I find this interesting. I built my stationary gap with 1" Cu tube
sections bolted but not epoxied in place. It has always been
blown/cooled. I gap it to 0.030" and then, later, find that they have
moved;) Some are shorted, some as much as 0.060" apart. I figured that
this was due to not epoxying them in place. It has happened enough
times that I do not beleive it is stress relief any more.
