Insulators

I bought a big potted neon sign transformer on ebay, but both of the hv
insulators were destroyed in transit (this is me, having a positive
attitude...).

Anyway, I'm wondering where I might get some new ones to replace the broken
ones? Any ideas? They (were) about 5cm long, 4.5cm wide, round, with bolts
on the ends:


|-| |-| |-| -
==| |=| |=| | |
| | | | | |={} 4.5cm
==| |=| |=| | |
|-| |-| |-| -

------ 5cm ---|

They look like the kinds of things on power poles, only smaller.

There are pictures of what is left of them here if you don't like my ascii
art:

Take a ceramics class and make your own? ;-) (or go to the hobbies and
crafts store, and see if they can give you some pointers...)

Otherwise, surplus stores, search for "steatite insulators", etc.

Good Luck!

See if a local sign shop has a bad transformer, and will let you
'harvest' the insulators.

Epoxy a couple of plastic tubes where the insulators were. Extend the
HV leads out, as wires or bolts. Then fill the hollow tubes with epoxy
or silicone caulk.

SIlicone caulk is _conductive_ until it fully cures so BE PATIENT if
you take this route.

Thanks John and stratus46. I'll give this a try. I have some epoxy laying
around. Much easier than trying to re-pot the monster, which looks to be a
nightmare.

If you pull an arc between the ends, it makes a nice soft bzzzzzz
sound. Add an old TV set doorknob cap across the ends, and the arc
goes BZZZZZAAATTT!
