BaneBot gearboxes out of stock...

[Lil' Lavery]

A CIM-sim fed into a CIMPle box will give you a 23.8:1 total reduction, albeit using more space, weight, and significantly more money. Unfortunately, the CIM-sim transmissions are also currently out of stock, but I'd expect AndyMark to get them in sooner than the end of build season than Banebots expects to restock the 5:1 stages.

Has anyone else noticed that Robot Marketplace claims to have the BB gearboxes in stock? We ordered a few yesterday and are hoping they are truly in their stock and ship tomorrow.

Based on BB's failure every year to meet the FRC short lived seasonal demand, it would seem to me that building a slow stock over the rest of the year of typically used parts and reselling them would be a great business model. Hopefully that is what Robot Marketplace has actually done.

We got a call today, apparently Robot Marketplace was out of stock too, their website inventory was inaccurate. I still think stock piling BB gearboxes is a valid business model. If anyone does it, let us know where we can order from next season

But the difference is about 1000 vs 650 RPMS.

If you have old P60s(new style) just get the 16 and then replace one 4 stage with a 5.09 stage from the old P60.

Why don't you order the next higher reduction they have in stock and then remove a stage? Anyone with access to a lathe can do it in about 20 minutes! You dissassemble the gearbox, remove a reduction stage, measure the thickness of the unwanted stage and then remove said thickness from the ring gear. QED!

I can't stress how simple and easy this is!

I think that banebots should a) redesign their output shaft assembly and b) provide all teams two 328:1 gearboxes in the KOP. That way everyone gets some P60s and anybody can remove reduction stages to get the gear ratio they want.

RobotShop claims to have some in stock as well:

Plus some other combinations of them. I just had my facilitator quiz them and they don't have any 20:1 or 81:1 in stock in any flavor, despite the claims on the website. They claim they have the gearboxes but not the motors for some of the motor+gearbox combos, and they're not willing to split up the combo. You're welcome to try to talk sense into them, but I don't need those badly enough to try to force a company to take my money when they so obviously don't want it.

Just make sure you remove the material from the ring-gear on the right end, the grooves still need to be there!
