Jim:
	I used 10-24 brass hardware to attach the copper tubes.  Another
thought hit me on this topic.  The PVC tube itself could also be
distorting due to the heating of the copper tubes.  I think I will mike
the 6" I.D. tube and see if the O.D. is way out of round.  Just another
thought, I'll let you know if I find anything of interest.

This is amazing--I've used that expression every "cold" fall, while deer
hunting in northern Wisconsin, but never knew where it came from!
