Hi,

Before taking the boiler apart to work on it; the burner was refurbished and tried out. A bit of a video at:
 


The boiler was removed from its casing and the water tubes and steam pipe were annealed and tided up. The boiler then spent overnight in a citric acid pickle bath to clean it. After the annealing and cleaning it was found that the nipple on the end of the steam pipe had been soft soldered on, so it was removed and a new nipple was made which was hard soldered in place.  As work had been done on the boiler and given its age and a bit battered condition it was decided to do a boiler test. Stuart Turner advertisements stated that the boiler had a working pressure of 30psi, so the test pressure was times 2, which set a pressure at 60psi, well just a tad more which then had to be held for 10 minutes. There were no problems and the boiler was left under pressure to see how much it had dropped by the next day.

Take care Tony.
