The cab mockup reduced to a flat-pack, ready for assembly onto the loco. Materials were also provided for the roof, to be fitted after final assembly.
The cab sides and ends assembled onto the loco. This gives a good idea of the revised proportions of the cab to suit the FR loading gauge: we have attempted to retain the original character in something slightly smaller than our loco's original cab.

Erle and Dave gradually increase the air supply to the turbogenerator, monitoring the voltage and rpm while the lamps get brighter.
At 3000rpm, the turbogenerator was producing the rated 50V. This was with a relatively small electrical load and powered by air at around 100psi. We will put together a higher-rated load bank next time.

The first glimmer of light from the turbogenerator. After all Erle's careful work on the mechanical side, and the outsourced electrical attention, it does actually work!

Using the laser to mark a circle on the target plate. The laser itself was attached to a rod accurately centred in the cylinder bore, which was rotated to produce the circle.
