I'll be in tomorrow in the day to do some work on this... it needs some electrical/safety tlc. I'd be in tonight but for work cocktails!

Just a thought... laser cut foam gears, cast in bronze via lost foam casting... yum
Feel free to buy me a beer :)

For once, google's ads put something really quite interesting up against this thread :

Not as good as a real-life kiln I'm sure (an aquisition I enthusiastically support) , but sounds worth investigating.

A friend of mine uses one of those for tiny jewellery pieces. She
seems to be having a lot of fun with it but accepts that it is pretty
limited. I think we can do better with this thing :-)

well we have the kiln but the electrics for it (according to Niels) don't work so we'll have to do some fixing.

We gave the trader 15 minutes to get the thing working, while we ate
some noodles, but he couldn't.

He claimed that it was working this morning and that he was selling it
at a loss with the discount for non-functionality.... LOL

What's wrong with corroded, exposed mains wiring? I did like the way
the trader demonstrated it's safety by touching various bits of bare
metal while it was plugged in. Now *thats* selling something you
believe in.....

I did a fair amount of research into these a while back. Alright for
PMC and some enameling, but a real kiln is way better.

Sounds like he was very confident that it didn't work :)

Kilns fixed! I opened it up and checked the electrics - its got a thermionic valve in it! Turned out the problem was actually a mechanical one with the temperature control...

Anyway, we did a test firing of it... temp was maxing out at about 500 until i did another hack.

Result: we now have all the little iron bits from harddrive spindles and a puddle of of aluminium. Rar!

Going home now, will be in tomorrow to play with it some more. Sorry for leaving kiln on bench, its a bit hot so cant move it right now. Be careful if you need to move it - its heavy and will need two people.

Huzzah!

Could you update the new equipment page for the Kiln to reflect what
you have learnt and any other important information that people should
know?

Yuck!

I think that side of things needs a bit of modernising, and sooner rather than later. To that end, I have
bid on a temperature controller: http://cgi.ebay.co.uk/220745096118

It will need an SSR to go with it, but they are fairly cheap. And a housing of some sort, I would expect
the existing control location to get rather too hot for it.

Excellent!

Has anyone volunteered to order crucibles yet?

There have been some concerns raise that the insulation for the kiln may contain asbestos. 

The type of kiln (as far as we know) is a Gallenkamp 'muffle kiln' (or furnace).

My (albeit limited) understanding was that there's not really problem
with stuff that contains asbestos. It's perfectly safe as long as it
stays in situ and you don't drill/saw/etc it.

Nooooo, 

Leave that temperature control alone ! Keep the electronics in your iPod !

And especially leave that beautiful bakelite meter with the thermocouple alone  - it just needs a new glass !
