RE: First Time Coiler
Original poster: "Lau, Gary" <Gary.Lau@xxxxxx>
Hi Dan:
Some of what you have is useful, and some of it is not.
Any of the ignition transformers (we call them
OBIT's, for Oil Burner Ignition Transformers) or
gaseous tube transformers (we call them NST's,
for Neon Sign Transformers) will be good power
supplies for a coil. The bigger the transformer,
the bigger your sparks will be, so you need to
set your goal. It looks like your NST may be a
12kV 60 mA unit, which is a very nice catch! But
you should check the faceplate to confirm the
voltage and current ratings, and make sure it
works (make sure each HV bushing or wire arcs
equally to the case) before committing to
it. Selecting the power supply should be the
first step in designing a coil, and the rest of
the components follow once the power supply is chosen.
The Powerstat (Variac) is nice too. If you are
able to wire it so it provides 0-140V output
rather than 0-120V, your coil will benefit from a
modest performance boost, but will work fine in either case.
Unfortunately none of the capacitors you
mentioned are useful for a spark gap coil. You
don't need any kind of circuit breaker beyond
what is already installed in your house. I had
written a brief summary of the steps to selecting
coil components - please see http://www.laushaus.com/tesla/howtodesign.htm
