Is that a Haiku Marty?

I've seen enough element creep that I want to be able to pin it when I see it. Can't exactly do it in a tube. I lean towards the recessed elements more because pieces potentially falling over, less about personal safety. If that's the real goal, then a door switch is a much cheaper alternative.

I love this group sometimes. So much better than Glassies.

I built two annealers with 2" skamol inside backed by fiber. They worked great. I routed the element channels in with a normal router.

I also used a piece of left over skamol for the inner hot face ceiling in my pipe warmer. It held up fine in that context for years and is still in service and doing just fine.

Thanks Scott, I was hoping I might come across someone that actually used it in the way I had planned. I liked the idea of having a more ideal machining surface than fiberboard or brick.

I did have an IFB floor in both of those oven. I like a brick floor.

If I had it to do over again I don’t know that I would use an expensive controller, I think I paid 15-1600 bucks a piece for these and all I do is turn them on and off....I don’t run a program anymore, they cool so slow I don’t need to.
They hold the heat and are still around 250/350 in the morning after cooling through the night. I’ve done it this way with pumpkins and paperweights since 2014 without any problems

......would the cost of the extra fire brick to do the walls and ceiling be offset by eliminating the cost of an expensive controller and the electricity to run the annealer every night all night?

There's a difference between annealing and kiln action Lawrence. Your approach works in a coarse annealing sort of way but you would have issues if you were making thicker works. Controllers are relatively cheap actually.

😂 ...on average I would say my pumpkins weighed about 3 lbeez...paperweights are pretty thick too.

My point was mostly directed to the cost of ifb being a non issue.....🤔 does that make any cents

If the kiln was for blowing I'd consider it, but a flame cycle is so short ifb doesn't add any benefit. The other kiln is for powder coating, so that's even less of a concern. I want it to get hot fast and cool fast.

***

make a few witness weights Lawrence. Just straight clear and make them exactly the way you would do your regular production. Then Check them in a polarimeter. If it's mostly grey, you're fine. If it has a presentation of color(s) or big "X" s you're stressed.
