- Cut a piece of wire 3 1/2 inches long to form the axle wheel. Pass the axle through the holes in the gear strut assembly
- Cut out wheels
- Drill a hole in each wheel large enough for wire to pass through and rotate freely
- Drill holes in washers. Holes should be just large enough for wire to pass through snugly. Cut washers out
- Slip wheels and then washers onto axle. Place washers so that the wheels turn freely without wobbling. Attach washers to axle with super glue, being careful not to let the glue run down the axle and onto the wheel
