Re: tuning?
Bobby,
Look at the various text files on pupman-dot-com and scan the archives. You
really need to start with the gap closed down small, so it fires at a
low variac setting. Put a discharge bump (or a nail) on the toroid.
Place the primary tap to about half of your primary turns. Switch on
with the variac at minumum, and turn up until the gap fires steadily.
Also, a nearby flourescent tube is useful. You should see the tube light
up a bit and maybe some little sparks off the nail. Switch off, move the
tap one turn inwards. Switch on, if the lamp and sparks are
dimmer/fewer, next time move the tap one turn outwards. If they are
brighter, keep moving inwards. When you seem to reach the maximum, you
can then try doing the same in 1/2 and 1/4 turns. On some coils this
makes very little odds, but on others 1/2 turn can make a big
difference.
When you reach the optimum, you can start to open the gap and increase
the power in. However as the power goes up, you will find you may need
to add around 1 more turn to your tapping point, as the large corona
field reduces the coil's frequency.
Good luck!
Trial and error is the key here as always.
