Alright. So it spins really freely but keeping the planetary cluster centred is a bit of an issue. So the attached photo shows roughly (very roughly) what I had in mind.
With the right coupler between the motor and the gear cluster the planetary assembly should stay in the same place. There really isn't any axial load. There is a place for a 40mmx19mm bearing that I happen to have on hand. But what about the driven ring gear? In one of the model shops today I saw a package of 100 5.5mm stainless steel balls they sell for putting into paint bottles to help mix them up. Seemed and ideal size for a bearing race between the two ring gears. Kind of like what Gene H. stated he did on his setup. (Pictures?) So the Blue Gear is fixed. The Green Rotates. The lazy susan like bearing between handles axial pressure in the direction of the blue gear. But really the only thing holding up the green ring gear is the planetary assembly. Say we wanted to mount a face plate or chuck onto the green gear. I'm open to ideas on how to stabilize that. Sketches would be great. Methinks a part that surrounds the blue gear and extends over the green and they also have a bearing race between. Or we make a similar bearing mount to the rear one for the front with the gear cluster holding this in place extended out to the bearing. Now the faceplate is attached to this. But a lot more axial twist on the small bearing in the middle. Thanks John
