I've made a rolled cap this weekend and was tuning my TC with the new cap,
but have only a long enough wire to reach about 40% of the winding. How
sharp is the tuning? 1/2 turn? 1/10 turn? I'm using a a series gap, not

I just got my copy of Corum & Corum _Vacuum Tube Tesla Coils_ and one of the
first things that the "Engineer Corum" says is (paraphrase) YOU CAN'T TREAT
THESE AS LUMPED CIRCUITS. I'm finding that out myself:)

You're right I keep thinking of a standard xformer, not a shunt limited one.

Yep, the standard engineering model don't work here.

Of course! I should have engaged my brain, before putting my mouth in gear:)
I hate to say it, but, I've cought the bug! I started out to build a small
power oscillator driving a Tesla Resonator at a few hundred watts, but in
shopping surplus, I found a 450-900 VA xeon arc lamp ignitor transformer
(shunt limited like a neon) and used it as a quick get started source. Now
my wife wonders why I walk arround the house mumbling MORE POWER.
