Work continued on and around the leading engine unit in preparation of lowering the tank into position. The main steam pipe from the boiler cradle to the steam cylinders was fitted with surprising ease. This included lapping of the two steam tight lens rings and fitting 12x 7/8” BSW bolts. While in this area the opportunity was taken to fit the reverser reach rod with its patented designed Beyer Peacock universal joints. Ian continued to fit and test the lube lines for the right hand leading lubricator.
Malcolm and his daughter had a go at cleaning out the residual mess of grease and grime from where the stoker trough was once fitted. It seems that the grease points that are situated outside of this area were never checked to see if the lines were actually delivering the grease where it was designed to go. The end result was years of congealed grease mixed with coal dust forming great lumps of crud. They also had a go at applying some long over due grey primer to the top deck above the hind water tank.
David continued with the rebuild of the crinoline bands that will support the fitting of the boiler cladding sheet metal. The boiler now sports several horizontal string lines that will help align the boiler bands correctly. The myriad of counter sunk screws that hold all of the bands in place have had to be rebuilt as many of the tapped holes had rusted out. As the bands are only ¼” thick a new nut has been welded into place under each side to make up for the poor thread.
During recent weeks, Alan has also been working to remove the life expired electrical cables from their conduits all over the loco. The insulation has hardened from years of exposure to the heat of a steam engine, and likely also from the temperature extremes from years of outside storage in Canberra. As such, all the wiring on the loco will be replaced, in some cases with new technology to help us work safely into the future. You can see from some of the pictures just how bad some of the wiring is.
