...How do you get a real tight join between two flat
pieces that you are trying to sweat solder? My book says to just
melt pallions of solder on the first piece and then lay it on top
of the other, but that always seem to leave a few gaps that are
packed with melted flux.
Katherine: Your description of making solder dust and using it is
wonderful - I’ll have to try that. I was also taught, when sweat
soldering, to bevel the edge of the top piece just ever so slightly
and you will never have solder running out from under onto your piece
to ruin it. Also, I was told that after soldering, quench in water
first before putting into pickel. By cooling the piece first, you
avoid drawing the pickle under and into the unsoldered areas in the
event that you have to resolder. Just be sure to neutralize and clean
well before re soldering.
