36" Corner Build in Minnesota

[MnDude45]

Thanks for the feedback. I got another course down today. I can see how easy it is to get stung by the droop. I need to keep on eye on it.

If you get the droop it is not the end of the world. It can be fixed as you go. Just is a bit of a pain to deal with. I had it on my oven and some place there are pictures of me putting a bunch of slivers in over the door to get back to round.

Just in case you haven't read similar posts, I think that this is a good thread that will help keep builders from getting it. What is the "Dreaded Droop".

[MnDude45]

Gulf - I see it in the corners where the dome meets the arch. Great reminder and I’ll try to compensate in the next row.

Looks great. If it hasn't been mentioned earlier in the thread, now is the time to take actions to avoid the "dreaded droop".

All rightly, you figured it out. This is one of most difficult concepts for builders to visualize.

You're on your way....lookin' good.

Today was a good day. I completed the inner arch and it appears to be lined up right. If not, it is what it is now.

[MnDude45]

Yes, I have been adjusting for slight differences in distance and angle for each course. Thanks for the reminder.

[UtahBeehiver]

Remember that since you IT is offset at the base it does affect the true ID and OD of the oven at each course so you need to make adjustments. I think I mentioned this during the original IT construction.

UtahBeehiver Thank you, I am WAY over thinking some of these steps.

The IT is your guide as well as the previous brick, remember each brick is different and the angles are skewed from one side to the other. So to start, looking at the left side of the arch from outward from the center of the dome. The left side of the new arch brick will have the same angles and dimensions as the right side of the previously laid arch brick. The right side of the new brick angles and dimensions will be determined by the IT. Remember this not linear from left side to right side. The same procedure on the right side of the arch, just backwards. I attached a PFD to help you. I The only consistent dimension will be the angle from the ID of the dome to the OD of the dome which will be the half brick size, ie 9" brick will be 4.5" etc

UtahBeehiver or all - I’m trying to work ahead on the tapered inner arch and I’m stuck over analyzing again. Is there a magic formula for calculating the amount of exposure of the bricks making up the inner arch towards the center of the oven? I keep thinking it should be a consistent measurement (like 2.5 or 3in) but I’m not sure.

Any feedback is appreciated

Thanks for the feedback, I will take it. I was able to get the 3rd course down today. No pics but it was another good day.

Here are a couple tips. Use your best bricks on the back half of the dome. Do interior joint space/alignment adjustment in the front half of the dome (this area is never seen after the dome is completed. Last brick of the day, lay one brick on the next course at center back. It becomes an anchor for laying that course and as you go higher it really helps. Finally keep the tapered arch bring install ahead of the dome course, easier to tie into.

Great advice.
