Assembly notes:
a. after removing the insulated wheel from the axle, the splines need to be carefully filed off so the bushing can be fitted. A small drop of glue on the insulator when re-assembling prevents it from moving.
b. For simplicity, the power pickup wires are soldered to the copper bushings.
c. The brass worm gear supplied with the motor can be used to avoid having to press it off. (it 'should' be the same size/pitch as the plastic ones on the parts list)
