Homebrew PCBs

You can purchase soldering attachments for some propane or butane
torches. It is a chunk of copper supported by some means in front of
the flame.

I find that I can solder just about everything short of copper pipe
fittings with the largest tip on my 80W station, and everything larger
I solder with a direct flame instead of an iron.

There are also huge electrical irons, like this 550W one
<http://www.ersa-shop.com/images/products/0550MZ.JPG>, and I had one
even larger that looked more like a hatchet than an iron (power
unknown, electrical safety in question due to age so I never tried
it).
