Greatly improved coil, question
John, all-
Thank you for all of your suggestions. I tore up my old 1/4" pipe primary
coil and replaced it today with a flat primary wound tightly with #12 awg
wire, about 26 turns in all. A recent goal of mine was to get the nice
toroid ( 4" drain pipe 4" inner diameter, covered with adhesive al. tape)
that I made in early spring to work with my current coil. I had made the
toroid to function with my coil, but due to poor design of the apparatus it
did not, until recently. I tapped the primary at about 18 or 19 turns, I
forget the exact turn, and I am happy to say that my new record has been set
with a spark length of 16". It is still shy of the 40-42" that I hear is
possible. I am glad that I got the toroid to work however. It took a
couple of seconds for the toroid to emit sparks. Eventually it did, and
every time it discharges it is in that same point. Either that or I use a
wire set on top for a break point. I think the next thing that I might
tackle is making a synchronous rotary gap. The question: What is the
easiest way to tap the #12 stranded insulated wire? What I am currently
doing is driving a nail into it, and wrapping a wire to the nail. It is not
as convenient as the clip I had for the copper pipe, and it is probably not
as precise. Thank you,
