Hmm, that's like as not... don't have my brass magnet to figure it out
though.  Wonder what would be a backyard way of determining such?

 You sure you have copper and not red brass?

 I once bought a piece of ca. 4", heavy gauge "copper" pipe from the
 scrap guy.  Split it, unrolled it and made an omelet pan.  Jeeez, it
 all went hard.  Annealing didn't seem to do any where near as much
 good as it should.  I eventually learned that it was red brass.
 *Looked* like copper but it sure was tougher stuff.

 Nice omelet pan in the end, though.

 To cut copper or brass that thick, I'd try to go with a band saw.  (Is
 that waht a "sawzall" is?  Hand held band saw?)  Slow speed.  I cut
 out a piece of naval bronze for an air hammer part on my little cutoff
 bandsaw (set upright with a table mounted).  Slow but went pretty
 good.

 The Beverly B3 is great but I don't know how you avoid distorting the
 off-cut workpiece (if that matters.)
