Homebrew PCBs

The old fashioned soldering Irons had a big piece of copper, pointed to aid soldering, held in an iron shaft, becasue iron transfers heat much slower than copper, pressed into a wooden handle.

Strike while the Iron's hot is what a blacksmith must do to shape and weld iron - only when really hot!!! If the iron cooled down, shaping and welding were impossible....
