I water-jetted two 15" X 2.5" discs of plexi and mounted them on a "lasy susan" bearing

I am wrapping the form with two layers of polycarbonate film and bonding it with coil dope (Dolph AC-43).

Wire spool rides on a flat roller thrust bearing, 8" x 5/8" bolt, and 5/8 retainer

Once the coil is doped and given time to harden, the disc forms can be removed and the excess polycarbonate can be trimmed from the coil

This creates a ultra thin former / coil with a much lower self capacitance than winding on 15" pvc ( which is not really 15" )
