Hi all:
I have been silent here just being a spectator as I have no way to go this big. Apt living has its down side. I did come up with a small fix to one of your problems tho. Since you are not going at a high rate of pulses, I think this will help out thoes that want to see the spike directly and not kill the trannies.
I have done this many times and it works very well. Since you are using 24 to 36 volts anyhow, go find a good grade relay that triggers on 24v and just let the transistors fire that from say a pair of slabs. Hook the relay in place across the coils and run the circuit. It will arc violently if you do not use a snubber cap on the switch pins but you can directly view the output pulse and not kill things. It will take a lot of punishment before you destroy it.
For what its worth, you guys have a big audience out here watching how you progress. And progress you are. I am stuck at about 24" diam for ever.
