Gunsmithing Wiring an Oven using Electric Range Control

[woodsy]

Am in the early process of building a larger paint curing oven using an old gun cabinet and came across the guts from an old electric range. I have the controller, 2 round burner elements, temp probe, power bar, and what appears to be a limit switch (looks like a button that sits inside the oven itself).

For the life of me I cannot figure out how to wire this thing. It's a bit embarassing since I've wired 4 complete shops from start to finish and countless other large projects dealing with 110 and 220 volt. This project, however, is kicking my butt.

Anyone have any ideas how they might wire this controller to burn 2 elements? I have no idea what is supposed to go where and there is no wiring diagram for the old stove. This is a 220 v system but damned if I know where the 2 lines would feed from the wiring bar into the control . . . or where power goes from there. Help?

Woodsy,
Since you stated that you are building a larger paint curing oven, I suggest you use equipment that is more pertaining and specific to the quality of your work. Using a PID Controller from Auber Instruments. Their website is auberins.com, Temperature control solutions for home and industry and I am not affiliated with them in any way. I have only been a customer of theirs, and the items that they offer are very reasonable, and work exceptionally well.

Here is a link for a controller that I use, and would work wonderfully for yours as well. I say this, as I too have two elements in our oven here, and it runs flawlessly.
Universal 1/32 DIN PID Temperature Controller Universal 1/32 DIN PID Temperature Controller [SYL-1512A] - $36.95 : auberins.com, Temperature control solutions for home and industry
It appears that they are out of stock at the moment, but should have more in next week. They are very knowledgeable and helpful on the phone, too.

There are other threads here already, showing how ours is installed and in action. Go forth and prosper!

(I say all this, as I have been told that typical 'oven' controllers have quite a "range" (pun intended) of degrees and are nowhere near as precise as these inexpensive units.)

[[bear with my links as well, as I am still learning how the new 'hotlinking' system thingy works.]]

Agree with above. I switched to one of the PID designs a while back, got it from Ebay. With a few seals replaced on the oven, I can keep the temp within .5 degrees all day. Coupled with a good Solid State Relay and you should be set. I need to update my original oven thread on here to show the changes. It really did make a huge a difference in the oven's performance and my confidence in what temp the parts were cooking at. Plus it looks cooler than an old knob sitting on top.

Might have to incorporate one of these into my oven project.

Here is a oven I built. The PID's work great..

myownman,
What type of elements are you using?

I bought a walmart Black and decker toaster oven for the elements...
