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! Rich

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!
