This is probably true. The ID of the bearings on the AM wheels are 5/8", so if we wanted to make it smaller we'd have to use a hub.

As it is, on the center wheel assembly there's a copper bushing (to decrease the 5/8" ID to 1/2"), the wheel, the sprocket, and a keyed hub to drive the whole thing. With this current design, I wasn't able to fit in two sprockets on the wheel assembly and have it all still fit on the extended output shaft of the gearbox. I suppose I could look around for other wheels that aren't as wide and it might kill two birds with one stone - the IFI ones might do the trick.

I'm not familiar with adding flanges, and I don't know if we have the capability of machining it. If we used 1/8" or 3/16" aluminum, would it be necessary to add flanges to ensure rigidity in the frame? If so, what size would they need to be?
