Hubbard coil

i beleave bifillar can be used a few ways....

Thanks, but, my question was how do we know that bifilar coils were used, not what they do.

perhaps they wernt used in the faction we normally woud use  them maybe they are used in a transformer faction  ie primary and tuned

secondary and what if the secondary is really your resistor and your choke coil when we think tesla this sure seams to be the case with his

steel ball or spear a top some of his coils...  ever see the 6 spear tesla coil??

I went back and read every post. I haven't built anything along these lines, but I'd like to inject this into the forum, as the topic has been covered only a little. The excitation method Hubbard used was a HV source sent through an automobile distributor that had possibly a variac that controlled motor speed that spun the distibutor shaft.

If I have a distributor with 8 plugs wires, I could send a pulse train out the top of the distributor instead of the other way around. I could tie the plug wires common to the HV source and have 8 high voltage DC fast transit events per revolution of the shaft. A thousand RPM on the distributor would then mean 8 thousand events.

It appears that he was (guessing some more here) watching for a bulb to light (or a space heater to glow) to indicate he was "in the area" as he adjusted the variac. I'm going to guess also that he didn't vary the HV impulse strength, just the timing.

Each set up he built probably had it's own timing. I imagine that the most important part of the thing is that he probably made sure that his wire lengths on his coils were matched.

Could anyone point to the actual information from the time period that verifies this claim.? I have collected a lot of info on the Hubbard generator, but have not seen this info.

Thanks in advance
