Dan: I use 3" x 1/2 copper pipe sections with a 1/8 hole drilled in the
center. 9 each. I use a 5" piece of  3" PVC pipe with 9- 1/8" holes drilled
arround the outsite cercomfrance center every 1". I then mount each copper
pipe section inside the PCV spaced with a hack saw blade with 1-1/4" 6-32
screws and lock nuts . I mount the PVC vertical on 1" spacers for air flow.
I connect to the nut of the first pipe and the eighth pipe as a start. To
change spacing I change tap connections. The 1/8" hole is chosen to allow
adjustment. I use countersinc screw heads to center the screws in the holes.
I use a flat nut in addition to the lock nut on 1, 7,8,9 so I can change
connections on them with out changing my spaceing. I put nuts outside the
PVC  and screws inside.
