The super heater header was examined for any flaws and found to be in good condition. The last of the fitted bolts were extracted and all of the mounting flanges were cleaned out and assessed. The lapping in of the pilot, drifting and main valves x 4 was completed. All studs where extracted and the holes were tapped out clean to ¾ BSW. The header was turned on its side and the re-machining of the 100 element seats started with the aid of Gavin’s magnetic base drill. The two main reservoirs for the brake system were removed in preparation for and internal examination by our boiler inspector. Some of the support brackets for the steam exhaust lines were also removed for replacement.
Our next workday will be held on the Saturday the 4th of April 2009. The main focus of work will be the boiler cradle.
