Hello everyone. I have been lurking and reading for awhile now, but have officially started my oven build. Oven will be 4X4X6 lay down, but will have two doors on the side with an insertable divider allowing you to use half at a time if you wish. I have purchased 5 -2600 watt elements for a total of 13000 watts. Also have purchased all Auber products for PID and K type thermo with two 40 amp SSR’s. Structure is made out of square rectangular tubing, and insulation will be kiln quality calcium silicate.

Only real question at this point is if it is ok to line my interior with aluminum. The calcium silicate will be ridgid—almost mortar like(stacked bricks with sealant in between), so there will be no transfer to the outside of the oven. I am planning on using sheets of.010 aluminum merely for a dust barrier from the calcium silicate. Should I try to attach the aluminum in a million places, or try to not attach it except on the outer edges(for expansion) . I realize aluminum is more expensive, but i currently have in storage 6 sheets of 4 by 12 .010 aircraft aluminum, so no money will be put in to that part.

Am anxious to hear everyone’s input, and hope to get a lot out of this forum as well as hope to help others. Thanks Guys!!!
