The boiler cradle is a different matter. The vacuum brake cylinders and all the associated components have been removed, and a new air brake system has been designed (below). A new cross member supports 3 brake shafts, one for each air brake cylinder and one actuated by the handbrake shaft. Two new main reservoirs have been manufactured, and design is complete for two auxiliary reservoirs to be fabricated.
Above, final riveting of one of the boiler cradle stretchers into place. Note the gas torch and hearth for heating the rivets before they are pushed into the holes with tongs and riveted over.
Below, the rear tie bar bracket has been attached following the machining of the fitted bolts. The tie bars and nuts have been manufactured, ready for installation at the next workshop day.
