Re: non sync rotary.....

The reason it's erratic is that the gap presentations are not 'in 
tune' with the line frequency.  I think someone on the list is 
selling some sync motors right now....maight wanna look into 
that.  You can sidestep the trouble if you did a full wave 
rectification of the output of your transformer and then used a nice 
smoothing cap...possibly adding some chokes in the circuit to give 
your gap a contant high voltage source.   I've heard of people 
grinding 'flats' into motors to make them synchronous,  but don't 
know how that's done.   Good luck with it.

Have ya ever had a coil that just wouldnt run right with a rotary,
but runs great with a static gap ?
               I built an eight point Async rotary for my Lil' 4"
coil,  ive messed with gap spacings , speed, and ballast
adjustments,...the result is erratic operation and low spark otput...

    years ago, I built a gap for my 8" coil,.....it worked great,
and, I could switch between static and rotary with no coil adjustment

  not sure whats going on,...hey, static gaps are cool, right ?  :-)
