BaneBots 42mm Gearbox Pinion

[Gary Bonner]

Does anyone know the specs & a source for the motor pinion to fit the BaneBots 42mm gearbox (with 4:1 first stage)? BaneBots is out of stock & doesn't know when they'll be getting more in.

I have one in my hand right now.

It is almost certainly a 15T .6 module, 20deg pressure angle gear.

One source is the banebots transmission itself. You can buy a motor/gearbox and pull the pinion from the motor. In fact, you can get many many pinions from one gearbox because the sun is the same as the planets on a 4:1 planetary stage. AND the carrier pins are 3mm which means you can open the hole up to match the FP or BB motor shaft.

I just tried the usual suspects for other places to buy metric gears have failed me (WMBerg, Stock Drive Products & Pic Design). I think you are stuck with buying a gearbox and stealing the parts.
