Hey, I realize this is an older thread but I would very much appreciate some help with building a similar oven. I'm building a smaller oven using a (smaller) metal filing cabinet (great minds think alike) and the elements from a large toaster oven. Mine is intended to bake gun parts for thermal coatings like KG Gun Kote with a temperature range of 100-400F (300-350F mainly) and I know that my plan will hit 450F using 110Volt, which I like over having to use 220V for something like you've built with the electric stove elements.
My question is about the electronic temperature controller, the solid state Relay, and the thermocoupler you purchased from Ebay. I love the idea, and they are in my price range. I've found these on Ebay, but electronics is not in the sweet-spot of my skill set. Could you explain more about your temperature control set up? IN laymans terms, why is the SS Relay important? Most of these tempcontrols are offered with a type K thermocoupler, seems to be the proper range, correct?
Many of these TC give a range for the voltage, not specific 220volt or 120volt, do I need a specific temp controller designed for (standard american 3 prong) 120 volt power supply, or would one of these controlers (typically using 220V) work for me.
any guidance in how to wire this would be greatly appreciated. I hope you guys still see this thread. Please help, I'm happy to post pics of my build here if it helps others.
