Perhaps what you are looking for on the input side of the circuit is a small spark gap on the relay contacts as it opens up and closes?  A solid state circuit will not do that.  But a mechanical contact will...  How about a model T spark coil for input???  It uses a contact that vibrates and pulses the voltage into the coil mechanically.

Model T you say... I have to admit that is a little before my time. But you are dead on with the fact of the small spark gap on the switch. Know where I can get a set of model T points ? I guess you could say my switching device is modeled after a 70Ã,’s ford before electronic ignition.

This type of circuit should pulse the battery into the high voltage car coil.  You would have to 'play' around with the values of the resistor and cap. to vary the speed of the chatter of the relay. 

The relay should start with power on it, pulsing power to the car coil as well.  When contacts pull apart, it discontinues power to the car coil too.  (When the contacts are open on the relay, it disengages the relay coil power and then discontinues power to the car coil, except for the back emf).  This cycle repeats over and over.  The rate of charge on the cap determines the speed of the relay cycle rate.

 Great idea, lets compare what I am doing verses your circuit. I attached a pic of my logic. What I was trying to achieve is to be able to adjust the frequency of the pulses with the rotation of the cam. I then need to adjust the frequency of the on time verses the off time which is the width of the gogÃ,  or cam lobe. I have found that a millisecond switch on time with a longer off time to allow oscillation in the vintage coil works the best. With modification to your circuit, I think I may be able to achieve this and allow me to adjust easer the timing device. But IÃ,’m not to concerned right now with the input driver as I am seeing promising effects on the Tesla side of the circuit and want to concentrate on this side. I much appreciate yours and anyoneÃ,’s input. It would be nice to find someone in my area who would want to do some serious Tesla experiments with me. Its takes so long to try each little thing, document it and wrap some more coils.

You are welcome to use the circuit if it will help you.  I just pulled it out of thought, it  is only one of many variations of that type of circuit that one oculd use.  It may not be as fast as the rotary setup that you have.  But it is simple and easy to use.  Kind of a thow back to the time of Mr. Tesla.   

I hope you have much more good success with your circuit.
