Ian was driving on the NYMR yesterday, so Bill reports via Ian (yes it's a long reporting chain this time!) that it was a cool fine day at Grosmont yesterday with James Swainston, Nigel Bill, Trevor Wilford, Peter Ellis and Bill himself.
After the usual cups of tea and chat, Trevor and Peter finished off fabricating the heavy duty brackets for supporting the flue for the stove. Holes were drilled in the wall of workshop, brackets fixed, and the flue tube hauled into position using the pull lift. However, there is still more work to do on this project before an initial steam test can be carried out and the stove be brought into service!
On the Q6 itself, the valve setting is due to be done next week, possibly on Tuesday or Wednesday, so, in preparation, both piston valves have been removed and the port widths measured. To facilitate this, the link rod between the steam reverser and the way shaft was removed and the Stephenson link position altered with a crowbar. Some of the small tubes put in the boiler last Saturday were re-positioned to allow Mark O'Brien better access for beading over the screwed copper ferrule when it arrives in the next day or two - it has been waiting for a material certificate before being despatched, but that has now apparently been received so is on its way at last. The chamfering of the flue tube holes has also been completed by the NYMR. The header remains to be removed. Mark O'Brien has been concentrating on the J27 in the last few days, but now his work on that has been largely completed he says he will get on with removing the header on Tuesday.
Nigel Bill removed the defective front safety valve from the J27 and dismantled it. Bill Dobson then measured the clearances on the seat and found it will need machining to correct them.
The next working Party will be on Wednesday, 2 May - fingers crossed, this should be the final month of the overhaul.
