We are using pulley stock and turning the end down to make our own pulley/hub that will press-fit into the Colson wheel. All the sheet metal is .100" aluminum.

The Colson wheels are the standard 4" diameter, 1.5" width. The pulleys press-fitted into the wheels are 28 tooth, 5mm pitch, GT2 profile pulleys, and the ones on the output shafts are 20 tooth.

You can see here the full wheel assembly with the hub, wheel and 3/8" flanged bearings, and on the right is the pulley hub that is machined from pulley stock.
