Take care,

Bart,
You're using a static gap not a synch rotary gap right? The static gap
probably can't draw as much power through the NST as a synch rotary can.
I can't remember what kind of gap I was using when my re-potted 15/60 NST
drew 25 amps. I also don't remember how much power Gary's 15/60 drew
back when he was using the static gap, but I know the sparks were a lot
shorter than they are now.
