One result of lock-down: in the metal completion of this Pannier. Yes, it is 4mm 00 gauge and, having been acquired as a part-completed model in need of finishing has sat unfinished on the shelf for a long time; I completed making and fitting the lamp brackets and the handrails about 04.00 hrs Sunday morning - all those years in BR signal-boxes on night shift turned me into a night owl.
The original construction of the model is very good, especially the chassis which has clearly been put together by someone skilled in the art of true alignment. A Keyser motor with a long tail protruding into the cab originally powered the model, I suspect the plan was to fit a flywheel on the shaft, but I preferred not to have this intrusion into the cab, and swapped the Keyser for another similar Keyser with the tail already removed, leaving the cab pretty much clear. The electrical pick-up arrangement was rather novel and looked like a piece of trellis fencing, designed to provide springing to the wheel contact; unfortunately this did not make sufficient reliable contact, and so I scrapped the existing pick-up arrangement and created the arrangement in the last photo below, which is self-explanatory if you study the score marks creating isolation sections in the copper clad; it had to accommodate the existing wiring arrangement, apart from my addition of a television suppressor which was quite tight due to the surprising lack of space inside the boiler; incidentally, the bare white-metal interior of the boiler I insulated with two thick coats of ladies' clear nail varnish. The mechanism was run-in on a rolling road and, after a bit of teething, adjusting the angle of attack made by the worm drive, the mechanism suddenly blossomed into a nicely running unit, albeit with still a bit newness to wear off; however, the chassis runs very nicely and reliably, thanks to that accurate alignment.
She isn't a perfect build, and that is fine by me, for I always maintain as much as possible of the original work in recognition of the unknown soul who built her, aware that in many cases these unfinished builds that come onto the market are often the result of someone's passing. The task of priming and painting remains, and for that she will have to join the queue for the paint shop.
