Here is my completed Primary Coil. It's constructed of 1/4" copper
tubing setting on HDPE spacers. I machined the spacers and clamps
from a HDPE breadboard. The Dollar bill is for size comparison.

Turn to turn spacing is 1/2" on center or 1/4" between windings. The
inside diameter is 9" with an outside diameter of 26".
