This is a complete set of gears and thick spacers for the HANS electric gear clock. They are made from 1/2" MDF.

The centers have a 1/8" pilot hole. You will need to drill the final hole diameter before assembling.

The gears will require some cleanup. IE light sanding or rounding over the edges (as outlined in the book). They may contain small tabs that will need to be cleaned with a razer knife. The rounding over process will also remove the small tabs.

These gears are provide to put you on the fast track to completing the HANS electric gear clock.
