  Awesome, way to go.

Hi Art,
Your suggestion worked perfectly - I have made a stand-off from the planetary and then a bridge on the stand-offs and finally using the centering gear was able to drill the bridge and use an arbor and get a non-wobbling rotation of the planetary.

Hi Art,
I tried your suggestion and it works beautifully - there is still a couple of steps to get what I want. But I thought I'd post this for now.

I'll post the final when I get it done

That sounds good I?ll try that

Hi:

Hmm, to ensure its perfect you could always generate the planetary, and a gear of the same mos/tooth cnt thats 1/2 the thickness. The gear will fit inside the planetary, push it in and bond it.

That gives you a planetary with a shaft in the center and enough room for a planet gear..

Just one way..

Hi Art
You got it!

It?s trying to ensure that the planetary is ?perfectly? aligned with its shaft. Eliminate any wobble.
Then the large gear powers the pinion.

I cant quite picture it, do you mean you want a planetary gear with perhaps its back closed in so a shaft can be on it in the center, and then a planet on another shaft going off to another
level?

Hi Art
I?m puzzling on how to get a planetary working off a shaft. I would like to have a planetary gear with an arbor and pivot on one plate of a clock and a pinion above it from the other plate.

Essentially I want a ?spider? and ?spacer? to mount the planetary that would make the teeth clear on the inside of the planetary so that a pinion can be clear of the spider.  (This is really hard to describe). Any way can you think of a way to mount the planetary on a spider so that the gear will run true on its shaft.?
