Cheap gearboxes (DeWalt and Globe) for Offseason project

[billbo911]

Here is a thread I posted a while back on this subject.
There is some discussion on the use of 775s. I would not be too worried about them now. The manufacturing process has been straightened out and they seem to be fairly reliable now.

In the thread I show how I adapted a Globe transmission to a RS 395 motor. The same approach can be used for 550's and most likely, 775's.

Thanks Billbo911, your thread was one of the reasons I started thinking about modifying something instead of buying a P60.

As I mentioned I was not involved with FIRST when the globe motor was around. Nor was my team. Do you have any idea of a part number or a source of such motors so that I can experiment with them? A quick Google search has turned up tons of hits since Globe is just the company name.

You might try something like this:

These are wheel chair motors/gearboxes that should easily be able to be controlled by FIRST motor controllers.

Wheel chair motors are pretty robust and are often used in Battlebots. (Or at least they used to be used a lot.

DeWalt gearboxes like in the Nothing but Dewalts paper would be cheap and relatively easy to use. I was working on a prototype of adapter the VP input C-colars to use them and the input plates for the Dewalt gearboxes. I never got around to making the custom parts (just 3D printed prototypes so far) or testing it or anything.
