March2020 SteamReport

The Management of Sandstone Estates recently decided to invest in the restoration of the Class NGG 16 A Number 155.
The locomotive will be restored to the original condition called the Little Red Devil with the kind assistance of Shaun McMahon especially with regard to the modifications on this locomotive.
The locomotive was shunted out and the boiler was lifted from the engine units. The boiler was taken to Wonder Steam who will do the boiler work needed while the Sandstone Steam team will do the rest of the restoration. Click here to Read the full Steam Report

Work continues apace at Sandstone on the engine units for 155. The frames have been thoroughly cleaned and painting them in red ochre has begun. The bunker of 155 has now joined the front tank in the cleaning line and ready for its first undercoat. Wheels and axle boxes have been cleaned and refurbished. Our gallery shows the various stages and conditions of some of the components.

David Fletcher who designs live steam models for Accucraft visited us some time ago and we assisted him with pictures for the Decauville model. One of the examples is our own “Bathala”. Our picture gallery shows David Fletcher with the full size “Bathala” and some pictures of the smaller version. You can learn more about the

The magnetic particle inspection is now complete and the wall thickness testing complete. No cracks were detected in the tube plates and all wall thicknesses are well within specs bar the two back corners but these are cleared by the engineer for welding up. All the small tubes are now annealed and are ready for swaging (all 152 of them!). Window patches for the damaged smokebox are being fabricated and the hollow stays, part of the GPCS inlet system, have bored out. This was quite a long job as the original weld had spread making them difficult to remove. As a critical part of the GPCS system this job has to be exact. Our picture gallery shows the firebox end tube plate after all the weld seams have been measured, the small tubes after annealing, forming of the smokebox patches and the secondary air inlets during machining to remove them.

Further news on the boiler repairs. The firebox tube plate has been polished ready for the magnetic particle and wall thickness inspection on the 19^th February. The inspection will include both tube plates and all the welded seams inside the firebox, around the hollow stays (for the GPCS) and the wash out plug holes. Our gallery also shows the new tubes being annealed and the condition of the stays in the water space between the inner and outer firebox.
