technique...

I'll side w/ Dave here, Doug...similar experience w/ training for
production work, same technique.

The amount of heating required to heat the pipe to solder-melt point
isn't enough to expand the pipe to the point of constricting the gap
between it and the pipe and it's much easier to ensure both are hot
enough more quickly by adding hit to the pipe initially rather than
relying solely on the (relatively) poor conduction across that same gap
between the two not fully contacting surfaces...

I'm averaging everything I've read here. The practice begins this afternoon,
and it's show time tomorrow. I'll let you all know if the basement's dry, or
if I'm online looking to buy trout to stock my new pond. :-)



Good luck, it really isn't that hard...like most things, people have
their own preferences...

BTW, I intended to point out to the "close up the gap" faction that when
the fitting is heated, it will expand as does the pipe so the
differential expansion is essentially the same between the two mating
pieces--ergo, the gap doesn't actually close.
