The underframe has had all the superflous bracketry, clamps and attachments removed followed by a detailed three-stage cleaning programme and then painting. Predominantly the work of one man.

The jacking process is very quick and easy. One of the difficulties of using a donor underframe is that the jacking points are not in the correct place for the 'new' loco. Unable to use the donor lifting points because, well, we'd cut them off to allow the new bogie brake cylinders to fit, we had to use an alternative point. While this is perfectly strong enough and just about in the right place the jack anvil fouled the body tumblehome which necessitated the use of 40mm thick steel packers between the jack and the loco. These only just fitted without fouling the remaining superstructure so they needed careful alignment. In the real work you wouldn't tolerate this but as we're not going to lift the loco often it is an acceptable solution.

With the loco in the air the bogies were rolled under and the loco lowered down again, the photo below shows the loco after the jacks had been removed.
