Re: Tesla and Measurements.


Bert,

I have a few minor comments on the optimum primary.  I agree to an extent 
with what you are saying.  What works....works.  This is the maxim magnus of 
experimentation.  Our large number of turns/small capacitance statement 
merely was to tell coilers to break the habitual, monkey see/monkey do 
mindset of Tesla coil building.  Many of our coils responded well to the 
large primary inductances.  The common wisom, however, was against such 
setups.

The botom line is that if one uses a large capacitance, one must have a lot 
of power to plow into same!  Most amateur builders are in the single KW 
range and a .03 is a bit strong or stiff for this.  Again, I am not saying 
that it can't be used.

The terminal capacitance, just like the tank capacitance is purely a 
function of power!  This is really bizarre!  A  .01 capactior in the 
earliest variants of Maggy #11 was giving 96" point to point arcs from the 
large 10X45 toroid, but we had to feed it 3KW of power before the first 6" 
arc broke out!  Another KW beyond this and the 8 footers were there.
The arcs were white and bright, but thin (a function of the small tank 
capacitance).  This whole business is one of synergy and balance, which I 
have harped on since day one back in late 1988.  You can go ridiculous on 
any sizing of components, but to balnace it, you might have to do strange 
stuff at another point in the system to counter-balance.

Naturally a lot of moderates might say why not just hang the fully balanced 
middle of the road!  Fine, but some very interesting and amazing things can 
happen at extremes.  Witness the effect of giant toroids.  First discovered 
by Tesla, then never looked at again.  I am amazed that no one until our 
group in 1990 made terminal capacitances of obscene sizes since Tesla's day. 
 He saw the effect in Colorado, but noted that the pole antenna was a bad 
shape.  This he was planning to correct at wardenclyff!

Bottom line. ..... If if works, don't struggle to fix it!
