I"ve been anticipating this part with some apprehension because it is a critical operation to do precisely right the first time. The slightest error here could corrupt the entire piece and send me back to square one. And it has heartbreakingly happened in the past. It is important that this procedure be conducted with exacting precision. Sodering flux has been applied to the well cleaned surfaces that will make contact, and the bottom and side plates are positioned in perfect proximity to each other and pinned in place on a ceramic block. Higher temperature silver solder chips are arranged along the contact points, and heat is applied incrementally so that the brass parts achieve the melting temperature of the solder but not a temperature that would damage the brass. It is a thrill when the exact flow temperature is achieved and the silver solder is seen flowing to every contact point between the pieces--first left side, then right side.
A little closer view
Now the piece is allowed to cool as we wait to examine the results. It is not my intent to make such a big deal of such a small thing, but silver soldering can be very tricky. I have done it enough times in the past to feel confident about my skill level, but not enough times to think that I am an expert. Every time I hold my breath with hopeful anticipation. Ralph
