The first heating saw the side extension, throat plate, front & side foundation ring soldered into place and the firebox assembly completed. The photos at the bottom show the inspection pictures.
My thanks to Stuart Davidson who is a TSMEE boiler inspector & provided advice along the way as well as doing the silver soldering
I prepared the copper work & flanged the plates, Stuart was not too critical!
Stuart also used these blacksmith grips to reposition the boiler during soldering
The reinforcing plate. The outer holes go right through for roof stays. The central ones are to let solder penetrate.
Drilled for side stays
