Re: Banebot 56mm gearbox - double D - RELOADED

Update on the tempered C40-hardness A2 tool steel carriers: We finally got around to re-mounting and testing today. The HS kids enjoyed the opportunity to do wheelies and driving it like crazy in a confined area. After about 5-10 minutes of driving, a sprocket bolt fell off (somebody forgot locktite) and everyone suddenly had to leave instead of fixing it.

I wouldn't call this definitively tested, but they didn't fracture and there is no backlash to be seen right now. More testing to come tomorrow.

Our drivetrain is 1 CIM, 12:1, going to a 6WD. See attached pic.
Funny thing is that it does run smoother and no signs of binding, yet (hopefully never). How much torque does it really take to backlash it and break it?
