Greetings Rob, Barry,

No need to build a variable speed rotary, because as a properly equipped
Tesla coil and rotary gap builder, I already have several on hand that
fill the bill. I will be trying more experiments with a variable speed
gap on the twin coil system as soon as time permits.

I am currently very busy building the base and primary for my new
magnifier driver #2. Driver #2 is 5" smaller in diameter (32") than my
first driver, consequently I could not get the high coupling factor (.5
to .55) I wanted for the new driver using the old primary. Rather than
rebuild the old primary I decided to go with a newer, slightly different
design.

Safe Coiling,

Ed Wingate
