I built a similar oven and have been using it for months. You do develop cracks that may in the long term ruin your oven. Mine started as hairline cracks releasing moisture and have developed into ones that actually release a little smoke. I expected it and am not disappointed as the oven works great and the cracks do not diminish the performance. I have probably run it 10 times with food and the cracks do gradually get larger. Enjoy it!
Pizza!! Finally got some actual pizza in the oven over the weekend. The oven performed great, I on the other hand had some issues. Had three pizzas on done up, ready to slide into the oven, but only one of them "slid" ito the oven. I even know better. Anyway, had more dough and toppings so I whipped up a couple more and ate!
The oven did great. I only have a couple pics but if I wasn't there to screw it up, we would've eaten much earlier.
Live and learn.
This is such a cool thread and I'd love to build one, but ^^that^^ makes me worried. If the cracks keep getting bigger its only a matter of time before they become a structural issue.
Really...! I mean Really!!!! I'm in the middle of buying a smoker after deciding I want more than my weber kettle and now THIS! You guys are gonna ruin my savings account. This looks awesome and I got a perfect spot in the back yard....gotta build. I live 40 mins away, when is pizza????
