Swapping the motor

	T
he old clumpy motor looked to me as it could need replacement. After some searching I found a suitable coreless motor with 13.000 RPM and two drive shafts.

Fits in between the supports, but I needed to make adapters to make it click into place

Which were duly made. Note the intricate inside on the round adapter which spans the two rings on the non-electrical side of the motor. The adapter on the electrical side was milled flat to prevent shorting out the electric connections

The adapters were glued in place with epoxy.
And lastly the motor was provided with a styrene base that prevented it from turning under load
Well, a trial run showed no substantial improvement in the running characteristics of the loco which meant that the problem lies in the antiquated gearing of the tender drive. Hmm, I don't think if I will do anything about it. As the loco will spend most of its life on a shelf, I will accept my defeat here.
