pics of my pizza oven mold
 
3 Attachment(s)
hi all, I have been working on an outdoor kitchen and sharing photos on another forum I belong to. I lurk on here regularly and decided its probably time to join and share some / get some information. In my previous career I was a tool/model maker for the aircraft industry which gave me the background for this project. I am attaching a few photos of my kitchen and pizza oven mold, which I obtained all my info and dimensions from this site. I have obtained all the castable and insulating refractory from a local source here in Ohio. feedback appreciated. hope to start casting this weekend, will be in four pieces like the ones for sale here.

How did you build the mold? I would love to do the same thing.

I made section templates with wire between them then used plaster to fill in

you taking orders? :)

But seriously - is the mold reusable, or a one time use affair?

The problem of having four sections as you have them, is that the top of each quarter gets hot really quickly while the bottom of each section is still relatively cool. This leads to uneven expansion and fracturing. It shouldn't matter too much though as the structure won't fall to bits. Did you add stainless steel needles to the castable mix?

I should of went into more detail, if you look at the pictures it is actually five pieces, four quarters and a round plug on top so there are no points to crack. have had many fires at this time and there are no fractures anywhere to be found, yet?? no needles.I worked with a furnace designer to come up with the proper commercial grade refractory and casting process for this. this is not a home brew

I did not build the mold with the intention of re using it so it was broken in the process. seeing the way it worked I kind off wish I would of made it reusable. but then again how many ovens are you going to build??? this mold weighed in the range of 300 lbs and was 5 feet in diameter with the entry.
really did not want to give up the space to store it. I could build another one in a week for acouple hundred bucks if need be.
