[Oblarg]

In light of Jared's hex-sleeve-coupler innovation, I'm currently working on a 2''x1'' tube chassis on which to mount these. The 1/2'' hex shaft from the center wheel will be supported by a press-fit bearing in the side of the 2''x1'' opposite the gearbox, with a hex coupler welded onto the output shaft, completely enclosed inside the tubing.

I'll post a picture when I'm done. It's a miraculously simple solution to what I thought would be a really annoying problem. Thanks to everyone for the ideas.
