Kinraide Coil - Moulded in Bondo!

Part 1:  Cast with Bondo!

Secondary placed inside - filled with wax!

Top view.  The smaller reduction at the top was part of the mould I used, I am actually going to cut
this section off.

I use Venetian Red, a very staining color that resembles bakelite as it darkens/dries.

Semi-completed coil.  Requires many gloss coats, and finishing of the ball terminal/socket.
Primary coil fits over the secondary mould.

A few crackles...

Close the spark gap and you get thin violet discharges...


Add another amp of input power and you get some sparks!

Appearance of brush in the dark...
