I took a look at it, thats one of the designs I have tried. Though I have
not tried a 10K resistor mine was a 200K.

The coil was run and tuned and working with AC. I wouldn't have thought DC
would change that much. Sure has proved me wrong in many respects now. I did
check the archives out a few weeks ago for DC information, Though I am still
at a loss ( bad pun there ? )

I tried 200K resistor, with and without spark gap, spark gap on its own and
yesterday a NST secondary. All of which didn't really do anything.

It is variable speed. higher the speed the better so far. Though I dare not
run my gap to fast as it might fly apart. The output went from sparks to 1
flame like arc at high BPS. pushing it more made it arc a bit further though
it started to pulse on and off.
