I didn't track the cost too well, I think I am under $1,400 on the entire cost just from adding it up in my head. The most exppensive part was the castable $ 350
the tires $ 60
the axle $ 170
perlcrete $ 250
Leg &- $ 50
-hitch
Frame- $ 125
-steel
paint $ 10
Total $1,015
(unless I forgot something that should be about right)

The weight is around 1,200 lbs. (I need to upgrade the tires to bigger ones that can handle the weight these are rated to 900lbs so add another $200 bucks to the final cost)

wow what a cool project. I have a question how thick did you do the oven walls ? also have you noticed any cracks.

Also is the refractory cement safe to cook on. For example naan bread is cooked on the wall of a tandoor would it be safe to do the same in the refractory ovens. I know I have the floor I can do it on but just curious.

I have been procastinating building an oven myself as the cutting of bricks scares me but I am willing to to the cast cement if that is going to be stronger and safer then the bricks.

The cast walls were about 3" thick. The refractory concrete I used is very hard and I think it would be fine as a floor but it may crack. My dome developed three cracks total, about 8" long but it does not affect the performance of the oven.
Good luck with your build and post pictures.

With a diamond wet saw, firebrick cuts like butter. An unsegmented diamond blade is FAR safer than the common wood cutting blade. No need to fear in this case.

The idea of scraping a metal peel over chalky refractory concrete is not an appetizing concept to me.

I don't understand the sand. Is this just in place as a mold and then once you have cast your dome the sand comes out?
I'm looking at using an old 42" diameter propane tank standing on end but would pour the dome and walls before turning over.

Yes the sand is used as a mold (mould?) and it is just dumped out after the concrete dries.

Hi Joey
Quite an engineering feat and a real beauty as a finished rolling WFO!
I like the bottom line on your spreadsheet too. I, too am considering a cast build. I am still investigating design and materials.

I noticed your great price on the castable refractory cement. When I try the links you had for WESCO I get dead links. Do you know if they are still in business?

I can try to call one of the phone numbers that I can still find on the web, just kinda wondering if you knew anything more recent about them.

Thanks for the timeline and pics on your sweet rolling oven.

John in Merrill
