Sorry about the lack of detail.

The CIM Motor has a 7:1 Vex Planetary Gearbox attached to it facing the front. Hardened steel worm HLVH1 is attached to an 8mm output shaft by a spring pin which connects to a cast iron worm gear CG1042. There's a plate that mounts to the gearbox and also a supporting plate on the other side of the worm to improve rigidity. The worm gear is mounted via spring pin on a 1/4" shaft, which via a rigid set screw coupler connects to a Toughbox mini output shaft (am-2566). a 6" diameter drum supports 1/8" wire rope that goes up to a 3" diameter pulley on the top.

The pulley goes down and then loops around the grabber mechanism (2in pulley diameter) back up to the top, where it has a fixed stopping point.

We put a ton of Red N' Tacky Grease (white lithium grease is on order, we didn't have any) which became Black N' Sketchy when the worm gear ground down. One of the other things we need to improve is that spacing plate, but we know how to fix that issue.

Here are the best photos I have:



I don't have any good photos of the pulley arrangement, but here's a bad sketch of it.
