Luke:  I use 9 pipe sections spaced with two hack-saw blades as a fealer
gauge. After an hour they are warm, but not hot enough to cause any dammage
to the PVC pipe . I usualy use 7 gap spaces but less when I test at lower
input voltage. I use thumb nuts on the screws to allow quick changes, My
bolts are #6- 32 counter sync bolts in a 1/8" drilled hole mounted from the
inside out so the nuts are on the outside of the PVC pipe, I use sch 40 PVC
which is thick enough to screw my stand off insulators in the thickness of
the end.  The 1/8" holes are large enough for minor gap adjustments. as
neaded. With 1/2" copper pipe my mounting holes are spaced 1" apart around
the outside of the PVC , Larger copper pipe would require larger PVC and
spacing.
