		The same thing happens when the temperature goes up on
anything..it 
		elongates..on the other hand..when it goes down..the rod
gets tighter..

		This would be true regardless of how well it is
installed/tightened.

	Yes, but, IMHY, that would only occur if the frame were held at a
constant temperature while the rod is cooled or heated. The other
possibility is that the coefficients of thermal expansion for the rods and
the frame are different, but that difference would have to be significant.
