Re: [TCML] which is more recommended? MOT or NST?
Mot's are great, the low voltage does pose a problem for most gaps,
but with a even barely half decent rotary you can have fantastic
results. Forget about static gaps, but the time you make one capable
of doing what you need for MOTs, you could have built a rotary, I
recommend my setup, two mots (only two, which means you do not need a
ballast for short runs and with a 30A break not at all) about an 80 nf
cap (very small by LTR standards, but it works great for me, due to a
high break rate) and a rotary capable of 700-900 bps. A 6000 rpm dc
motor, with some voltage control, and 8 electrodes will do the trick
nicely, a propeller gap, naturally... With that setup I can crank 60+
inch sparks and they are bright, and angry looking, and the system is
extremely reliable. I can provide greater details, but you could also
just look at my website.
I'd recommend trying them, you will want to hone your rotary building
skills if you ever want serious sparks (like ten foot range) anyway...
