Today's work was to solder up the foundation ring, and make up all the firebox stays. The job was preheated, silver soldered, and pickled for a visual inspection.
Michael H. was flat out making up 2.6 metres of wall, crown, and transverse stays, 69 in total from 1/4" copper rod. Each one was slightly chamfered for easy installation.
The process of silver soldering the stays has commenced.
A few copper test pieces were made for bronze brazing the girder stays. One was done and cut in half revealing no penetration between the pieces despite a good fillet on the sides. The second option has some centre punches on one of the plates to space them apart a few microns so the braze can get in between the plates. Will see how that goes.
No pics from today but will save that for when the stays are soldered up!
Happy steaming!
Nigel
