The transformers are all 15000v. There are two 60ma and 3 30ma transformers.
I made sure that they are all in phase. I made sure that they are definitely
in phase.
That's the same type I am planning to build. How did you gauge the
spacing between the pipes? Is your gap snapping and sparking well or
does it buzz?

The # is a little block of wood to support the back of the little wood

I used the old automotive feeler gauge to set the gaps. The gap is a
"snappy buzz". (How's that for a non-answer?) It doesn't hum with the
60Hz buzz, but, because of the closeness of the pipe pieces, the sparks
are not loud snaps.

Perhaps the primary needs reworking. One thing too is that once the insulation
on the wires is burned through, it will always spark.
