Boiler & Burner Test

Enjoyed a nice Sunday lunch and then made up a temporary smokebox with a piece of pipe silver soldered to a flat piece of brass to cap the end. Stuffed the gaps with sheet insulation material to 'seal' it as best i could. Fired it up and despite most (not all, but nearly) of the fittings leaking profusely, the boiler itself was water-tight and the first safety valve lifted off at about 50psi. I have both a large pop valve and an Accucraft valve fitted at present. Pleased with the test and delighted the boiler makes steam ok. Next job - get the chassis running!
