Some progress this week; it’s beginning to look a bit like a J10:

The running plate has now received the cab, and with the saddle and the spectacle plate now fixed to the running plate, it is possible to mount the boiler/smokebox/firebox unit in its final position.

For the csb system to work, the body must have a fair weight. The calculations assumed a final weight of 200 grams. Accordingly a ballast weight of 2mm lead sheet was rolled and this is fixed to two tufnol boiler formers and the whole assembly is a push fit into the boiler, with the motor riding in the firebox. With the weight mounted like this it does not act as a heat sink and make any future soldering to the boiler unit a problem.

A few more pics tomorrow if I have time: should be at Wakefield RMS show all day really.
