Electronic – Tesla coil RF line protection

of course you don't want to to remake the secundary coil.

I've made a tesla coil my self three actually before one worked.

What you need is "THE SPREADSHEET"

you can download that file at the bottom of this site: http://home.wtal.de/herbs_teslapage/design.html

then fill everything in what you know and what you have and then just play around with some values of the things you want to change to make it all come out accordingly to your secondary.

Then you can proceed to the most important step where "the magic comes".

Tuning:

-you've to get the primary's oscillation frequency the same as the secondary's resonance frequency -you can achieve this by searching for an ideal point on your primary For this you'l need an oscilloscope and a waveform-generator more information about tuning here: http://www.hvtesla.com/tuning.html

good luck with building your coil!

That is a disaster waiting to happen. Here are just a couple of the problems:

• You can't use galvanized steel bolts for your spark gap. They'll quickly overheat, erode, and the wooden base will probably catch fire. Also, the zinc plating will burn off in a cloud of toxic fumes. Try a Richard Quick gap or a sucker gap.
• You can't use microwave oven capacitors as your primary capacitor. They can't handle the high peak discharge currents and will explode, showering the room with hot oil.
• The hookup wire you've used to interconnect the tank components is too thin.
• The primary (the ~6 turn coil made from copper tubing) is probably tuned incorrectly. You need a movable tap.
• The primary-secondary coupling is too high.
• A single MOT has too low of a voltage. It's not impossible to build a working Tesla coil with a single MOT, but it's quite challenging and from the pictures it is very obvious that you don't have the experience needed.

I am very worried for your safety. You should do more research, starting with this safety guide: http://www.pupman.com/safety.htm You should start off with a different high voltage transformer - a 12 kV, 30 mA neon sign transformer (NST) will be both much safer and easier to get working. MOTs take no prisoners.
