Plywood pulleys were cut on the tablesaw for the first stage reduction.

NOTE: In 2009 the belts are replaced with chain. See page six for details.

The suspension design requires these cutouts to mount the springs. They were cutout with a router that had a pivot bearing mounted to it that was positioned in the pivot hole during the cut.

A suspension swingarm mounted to test the fit.

A roadwheel being cut on the tablesaw.

Once a wheel blank is rough cut to shape. It is then slowly pushed into the blade a little ways and then rotated 360 degrees. It is then pushed a little farther and rotated again. This process is repeated until the wheel is perfectly round.

I made a dish cut into the outer roadwheel faces for a somewhat scale look.

The dish cut was made using a jig that lowered the wheel face into the spinning tablesaw blade. Once the wheel is lowered all the way it is rotated 180 degrees to make the dish cut. Note: This tablesaw technique (side cutting) will only work with carbide tipped blades.
