--Previous Message-- Well, I wanna NST and I am going to check around for one, unfortunately I live in the middle of nowhere, where old cars are much more plentiful than NSTs... where could I get an OBIT, are those easy to come by, and out of what? an old oil furnace, I suppose, but anywhere else? As for the wire, does #26 or #28 make a big difference? I just figured i'd be less likely to break #26, and it would allow for more power later on down the road >:} A beer bottle cap is sounding like my best bet. Would it be better to use several smaller bottles or a few big jars? I have several large pickle jars (a gallon or so apiece) sitting around. Is there a certain height-to-diameter ratio that works best for secondaries? =Rockinriley14=
: Acrylic or PVC are both excellent coil form materials, and while a
: 3" x 15" secondary would be great for an NST powered coil, you
: may be underpowered if you try driving it from an ignition coil.
: I'd suggest a 13" long closewound winding of #28 AWG, leaving an
: inch free on each end of the form. This will give you about 900 turns. A
: flat spiral primary is also a good choice. Any good sized hardware store
: will carry incandescent lamp dimmers - these are generally no more than
: $4 - $7 apiece. However, the inductance of your ignition coil and the
: low resistance of your series heating element may be combining to
: overload common dimmers, so the new one may also fail. You probably
: should look for an inexpensive 7.5 - 12 kV NST instead, since it will be
: much easier to charge the beer bottle caps. You'll probably need at
: least a six-pack, or more, to bring your system into tune. And, if you
: can put the bottles in salt water you will increase the capacitance
: somewhat since you'll be eliminating the air space between the outer
: foil and glass. Sounds like you are off to a good start - keep us posted
: on your progress!
