Robert asked about the drill size for the ends of the fuses.
For the late tests, I just tacked the PicoFuses on the outside
of the fuse bodies.  Years ago when I first messed with it,
I drilled the ends out, tacked a pigtail on the Picofuse
and inserted it down the barrel, re-soldering the ends.

Well I finally found the one's I've drilled.
Some of the fuses have powder in them 
which I just tapped out,  but I neglected to mention
(or forgot over the years more likely) others
have a star-shaped ceramic insert in the fuse barrel
with a hole in the center to keep the fuse wire
off the surface of the barrel.  You have to 
tack the pigtail on neatly so it will fit through
the hole.  Here's a photo.

Oh ... Robert:  The drill size is 5/32, 
but anything close works.  

Or you could just tack them on the outside, 
but I don't recommend it.  
Forget yourself one second around 
that exposed 1000V wire and ZZZZZZZZAP!
