How did you persuade Jason Manford to do the voice over :-). Great video Paul, thanks for sharing. I broke apart my first attempt with the gym ball because I thought the wall thickness was too uneven and thin towards the top go the dome - and I was right. The flex in the gym ball tended to slide material towards the base of the structure. I solved this by using a Tyrolean Gun to apply the first 2 cm coat all over. I then placed a chicken wire frame over the cement mix and then finished with 4cm of cement, again applied with a Tyrolean Gun. Worked a dream and only took 20 minutes to apply. I used 5 vermiculite to one cement mix and made the mix fairly wet (worked better in the gun).

Hi Paul, Quick question, I'm currently building a similar style pizza oven. i was wondering if you've experienced any problems using just a sand base and brick on top? as this is what i plan on doing sand and firebrick. no cement mix.

@PaulLloyd 5 жыл бұрын

I used just normal solid house bricks and brushed sand between them. The first few pizzas did have sand in the base of the pizza when cooked! But after brushing them off quite a bit it was all good! I have had no problems with the base & it holds the heat well! I get a good colour on the pizza base & it cooks through 👌 Let me know how you get on with yours!! 👍

Hi. My Pizza Oven also cracked in the same way that yours did. I have smashed it all to bits thinking that I could probably re-use the materials. My mix was 5 parts vermiculite and 1 cement. I bought some refractory cement. I would like your opinion on how I should go about the 2nd attempt. I was thinking of perhaps using 4 parts crushed mix ( from the failed build ) with 2 parts refractory cement. Can you clarify what your final ( successful mix was please, ratios and materials ). Finally, did your render survive the heat. Other video's show various mixes for the 2nd layer, including just a layer of refractory cement or a 2nd layer of vermiculite / refractory cement. Your render would be the cheaper option but just want reassuring that it didn't go pear shaped after use. Sorry about the long winded question but want to get it right before making the 2nd attempt. Cheers Paul.

@PaulLloyd 4 жыл бұрын

Use plenty of cement. I found the refractory cement to be too dry & would do a 1 - 1 mix between that and normal cement. Also, the vermiculite didn't take too much water the second time round due to it being coated in cement. The top layer was just a sand/cement render and has held up pretty well! If you're on Twitter, I can share some pictures on there with how it is holding up 2 years later! @PaulLloyd10 Good luck! 👍

Hello. Cool idea to use the gym ball. Creative. Suggestions 1. I think if you soak the verniculite for 1 hour will have a better drying process. 2. If you add a Concrete bonding adhesive (Sikalatex) will increase the bonding of materials and strength. 3. If you add a final layer of foam cement will increase the temperature inside the oven. 4. For the bottom you need a ceramic heat plate as a base. 5. if you add a chimmeny for the smoke and air flow, you can add a metal plate to cover the exhaust. 6. You can add a door to keep the heat inside.

@PaulLloyd 5 жыл бұрын

I like the suggestions! I basically made this up as I went along and made a video from it! I would definitely do some of the things that you mentioned if I would do it again!
