Birch Grove's boiler repairs

The stay knobbling has reached the stage where all those on the outside of the throatplate and the backplate have been done, and a few of the inside ends. [Click on the image for full-size picture.] [View of the boiler]
[View of the firebox crown] This picture shows the firebox crown, looking directly down the left side; the bracket in the centre bolts to the left tank (and shows evidence of a number of different fixings in the past). The washout-plug pad on the left was removed to change wasted nuts and studs. The bright rings lower down are the holes for the crown stays.
A crown-stay hole, showing how our contract boilersmiths are re-making the holes by building up the inside of the hole with arc-welding, which will be reamed out and re-tapped to the original size, using a tap which is being made for the job. [View of a firebox crown-stay hole]
[View of the new ashpan under construction] The new ashpan is almost complete.
The new smokebox is almost complete. The door and hinges are the only old parts re-used. [View of the new smokebox under construction]
