Hey man, that's a really great budget kiln build! One thing I noticed is that you are using copper wire for your thermocouple leads, that's probably a big part of your temperature error. K type thermocouples require "K-Type Thermocouple Extension Wire" be used between the thermocouple and controller to read accurately, otherwise you will actually be reading some "average" temperature of the thermocouple tip and each junction where the wire type changes.
Hey Dirty, good-looking little kiln you've got there. I'm looking to build a small table-top model, and this will steer me in the right direction. I appreciate your sharing and knowledge. I have a paragon bluebird for my workhorse, but it is restricted to 5" of height. So I may explore making mine in the 10" to 12" height range for small recyclers and the like. But you've given me the confidence to proceed. In one word, "awesomeness." Peace out!
The size of the kiln is only dictated by your power source. Most residential outlets are around 15 amps but if you did need a larger kiln than he made you could use a 220 volt outlet but I think it would require a different setup but the size kiln he made is bigger than anything I make
The inside dimensions of this kiln are 11"x 11" for the floor and 12 tall at the tallest point. This is perfect for most of my work. Depending what you're making you may want something different. There is a formula for watts of the coil vs the surface area in the kiln but I didn't really use it because I knew the coil would be fine for my size and I wanted it to work on a regular outlet which only has so many watts. You could use the same coil in a larger kiln, it would just take a little longer to heat up and the coils would work a little more to maintain temperature.
@@DirtyBGlass thank you. I’m thinking about making one out of a tool box and the inside dimensions would be 8”x8”x16” which is close to the volume of the one you made and if I stretch the coil out to 68” I can get 4 rows of coils in the back of the kiln.
@@metaldetectingpa1 that would work no problem. I built this kiln inspired by the chili pepper which is built from a tool box. I had one for a bit it was pretty nice but the door was only 4in tall .
@@DirtyBGlass I’m going to use the top of the tool box as my door. I’m going to cut to down to have a gap in the bottom for rods and tubes to be able to stick out and about 4 inches of the bottom is going to be a split door like you did with yours. I’m also going to set it up to be able to set up either horizontal or vertical so I can anneal something up to 15 inches tall

Thanks man, much appreciated 🙏. I'll try switching the leads .
Can this controller ramp down over a set period of time for the cool down? Awesome job on the kiln! 👏

Thanks for watching man, yeah I was a little intimidated at first but all in all it was a pretty straightforward project. Good luck👊
Thanks for sharing, is there a formula to figure out what size kiln I can build and be able to reach the desired temperature?

Well done

What are your inside dimensions of your chamber or how many cubic inches would this be good for to use as a glass annealing kiln?

@@metaldetectingpa1 that's a good idea, I'd love to see how it turns out, send me some pictures when you do it!!
