The main frames are ready for the Fitting Shop.

The kit frames are crude, to say the least. The front area of the kit frames consisted of two pieces of cast whitemetal with slots to take the cylinders; a quite ridiculous design, especially when the rest has been made from milled brass. My replacement version is full-length, of course, and has locating holes for seperate cylinders, with slots to locate the motion bracket, all of which will be made from scratch.

 

I am not going with the gearbox in the previous photo and instead will use an in-line N20 motor/gearbox. This will screw to the gear plate that has been made as part of the frames.

How are you going to arrange the final drive from the N20 to the axle?

 

Edit: answer in part 2!

The 3mm output shaft on the gearbox will have a cut down plastic spur gear on it. The spur gear is a push-fit on the shaft. I will turn a brass carrier for the plastic crown wheel, which will be cross-drilled to take a 12BA screw to hold the carrier to the locomotive axle. There should be space to allow the crown wheel to be disengaged, by loosening the carrier and sliding it out of mesh, so that the locomotive axle can rotate whilst fitting up the motion.
