 Robert W. Stephens stands next to his developmental 7 kVA hobby Tesla coil.
This unit stands 107 inches tall and all components required for operation
except the outboard 230V, 23 A. variac are located in the base. Topload is
14-1/2" cross-section x 54" in diameter. The HV resonator is #18 AWG PVC
covered stranded copper wire close wound on a 15 inch green PVC sewer pipe
form coated with Glyptal red varnish. The ends are baffled shut and the
interior is pressurized with dielectric insulating gas to +1.5 PSI. The HDPE
rings are hot glued carefully with no pinholes to the O.D. of the resonator
winding to increase the creepage path over the outside of the resonator.
This treatment completely eliminated troublesome and damaging end-to-end
resonator flashovers from over voltage. Primary is a flat spiral of 1" x
0.100" copper ribbon. Tank cap is 0.12 uF at 40 kV by Maxwell. Fo=80 kHz.
K~=0.20. 4 gap tungsten rotary break @ 400 BPS. Power xfmer 12,000 VRMS.

Stephens' commercial maker of Tesla coils and other H.V. museum/educational
display devices.  Some nicely performing twin coils.  Uses creepage discs on
some of his coils. Has a construction gantry to assemble his big coils.  Not
much construction detail and not active since 1999.
