Try for exercise to calculate dimensions & parameters
of a multilayer helical winding assuming:

-9 layers (sheats) of #8 wire

-coil aspect ratio H/D~3

-equal Ldc inductance of the coil in comparation
 with the inductance of the given classical coil^^


I seem to be ariving at figures much more acceptable
for a low frequency TC garage unit.
At side note ,I wonder if anybody ever tryed
constructing  secondaries in such fashion by a winding
machine,in a purpose for a spark output test
comparation with usual TC designs.

Take care,
Boris
