Hmm, I'll probably do that then, although the distance between the 2 terminals is about the same as the distance on the flyback's container and nothing seems to have gone wrong there, even tough it's been powered up multiple times.
I suppose nothing can go wrong by putting plastic there though, now to find a shard of plastic...

I had surface tracking occur on a flyback before from pin to pin... that flyback is no more. Theres not much you can do about it once it starts, so make sure it doesn't.

If you catch it quick enough and cut the power, you can usually scrape off the carbon and apply some silicone to keep it from arcing.

My bad, meant to say once it's established. on a similar note... superglue is conductive... and it burns bright yellow.
[EDIT] @ grenadier, where does the backlight (I'm assuming LED's) get it's power?

Alright then here is what I have.
A working multiplexed nixie display, a new box with a CNC'd cover, and most of the circuitry, aside from the battery section done.
Now I have come to a crossroad, should I glue a second box to it like I did before, or should I keep the actual x-ray head seperate and connect it via a cable? I could fasion a cable using octal base tube sockets and some hose. Keeping the head seperate means that positioning it will be easier, however that also means that some potentially high voltage wires will need to go back to the meters.
If the meters are working OK the wires will be at low voltages, <10V, however if a meter goes open circuit then those wires are no longer pulled down to ground and will get quite hot. Example, the mA meter is in series with the tube and ground. If it goes open circuit then one side is +HV and the other is ground. Maybe some MOVs could protect things...
