Re: [TCML] RE: Splicing wires - Secondary Coil

[David Dean <deano@xxxxxxxxxxxxxxxx>]

HI Daniel

This may or may not be applicable, but long time ago when I first discovered the TCML, I wound a
secondary on an old form recycled from a previous coil. This secondary was made from recycled wire
from a solenoid coil and finished with wire from a small motor with a splice about 1/3 up from the 
bottom. This was a small coil 2 3/4" O.D. X 13" form, with only 9" wound for want of more wire. The
coil worked fine on a 9/30 NST and salt water/ beer bottle caps. However the NST did not last very
long, and I happened to luck into a PIG. With the pig ballasted by a welder, and a single blown 
static gap, I put the power to the small coil. It gave fantastic results for a coil it's size, for a
few seconds, then Kaput. It blew the solder right off of the joint where the two parts of the
winding were spliced. It appeared the solder joint got hot enough to melt the solder, then arced at 
that point vaporizing the solder, because there was a blue-green flash at that point when the coil 
died.
