I guess I just never saw one before. I'll bet you could have field day
running a 3 battery split pos system on each end

Is this design from 2014? Is there a self running machine? Or
are you still testing possibilities?

Hi Mike,

If you go back to the beginning of this thread and take a look at the small 9VDC motors being experimented with, you will get the idea about what is going on here.

Think Left to Right. Voltage comes in via the Left brush and exits via the Right brush on the same side. See UFO's many fine drawings and it will become clear.

Get two small motors and make one dual commutator motor from them. Then, graduate to something like the P56 that Mr. UFO recommends. About any DC motor will do, and commutators aren't expensive. (You need two motors to get end caps and brush rigging.)

I used the long shaft so as to be able to get work from both ends, kinda like a bench grinder.

Your local trade school is a good place to have a longer shaft fabricated and installed if you don't have the tools to do it yourself. (I often get the work done pretty much for free.)
