So that reminds me of a question I've had for awhile. What's the best
places to get copper plate, and what are the sizes and shapes we should be
looking for? Are there sizes that are more versatile than others? What is
the common ways of securing them in place while welding? Obviously magnets
won't work, so what's best?
