I purchased the controller, solid state relay and thermocouple on evilbay. I had a junction box, cord, wire and outlet laying around that I used to complete it. The box I used was deep enough I could have mounted the controller in the door (Would have been far easier to wire it if I had) but I wanted to lay it on the back so I could set my Lee pot on top to raise it off the bench a few inches. I also made a cover for the box with some scrap lumber and a piece of plywood to raise it another couple inches. All told it sits a bit over 7" off the bench. I watched a Youtube video where the guy took the control box apart on his Lee pot and bypassed the thermostat. Why do that?? Just turn the knob all the way to 10 and let the controller do it's job. If I ever want to use the pot without the controller no rewiring needed.
The Good...
Works great. Keeps the temperature within 3*.
The bad...
The REX c100 read out is in centigrade. I guess that is not too bad, but it would have been easier for me if it had been in Fahrenheit.
