Re: low-cost source for copper tubing?

Have you tried flattening the 1/2" stuff before?  Just
the other day, I was thinking about trying that with
the 1/4" refrigerator stuff.  My fear would be that
the larger-diameter stuff would tend to crack and
break a lot easier than the 1/4" stuff, but that could
be all wrong.  In any case, I'd buy a small length of
it locally and see how well it flattens out before
buying a big roll.
