I USE 8 PC OF 1/2 IN COPPER PIPE WITH A 1/8 IN HOLE IN THE CENTER OF EACH 3
IN PIECE. I THEN TAKE A 5 IN PIECE OF 3 IN PVC AND DRILL A 1/8 IN HOLE EVERY
1 IN AROUND THE CENTER CIRCUMFERENCE. I THEN BOLT EACH INSIDE the PVC with 1
in 6-23 bolts. I us  a hacksaw blade as a spacer. I use 1-1/4 in bolts for
the last place on each end to make a wire connection. I mount the PVC end
wise on 1 in spacers for air flow. The 6-23 bolts are smaller than 1/8 in to
allow ajustment of the spacing.
