BaneBot gearboxes out of stock...

So today when I tried to order the 20:1/26:1 gearboxes [for the 550] today I realized both are out of stock...

After calling banebots and getting no answer, anyone know how long before they get back in stock?

Re: BaneBot gearboxes out of stock...

Banebots will be the only one to answer that question. I can provide some related answers you might be interested in, however. Namely, what other options you have.

Andymark has the GEM500 gearbox 13:1 2-stage, 49:1 3-stage. Or the PG-71 gearbox at 71:1.

From Banebots, you could buy all the P60 parts individually and assemble the thing yourself. It's about $25 more expensive (Crazy, I know). I can post a list of all the necessary parts for a 20:1 or 26:1 gearbox if anyone's interested.

In my search for gearbox alternatives last year, I came across some possibilities that I've yet to try. WARNING: These look like they interface to an RS-500/550 based on the gearbox drawings. I can't guarantee that, nor do I know anything about the robustness or reliability. Most have the motor attached, so you'll need to press the pinion off the shaft or find a new pinion somewhere.

Robot Marketplace PK27 (27:1) (sounds spur gear, less robust)
Robot Marketplace PD27M (27:1) (planetary, more robust)

Also possibilities if you can find somewhere to buy them:
http://www.mfacomodrills.com/gearboxes/942d_series.html
Or any gearbox/motor off this page:

Re: BaneBot gearboxes out of stock...

Ran into the same problem a couple days ago. Those gearbox's are not listed on the FIRST team list of parts. We recalcalculated our need and switched to 775 motors and gearbox's that BB showed available. I would not trust them to get an out of stock order to you in time.

Re: BaneBot gearboxes out of stock...

That brings up another possibility. Order a 775 gearbox plus the correct 550 rear block, mounting kit, and pinion. Still more expensive than ordering exactly the gearbox you need, but a little simpler than ordering all the individual pieces.

Re: BaneBot gearboxes out of stock...

This or a comparable bargain brand drill has approximately the ratio you want and mounts a 550 sized motor. These motor mounts will mount the gearbox. This guide explains how to take apart and modify the drill to lock out the slip clutch.

Angry Re: BaneBot gearboxes out of stock...

Based on the relatively low price of the 32DP gears that Robot Marketplace lists, I suspect that we'll be self-building the three ~26:1 gearboxes we need. We had planned on using several the P60 26:1 but learned of the backorder status earlier today (independant confirmation). Sigh.

Re: BaneBot gearboxes out of stock...

I just got a few 16:1's and plan to reduce them further. Shouldn't be too bad for now until I can get a shipment of 20:1's in.

Re: BaneBot gearboxes out of stock...

This is bad news...
I know of a few of the other solutions but we would really rather not have to go moding drill motors or something.

I hope they get some stock soon..

Re: BaneBot gearboxes out of stock...

An interesting update from BaneBots:
Quote:
PLEASE NOTE: We are currently out of material to manufacture 5:1 P60 planet gears. As a result of this all P60 gearboxes with a 5:1 stage will currently be marked out of stock.

We are having more material made; however, it has a lead time putting general availability of 5:1 gears in the late March / early April time frame.

We are continuing to search for alternative sources of material and believe we have found a few small lots. We hope to make a small number (100 - 200) 5:1 and 26:1 P60 gearboxes available within a week. In the interim we encourage you to look at the 4:1, 16:1, 64:1, and 256:1 P60 gearboxes.
I'll bet that modified drill is looking a whole lot better now, huh?

Re: BaneBot gearboxes out of stock...

Classic Banebots. Will they ever learn that the demand rises hugely during FRC season?

Re: BaneBot gearboxes out of stock...

BaneBots are really mainly BANE

Re: BaneBot gearboxes out of stock...

We have a lot of new, unopened cimulators if anyone needs them down the road.

We also have a surplus of used 4:1s if someone was really in a pinch.

Re: BaneBot gearboxes out of stock...

I don't know your specific application, but wouldn't 16:1 be comparable to those other 2?

This is what we will probably have to do..
But the difference is about 1000 vs 650 RPMS.
