After seeing these nifty press-fit
hubs from West Coast Products, we decided on Colson Performa wheels. Since we want 8" diameter for our chassis set-up, it was necessary to add an outboard bearing holder, machined from a readily available Delrin plug. The WCP hub flange is tapped 10-32 thru to suit standard AM or IFI aluminum sprockets, and we are adapting 25 tooth 5mm pitch Gates timing pulleys to transfer power from the chain driven wheel to one on the other end of the chassis. The adapter uses an
AM-0161 bearing hub -- we pop the bearings out and press them into the WCP hub and our adapter to the support the wheel on a 3/8" bolt (dead axle), and press the rest of the '161 into the bored-out Gates pulley. You can see the result in the attached render.
The WCP hub pressed into the 8" Colson nicely with a little effort on our manual arbor.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
