  • Book on building heat teat ovens

    There are a couple of instruction booklets on gas fired ovens such as this one,

    But does anyone know of a source for building electric ovens? I have searched here and come up with a bunch of info but still a heck of a lot of questions. I have a very large pottery kiln that I picked up for almost nothing, pretty much complete but missing the controller. My plan is to salvage as much as possible from this thing and build a small oven, approximately 10"x10"x20", but I would like to be able to learn as much as I can before before I start.

    In that thread I started a couple of years ago I said I would just buy one and that's how I ended up with what I have, I checked Craigslist before buying a new one and when I found the one I have now I thought I could have it operating for very little cost. Well I can but the darn thing is just too big so I never got around to doing anything with it until now. I just did a very quick scan of the links you provided and one in particular looks to be exactly what I am looking for, actually most of the info was here on this site but in bits and pieces that still left a few questions. Thanks for taking the time to post those links, I did a search here but I guess I should have Googled the question first.

      Hello radkins, built a toolmakers furnace based on a burnout oven described in Handbook of Lost Wax or Investment Casting which worked out pretty well:

      Bought Kanthal (or super kanthal) wire & wound the element, etc. Just used a meter on a thermocouple for temperature indicator. Going to update with a PID for temp control (someday). Regards, Earl

        There used to be a paperback called something like L'il Bertha by one of the Gingery family. It described in detail how to make an electric heat treating oven. Moreover, the book was cheap. - MM

          How about just reducing the volumn of the large one with fire bricks or other refractory materials?

            Well I have been chasing the links you guys posted and I have found some very interesting material, basically I have found what I was looking for so it appears a new project is soon to be in the works.

              Also check out Dudley's Paper on Heating Elements, can be found by Google. Has good information about the heating element design, so apply that with te Kanthal information and you got yourself a head start
              Amount of experience is in direct proportion to the value of broken equipment.

                  Thank you, there's a wealth of information there! How to select the proper elements was my main concern and that explains everything quite clearly.

                  CountZero, yes that too is very useful and I have printed out both pages you guys suggested as reference material.

                  Books??? Who needs books, we got the INTERNET!!!!!
