I put the gears on order with Topslots 'n' Trains and several days later I had them in my hand. I carefully ran a 2.5 m.m. drill bit through the spur gear (it has a 3/32" dia. hole) to half way from both sides to ensure it would be central. I then mounted it on a Ninco axle and fitted the pinion to the motor.... 'et voila' as they say in France, it all fits beautifully! All that's left now is to take it for a run!! No more buying a front and rear axle set from Mr Ninco!! Stay tuned
