ARSG II (Asynchronous Rotary Spark Gap)

Introduction

This is my first high powered Asynchronous Rotary Spark Gap (ARSG).  Although the previous propellar

style (ARSG I) spark gap worked quite well, I need to have something with a little more brawn for those

bigger coils.  At the Rochester 2003 Teslathon, I managed to pick up a brand new rotor and universal 

motor from an individual there for $240.00.  Figuring the motor alone is $140.00 new, it was the bargain

of the day for myself.  The rotor was complete with a hub and six pure tungsten 1/4" electrodes.  This rotor

was machined meticulously well by Ed Wingate and I was lucky to get such a piece of workmanship for

the price I did.  

Once home, I ordered the rest of the materials I needed from McMaster-Carr and built away.  The ARSG is 

now fully complete and has already been tested on my 3kW PT powered tesla coil.
