Default 42" in Portland OR

After being a mooch for so long, I finally have something to post to the forum. I have started my 42" build in Portland, OR... going to be doing some wet-weather construction shortly.

We had a couple of nice weekends, so I tried to capitalize on them as best I could. It turns out planning is not my forte... I was tying the last of the rebar together as the concrete truck was pulling into the driveway! It was my first time working with concrete, and I am glad that it will be hidden by the oven stand.

I have shamelessly copied from the wealth of information on this site, and have modeled my stand after others on here. I have a wood storage area in the front, and a shovel / tool storage area in the back.

Finally got the hearth poured, cured, and the form removed. Boy is that a great feeling - being able to stand on a piece of concrete that I poured. My wife was definitely surprised how big these things are...

Were I to do it again, I don't think I would try to use the little mixer for the hearth pour. 3200 lbs of concrete gets a bit tiring when you are lifting it multiple times (into the car, around the house, into the mixer, from mixer to hearth). Who needs a gym with hobbies like this?

I'm impressed! I mixed 2 bags of concrete in the "little mixer" for my hearth slab and then immediately went to the phone book and called for the delivery of a yard of premixed. Guess that I'm too old for the gym or that much manual labor.

You might want to consider putting in a thermal break between your enclosed oven and the landing bricks. It doesn't need to be very wide, but it seems that many here on the forum highly recommend it.

Are you going to build a cover for the oven so you can use it during our rainy winters?

Aaron,

Good start, keep sending pics. You borrowing other ideas is just mode of operandi on the forum. Why reinvent the wheel. I did my share of borrowing!!!

Thanks for the replies - the thermal break is definitely in the plans.

UtahBeehiver - did you have any issues with the depth of your landing? I was hoping for a shorter one, but had kind of wound up with a 14" to accommodate the 8" duravent pipe (with 2" to support on either side)

Am I missing something here?

Thanks!

You can get it down to 12" if you are creative with the way you build it. That's how deep mine is.

If you set the flue pipe further back you should be able to get it even shallower. The pipe can be slightly behind the oven opening provided there is enough funelling to the pipe. My view is that a shallow entry is a big advantage when you are working the oven. But you must make sure that it is adequately flued otherwise a shallow entry is more likely to leak smoke out the front.

My entry is only 5", add another 3" for the outer decorative arch. But the oven internal is only 21" in diam. With a 5" flue pipe.

Aaron,

My is abt 14" landing on a 42inch ID oven. I think an 8" anchor plate is 12x12 so you need to factor this in. Good luck.

PS I opted for a larger landing with an inset decorative arch to minimize smoke coming out the front. Karangi Dude gave me insight on this.

Thanks for all the encouragement. I keep telling my wife that I'm not crazy with this project, but she doesn't quite believe me.

Made some progress this weekend - got the insulation cut, laid and leveled the floor, and mortared in the first sailor course. I was using the "fine" sand from Lowes in the homebrew mix, but decided that it was not actually fine enough for the higher layers. Going to pick up some #70 Dolomite (?) sand in the morning - I assume that will allow for a finer grout line?

Ignore the mess - those leftover pieces of wood are protecting my feet from the Pacific Northwest mud. Of which my backyard is producing a bumper crop.

go to your local concrete/masonry supplier and ask for fine sand. Stuff at lowes is brickies sand, has too much aggregate in it you need to sift.

Fine sand will let you get those fine grout lines

Understand about the better half thinking us crazy or the the WFO is our new girlfriend. But in the end they love the pizza, bread, and roasts. One hint, cover the gap between the second course and floor with duct. This will keep mortar from getting into the expansion gap and hopefully preventing stress and cracking. BTW, most everyone will see a crack in the oven somewhere. Keep up the good work. I used a quartz sand for my home brew.
