Gym Ball Pizza Oven for less than $250 - Part 1

This is the first part of putting together a pizza oven. I built this dome using Perlite, Cement, a gym ball, couple bucket cutouts, and a 4' x 4' x 1/2" plank. All for less than $60.
Perlite used:
www.amazon.com/Viagrow-4-cu-F...
Got questions around perlite and cement amounts used, so the whole bag of Perlite was 4 cubic foot, and I used a bit more than half. Cement was the regular 94lbs portland, and I used about half that bag.
Question about the ball size and the plank used: Even though it's a 52 inch ball, it was not fully inflated and the plank was sold as 8x4 and cut in half to get 4x4. It probably was an inch or two larger too as the lumber places often cut them a bit larger than exact measures.
Another question: Where I got the ball from?: It was from Walmart. I don't see it available anymore and see the prices of the gym balls in larger sizes got very high around March-May 2020 due to people start working out at home and demand for those gym balls increasing.

@AnjelicaDumanovsky 4 жыл бұрын

2 questions. First one is silly but I’m using a slightly smaller ball, what is the best way to measure the circle size you will need to cut out the ball hole on the plywood initially? Secondly, if you use a perlite and cement mixture, will this be okay for withstanding heat? Just got a bunch of my initial materials in and excited to start.

@fixiteasy9080 4 жыл бұрын

Well, the size of the ball is actually your radius for the circle you'd cut on the plank, but I suggest cutting a bit smaller radius circle than the ball radius so the sides of the ball fits in the hole with more pressure. That helps with its stability while rendering the perlite mix. If you don't know the size of the ball, just blow it up and have it touch on the wall and with a stick, do a 90 degree angle to the floor on the exact opposite end and measure the distance between where stick touches the ground and the wall. I did use a perlite mix and it's been withstanding more than 1000F. After 2 years, no issues with the heat. Hope my answers help, and good luck with your built.

Hi, Thanks Malin. It doesn't get hot at all. I think I have a section in one of the videos showing that with a thermometer. The fire blanket really works well to keep the heat inside.

Hi, I'm glad to hear your build was successful. I was worried about the same thing and thought about doing the same , but ended up going with perlite mix only and got used to it and now don't really worry about it at all... The mix in the inner dome does a great job keeping the heat inside and keep the rest or outer shell cool. I am not sure if a layer of cement inside would stay fine with 1000+F temperatures.

I am not sure, but probably you can drill a hole with a sharp bit and a gingerly approach I guess. But, for temperature, I usually use a laser/infrared temp gun most of the time. I also use a cheap stainless steel in oven temp gauge now and then. you could also attach the temp gauge on the door if you're building one.

Great job! You mention 52" ball as the size. Is this correct? Reason for asking - the base is 4ft x 4ft which is 48" x 48" - smaller than the 52" ball, but the ball fits into the base. Was it the degree of inflation? I'm thinking of using a 60" ball I have found.

@fixiteasy9080 4 жыл бұрын

Thanks! I think someone else also had asked the same question. So, the ball is not fully inflated at all, and it kinda is squeezed right in the middle for stabilizing. If you're using a larger ball, I suggest building it on a very sturdy base and don't plan on moving it anywhere. With this 52" ball, the weight is substantial, so a larger ball size would be even heavier. Good luck with your build, and please make a video, so we all can see it.

Congrats... Insulation is on the outside right? so, you can put it on top, but I'd also check for the weight a bit. I don't think it would cause any issues like collapsing since the insulation is probably not heavy, but also you'll likely be carrying the dome to a platform that'll be its final place, added weight might cause issues carrying it. Just a caution. Good luck and let us know how it turned out for you.

I did think about getting an oven like yours and decided to build myself because of a few reasons: first, the ones that were not crazy expensive were not large enough. For example, yours is 25" x 30" = 5sqrft cooking surface. Mine is 14.5 sqrft, almost 3 times larger. Also, I wanted to try some bread making too, which needs to keep the temperature on a level for a while without adding more logs into the oven. I couldn't see a stainless steel oven doing that; might be wrong though. And of course, it would be me building it, so it was a lot of fun while everything is fully customized to me, unlike most store bought ones :) Anyways, having a pizza oven definitely beats not having one, so enjoy yours, and make lots of pizzas...
