I replaced the iron wire with the guitar wire (they're only 99c in
waldons!), and it works great.

Gary, your rig needs some updating - it could do with a spring or something
to keep constant tension as the wire gets slack with heating up etc.

I found ~10-11v @ 1-2A worked well for this set-up. I used the bench power
supply to test it out, although now we know a range any old DC supply
should do.
