I'm sure it came off from here but has anybody got any ideas how we get the ****** thing back on!
All of the copper requires annealing to ensure that the pipework is ductile so that the pipes and joints are not stressed when re-assembled to the locomotive. Here the top feed and injector pipe sections are being annealed with a propane/oxygen torch
The pipes are annealed by heating them to a cherry red and then allowing them to air cool. Care is taken not to heat the joints between the copper pipe and brass flanges.
Trial fitting of the firemans side crosshead requires careful scraping to ensure a good fit to the reground slide bars.
One down and one to go!
