Thank you everyone for the help
Hah, we have had a bad experience with JB weld recently. The 4-40 threading of one our fisher price motors got stripped. We dirlled it out and replaced it with 6-32 threading, but there wasn't enough tapped depth to work at all. So we ended up JB-welding it to the andymark planetary gearbox, which worked until it snapped of in Portland. We then replaced the JB weld with more JB weld, and epoxy on the outside, which didn't work at all. Then we put 8-32 bolts in to prevent the motor from spinning around, and proceeded to secure it in place with large amounts of hot glue and zip ties. We subsequently bought a handful of fisherprice motors from ifi, and a new gearbox from andymark, and replaced it all at SVR. (phew)

Back on topic, team 100 originally used globes on their accumulating mechanism (rollers on top and bottom). At portland it was rather slow, so they replaced it at SVR with the banebots motors, (I think with small banebots gearboxes as well). We asked them about it and they said it delivered just as much torque while being twice as fast. They were #1 seed, and went on to win SVR as the competition's best hurdler.
