Work starts to Level the Boiler

Print

Matthew Storey surveys his handiwork - Terry Newman

Updated 11-11-2017. The boiler is being raised at the front to level its position on the rear sliders and to level the tube plate on the new cylinder casting ledge.

The work is being undertaken by Mathew Storey

The boiler was raised with jacks until the boiler was sat in the best position on the rear slides. Measurements were then taken to allow a the new piece of tubeplate to be formed which will be welded into position to make a good fit on the cylinder block. This should be completed on Saturday and should enable a lot of assembly work on the boiler to begin.

However, this was just the start of the struggle to fit the smoke box over the saddle. At the end of the day, the boiler is back on and all the components taken to the workshop. There will be lots of work to do during the comming weeks.
