42" Idaho spud

Re: 42" Idaho spud

Anything worth doing is worth over doing. At least that is my thought.

Re: 42" Idaho spud

Not sure if there is such a thing as an 'over insulated oven'. One of the things where more is better.

Sounds good to me, Alex. Of course I live in sunny SoCAl where it never gets below 34F, but a lot of builders in the midwest (MN, MI, WI etc) have reported great results from exactly what you plan. I have read reports from outsiders who feel our ovens are grossly over-insulated, and they very well may be. But you can't argue with your plan to enclose and fill the void with.... more insulation.

You may be happier with 4" of floor insulation than 3", JMO.

Hey NC and John, thanks for the replies and assurance. Of all the builds to steal ideas from, yours -John - ranks supreme!

Lean towards over-insulating and post lotsa pics

I plan on at least 3" of insublock 19 under the floor, more likely I'll do 4". The dome will have ceramic blanket and loose vermiculite all inside a framed enclosure. That should be sufficient, yes/no?

Welcome, and great start, Alex.

A great many builders here never laid a brick a before and ended up with beautiful, top-performing ovens. It will help if you plan your oven out first, especially the entryway and flue gallery, as this will define your insulation and brick footprint. Easier to fix on paper than otherwise, I say.

And there is no penalty for borrowing any and all good ideas you find in others' builds here. Lean towards over-insulating and post lotsa pics.

Looking good, Alex! As you know, there are lots of friendly and knowledgeable folks on here that are more than willing to help you if and when you need it. Best of luck to you. You'll do fine.

Hey! it looks like the pics showed up. Not sure if people like the embedded format or the thumbnail approach. Not sure I know how to do thumbnails anyway.

I know some may have noticed that I have 2 lintels. That's because I want a storage area in the back for the fire pit I made last summer that's in the background. It will hold all the trashy wood that we burn just for fun. The front compartment will hold the nicer hardwoods for the oven.

Also, I'm sure some will point out the vinyl fence to the left of my oven stand. I checked with the local fire dept. After a huge run around and no clear answer, the fire marshal said that he's heard of people putting these things inside their homes so proceed at my own risk. We haven't had a single issue with the fires from the fire pit. Nonetheless, if I get too concerned about it, I can build some sort of non combustible fence as the fence is entirely on my property.

I'm looking forward to building this and I hope to garner the insight and help from so many a great craftsman on here. Was hoping to get the hearth slab poured this weekend but looks like high winds and rains are in store and I'd rather not risk it. Oh, incidentally, I failed to mention that the lintels were also poured using Quickrete High Strength (5k psi) concrete. I've used it before with good results and plan to use it for the hearth. All that being said, I really don't have any brick experience and will essentially be making this up as I go and hopefully learning a few things while I'm at it.

Thanks, Alex

Like many people on here, I have been lurking for some time all the while scheming about building my own WFO. Last summer I was able to pour the pad and then an unfortunate ankle injury took me out of commission. Well, it's spring and the ankle is mostly better so I thought I'd give it a go. This is my first attempt at posting photos so I'll have to see how it works out.

Here's the pad and the first course lay out of the CMUs:

Next I framed up the lintels and incorporated 4 pieces of rebar. The pic only shows 2 but the other 2 hold some vertical pieces that you'll see in the third pic:

Here's the front lintel with the forms removed:
