We used this bolt as a cotter pin for the main pivot in our arm. We had a peice of 5/8" shaft through a peiced of steel pipe, and this bolt went through both of them (so that every peice was perpindicular to the others) in order to keep that 5/8" shaft from rotating.
On the 5/8" shaft we had a big 80 tooth #35 sprocket, and the gearbox was on the arm and would sort of climb up the sprocket.
Well, one of our matches we noticed the big sprocket turning (its not supposed to do that) and our arm was dead. We found this peice of metal where the bolt used to be.
Thats a .25" hardened steel rod. It is completely cut in one place, and mangled almost beyond recognition in another place. A Globe motor did this.

TF8Based on your caption, I think your problem has little to do with the globe motor and a whole lot to do with gravity and some serious inertia.
