Henry -
This sounds plausible, but do you have any actual data (scope waveforms,
etc) that would support the claim of better quenching from a "propeller
gap" vs a conventional static spark gap?
The data would have to be generated from a test setup where the only
variable was the substitution of the two different types of gaps.
If you have data, could you share it with the List?

Among other things, the propeller gap is better at quenching (shutting
off the spark), especially at high power.

motor
from a 8" hard drive now and am going to build a mount as soon as it is
warm
enough to get to my shed. My question is why is a propeller at 3600 RPM
better than a RQ copper tube gap? 60 cycle RQ vs a 3600RPM it's the
same
break rate I think.
