Hi Roger,
You're right about the staples. The problem is that they are made from a
different metal than your elements from Euclids. A chemical reaction takes
place when the two touch and it melts the elements. Where my staples
touched the elements, a greenish metal appeared. It looked like a raw
frothy copper carbonate.
If it's any consolation to you, I did the same thing in my gas-electric
combination kiln.
I had to order a new set of elements. When you do this, have them make
some staples for you out of the same metal they use for the elements. That
will fix the problem.
I tend to think of all things that go wrong in ceramics as "Edison
work". You know finding out what doesn't work.
Don't give up yet, you'll get it to work. One good thing about your post
is that it now confirms that I am not the only person who that happened to.
Cheers,
John Post

Had a very discouraging experience with my brand new AIM kiln, following to
a "t" Nils and mel's directions. After the treating, (itc) and rewiring, the
whole thing, I was happily doing my first ^ 10 reduction firing on some test
tiles and at 1700 F the electric plus propane flame started losing temp. I
realized that something hed gone wrong with the coils. Cooled and discovered
that the top coil had burnt out. Took it out in 11 pieces! Have absolutely
no idea what could cause something like that. Ordered new set of Euclids,
but confess I am a bit snake-bit on the subject. What would burn out a set
of brand new AIM coils? Only diff I can see in mine and mel's is that mine
is 1.4 cu ft little aim, not the very small one. Any ideas, let me know.
Chief suspect: the little staple shaped pins that AIM had to hold the coils
in the proper place. I may have opened the door to shorting out the coils by
reinstalling them incorrectly. Or, could my coils have been designed for a
120 rather than 240 that I have?
Obviously I know very little about electrical matters, so for gosh sakes
don't flame me for that!
What are the possibilities?
