Good question! The true breakrate will be governed by how quickly your
tank cap can be recharged from your power source. This can be
accomplished in two ways: increasing recharge current, or reducing gap
breakdown voltage. If you boost the recharge current (by adding more
parallel NST's or by reducing the ballasting inductance on a PT or
pig-driven system), your tank capacitor can recharge more quickly, and
you'll reach sufficient voltage to fire the static gap more quickly.
Under these conditions, a static gap system, when adjusted to fire at a
point significantly lower than the incoming mains peak voltage, will
automatically increase its breakrate. In a rotary gap system, increasing
recharge current will permit you to increase rotational speed and still
be able to fire at every electrode presentation.

BTW, it's quite easy to improperly set up a rotary gap system such that
the mechanical break rate (the rate at which you have successive
electrode presentations) exceeds the rate at which the tank cap can be
recharged. In this case the gap will fail to fire on a given
presentation, and will most likely fire on the next presentation. This
mode of operation can cause excessive voltage buildup by the time the
NEXT electrode presentation occurs, and can result in premature death of

Safe coilin' to you!
