RE: ASRSG Smaller Sparks????

I knew it wasn't in sync from the beginning.  I ran the motor with no
disk and it did that hunting thing.  I really think that I didn't shave
enough from the armature.  Instead of opening it back up, I just went
for an ASRSG since the rest of the thing was ready to go.  I have read
where a lot of people have had great success with ASRSG around 400+ BPS,
and was just disappointed with what I got.  I even put the motor on a
variac and slowed it down a bit to see if that would help-NG. I turned
up the variac to apply more voltage to see if it might sync one of the
two sets of electrodes, but the spark kept rotating between them.  I
just have a problem showing a 6" coil that only puts out 2' sparks.
Should I have changed cap size going from a static gap to an ASRSG?

Hi Randy,

Sounds like the srsg is hunting. It's "not" in sync so your firing at
various places along the AC line and probably very inconsistently. It's
probably your disc assy is just too much for the HP of the motor. Have
you
tried the disc without the electrodes to see if it locks in sync? I
would
probably suggest troubleshooting the srsg problem, otherwise I think you

will be better off with the sucker gap.

Take care,
Bart
