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.
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.
