using a CIM motor with Versa Planetary gearboxes, per their user guide.
