[BC] Irons for silver soldering copper strap

[Lane Lindstrom]

I have always has good luck with a Presto "B" tank of acy and a larger torch
tip to do strap or a smaller one for radials, always have used sil-fos (or
as I called it sil-floss). Have a set of small oxy-acy tanks but you have to
be careful not to burn the copper with them. The Presto torch kit did have a
copper iron, but was never able to melt silver solder with it for strap.
