Huh? The JB Weld FAQ claims it's not conductive (even though it
contains iron filings).

Q: Will J-B Weld conduct electricity?
A: No. J-B Weld is not considered to be a conductor. It
is an insulator.

Perhaps they think it's not. I glued a thermal fuse back to
the case of the crystal oven in a Cushman CE-3 after repairing
the oven control. Quite impressive when I plugged it back in.
(The fuse is connected to 120 vac)

I think their answer is in regard to people that want to use it
as a liquid solder.

The problem is that the JB Weld goo is mostly epoxy, not metal. There
are wide insulating spaces between the metal filings. In order to be
conductive, the metal filings would need to overlap, as happens with
the flat sheet flakes of graphite in Aquadag (crt shielding) and
aeromatic solvent based silver shielding coating.

My guess(tm) is that one lead of the CE-3 thermal fuse was connected
to the metal case, or that one lead of the thermal fuse touched
ground. I won't bore with my opinion of the CE-3 and Cushman.

I don't have any JB Weld handy, but I'll drop by the hardware store,
buy some, make a few measurements, and send you the bill.
