Hi Chris,
Yes that is pretty much it except I keep the jumper on the cap while I
move the tap. I took a long fiberglass rod and attached a piece of
smooshed copper tubing that I bent in a "U" shape to the end of it.
After I power off I lay the open ends of the "U" across the terminals of
the cap and leave it there until I am done touching stuff.

As for tuning I have a long piece of 1 inch PVC that I taped a
fluorescent bulb to one end. I power on the coil and then stick the bulb
near the toroid. As the coil becomes closer to tune the bulb gets
brighter. I start in half turn increments and then quarter then 1/8
until I find a range where it is best/brightest. Also of note is my
spark gap gets noticeably louder as it gets close to tune and really
makes some racket when she is right on. Even a little bit off tune wise
and it just does not have that "BAP BAP BAP" sound. Use a piece of
electrical tape or a marker to keep track of where you have tried the
tap already. I had some trouble keeping track after a zillion tries and
this technique helped me
Try laying a nail on the toroid if you see no breakout(once you have it
in tune). An open end wrench works well too as seen here-

This will help it along if the toroid is too large.

Stay "tuned"

some pics from the construction phase of my first coil....
please tell me what you think

http://home.earthlink-dot-net/~cdowdy2/

notes on pics not at page
the primary outer edge is now elevated 1 inch
I did this by cutting the twisty ties securing end
and then inserting 1 inch spacers putting new twisty ties in

I have placed the power supply on a plastic crate about 5 feet back
I have inplemented the saftey gap there
and plan on winding 2 rf chokes

A question on chokes
my plan is to use 2 x  6 inch pieces of 1"od pvc then wrap 5 inches of
them
with 26 awg magnet wire cap and place between saftey gap and the rest of
tank circuit....

I have 4 rather large caps I salvaged from 2 old ac units.
1 measured 50 uf
1 measured 39
and the other 2 were 8 uf I think
can I possibly use these as filter caps
or are they just good for blasting pieces of flux wire ? a yet untried
experiment...

also can someone write me a quick tutorial on safely discharging caps
and general safe tuning procedure...
I have a feeling ill be doing a lot of tuning.
the design program said 12th turn.... I ll crap a brick should I be that
lucky

kill switch, unplug ,drop caps, then move tuner?

Currently there is just that page but
Im interested in what you think of my first coil
