Thomas Burton Kinraide Reproduction!

29. June 2008 - 81 Years Today Thomas Burton Kinraide died -
We decided to wind a Kinraide Coil as a tribute.  It was an all-day affair,
and well worth the effort.

Endless thanks to Frank Jones who had the special triple silk-covered wire custom made!

Modified Form of Kinraide "Jackson Coil"

Kinraide Reproduction Electrode:
Point / Limitless Plane Electrode

In particular, note the following discharges:
TCFSparks1:  Point is even with the surface of the plane
TCFSparks2:  Point is retracted inside of plane
TCFSparks3:  Point is protruding from plane
Stationary Series Quenched Spark Gap
This gap has no insulting substances to separate the disks.
Mica or bakelite washers used in the early gaps tended to arc
over time and require frequent cleaning or changing.
