MY NEW 42"OVEN BUILD.

[JRPizza]

I used the high temp caulk as I had left over from sealing up my chimney flange and my rope around the heat break, but not sure how necessary it was. My crack is right in the back, and the first time I saw it the sun was shining through it while I had a fire going. Probably about the same size as yours was. I don't know if it was impatience, not having insulation, or just where it was going to crack the first time it got hot enough, but I am probably the only one that notices it.

You can pack some mortar in there or high heat caulk if you want to, but really it won't affect anything in the long run

Bad crack from last firing, my impatience got the oven too hot while clearing the dome. Please guys chime in if o should fix or leave it. The crack is about 1/16 to 1/8 wide and í can see the flame inside the oven.

The good news is í was able to clear my oven dome with the last firing, bad news is í have a large crack from the soldier brick half way up my dome side. Cooked my first pizza and it was awesome.

Thomas, do you need just the spark arrestor or the entire rain cap? I ordered my cap without the arrestor, but reading the description and looking at the picture I am going to make one using the left-over stucco mesh I have. The arrestor is over $10, but you can get around 16 ft^2 of lath for around $7 at the hardware store. If the Menards one was stainless I might buy it, but it is galvanized steel (like the mesh), so a little re-purposing is in order ;-) After typing all this I see there are stainless ones available, but Menards says galvanized.

You definitely need the rain cap. I haven't put a spark arrestor on there yet and will probably make my own as well.

I agree on the DIY spark arrestor. I paid something like $15 for the Duravent arrestor, only to find it's just a little roll of ½" stainless hardware cloth. I had bundles of that sitting around already.

Too bad that Menards is only local to MN/WI, but unfortunately they don't have the vent adapter and spark arrestor available in stores, but I could pick through everything else and find stuff that was nice.

I'd at least try to get a discount on it... Stuff is expensive! Mine got to me ok but the raincap was smashed flat.

JR, I think the dented pipe will be ok, wont see the dents after my enclosure is up but still not happy about it. The worst part was the flange that connects to the supervent was out of round so I had to shape it with a rubber hammer. Still waiting on my rain cap. All else is progressing nicely, slow and steady with the curing heat.
Thanks
Ivan.

Ivan, will the dents in your pipe still be visible when you build your enclosure? I ask because it took three shipments to get a pipe that only had small dents, and they were triple bubble wrapping them and the shippers still managed to dent them (or they were dented in the warehouse). The one I am going to use had small dents in the back, which won't be visible when I get my walls up. If you order a new one it may be worse than what you have now, and you will be like me - stuck with some dented pipe you don't know what to do with.

Started 3rd day of curing with pine kindling holding temps at 300°-350°. Might be giving Menards a call cause my 36" pipe was all banged up right out of the box. They also forgot my rain cap. Guys thanks for chiming. Ivan

Saluki is correct. Insulation doesn't have MUCH of anything to do with the high temp. What the insulation does is ALLOW you to get the higher temp faster since you are not heating up areas that are acting like a heat sink. In addition it will maintain the heat longer, at least in the dome area.

very nice Ivan!! is this the quickest build on the site? good job.
i just posted on my build's thread about getting the same supervent from menards. i dont live near, so i'll ship it. seems to be half the price of duravent.

[Saluki]

I don't think insulation has anything to do with high temp, I think it just helps maintain the heat itself, after firing the oven.
