Kiln

<< < (3/6) > >>

JoJoDapyro:
So, after lunch my co worker said he went home and pulled it out. I has a high low, and an on off. I looked it up online (Dixon A22H) and it looks like low is 1250 degrees, and high is 2000. First off, this being an older unit would it be possible to find a controller? and secondly, isn't it possible (technically) to hook the kiln up through a timer to turn it on and off to hold a certain temp for long periods of time? Let me know what you all think, I am a novice when it comes to kilns, but I am not afraid of playing a bit.

It is also about 36 inches square, and 18X18 on the inside.

Trapper Rob:
A friend of mine bought a computer program to run his he just bought a old computer to run it.

JacksonCash:
It is possible- you can make a controller pretty easily to do that sort of thing. A friend and I made one with a crockpot to make a sous vide cooker.

Dalton Knapper:
I'll attempt to show what I have learned. I too have the same type kiln, and the directions on this link seem to be a bit more than I can chew:

There are many discussions on this. I think there is a solution with a thermocoupler and a controller where it basically turns it on and off as needed like you say. Personally, I'm not sure why a 220V infinate dial type control just can't be wired in. There has also been a lot of discussion of this subject at  http://paleoplanet69529.yuku.com/directory in the flintknapping forum. It is searchable, but it may take you a while to read who did what to a kiln.

Good luck and if you hit on a simple solution, I'd like to know because I have a kiln that isn't doing me a lot of good. I have successfully treated Novaculite in it by running it X time and turning it off. Theoretically, if you are willing to babysit a kiln, you could use a thermometer thorugh the monitor hole and turn it on and off as needed.

JoJoDapyro:
I went and took a peek today. It is an old unit. It has 2 110v plugs, so I figure one for each heating element. Seeing how I wont be using both heating coils at the same time it think it should be easy to make one. Tyke was thinking a Furnace controller and a high temp thermocouple would do the trick. He is the HVAC guy, and pretty dang smart when it comes to thinking out of the box. I'll post some photos of it in a bit.
