  • Re: 36" in Seattle

    My first and second attempts at "bread", which I put in quotes b/c the bread in question is premade bread, bought frozen, thawed, then shoved in the oven. I think that first bread might be a tad overdone but the second one is pretty good. I waited longer after pizza to cook the second bread.

    Please don't point out that I'm not supposed to have coals in the oven when I bake bread. I'm well aware, but I have no way to get rid of coals yet. I need a metal "pan" of some sort to receive coals as I rake them out of the oven and likewise I need some place to put the coals once they come out. I have neither of those things yet.

    On the plus side, the pile of coals isn't necessarily growing. From one pizza fire to another I can cook the coals down to a pile of the same size each time...which means I don't theoretically need to ever clean out the oven, unless a certain food (like bread) requires it.

    Cheers!

      Finally framed and "poured" (via shovel) the third and final terrace. I actually framed it (hardibacker) last weekend, but wanted to cook more steam out of the exposed InsWool before covering it up, so I didn't fill in the vermiperlcrete until this weekend.

      65:65:13 quarts of vermiculite/perlite/portland (5:5:1 or 10:1 overall). That's about 4.3 cubic feet of vermiculite and perlite.

      I did the two lower terraces 8:1 but went 10:1 on the last terrace for three reasons. One: I was worried that I was running out of portland, two: most of the heat goes straight up so if I am going to use variable insulating values, it may as well be more insulative on top, and three: the higher terraces don't need to withstand as much force as the lower terraces (the concrete can be weaker).

      The photos shown that I didn't perfectly level the fill, but rather left a smooth lump in the center. The two lower terraces are the same way, sloping up toward the center of the oven. The intention is to help water flow off the planter beds.

      Also shown are the bricks that will comprise the sidewalls of the planter beds. Standard pavers are considerably thicker than I wanted so I'm slicing up these super thin slabs instead. Not sure if my HF DiamondLife blade will last (it's only the second blade of the entire job and I did a lot of cutting), may have to get another. Sigh. HF is kind of far away.

      Cheers!

        Keith, in response to your wanting a pan to rake the hot coals into, I use a large aluminum dust pan. If I remember it came from Home Depot and wasn't too expensive. As to a place to to put the hot and still burning coals and lumps of wood: I use a standard roll around type BBQ. I just pull off the top grill and dump the hot stuff in. If I'm trying to save the coals for future use as charcoal then I dump them into a wheel barrow filled with water.

        Using the grill/BBQ allows me to return the coals to the WFO should I wish to smoke something like a pork shoulder using retained heat following a bread/roll bake.

        Hope this helps,
        Wiley

          I have not weighed in for a while but its nice to see the northwest pizza lovers showing their colors. I still fire the oven every two weeks or more in our rainy climate. I wondered if I'd still see Wiley. Nice to see he has become sort of a fixture on the site. We started our ovens about the same time

            I'm gonna give a shout-out for Pacific NW builders. We too have been using our oven over the winter. We're excited for Spring, summer, and fall. Our winters are not a magical winter wonder-land, but more of a dark, dank, cool, gray, wet...

            It's been a real pleasure checking-in on your progress Kebwi. I'm really looking forward to see how your interesting finish takes shape.

            Cheers!

              Kebwi,

              I just had a thought that might not have much merit, but...

              I've seen in a couple of your photos what appears to be a very large amount of coals. I usually only have about perhaps 1/3 as much in my oven at any given time. I mention this because I can't help but wonder if the bottom rows of your sphere are difficult to go white because they are being insulated/shielded by the mound of coals. Relatively speaking, coals offer a lot of insulation from a live fire.

              Just a thought. I was thinking that if you put in less fuel in at a time, but at a higher frequency of additions, you could possibly keep the coal bed height down. Might be worth a try???

              'Can't wait to see those terraces take-on there own!

              Cheers,
              Ken

                Keith,
                I am intrigued by your terraces, very innovative design. It seems that if your insulation is stout enough then you can plant native plants that will weather the NW climate, if you have some heat leakage then some less hardy plants will survive. A win-win situation( though you may have to fire your oven to keep the plants alive in the second scenario).
                Very thoughtful, unique design. If James were doing build of the month I would nominate you. Nice job. Now you just need to learn to cook, since you have an artisan oven. Send off to Sourdough.com for some starter and begin to figure out bread. It is a whole new challenge. And you are always welcome when you bring fresh baked bread to friends house.

                Great job!!
                Eric

                  Thanks all. Lots of advice to take in. I'm not too worried about the oven "cooking" the dirt. I have fired it enough times to learn how it behaves and while the top of the exposed InsWool would warm up some, the top of the filled in vermicrete basically doesn't heat up at all. I think the plants will be fine.

                  As for oven of the month or whatever...sheesh, I haven't finished it and I'm still scared as hell of all the work I have left to do...but thanks for the compliments. We'll have to see how it all works out.

                  ...and lots left to learn on how to book and bake too, I'm just getting started, although the bakeries around Seattle are very inspiring. There's some very good food here.

                  Cheers!

                    I cast my own lintel- would do the same again. see Lintel 3 - Build Your Own Wood Oven

                    I found i could make a right angle bend in 1 inch cold rebar using an engineers vice. I was very surprised how easy it was to bend.

Also put an extra 3/8 inch rebar in an "L" shape around the "weak" corner. I would make the suspended slab at least 4 inches thick with all rebar near the middle vertically.

                    Rebar is cheap.

                      Wow, that's an old post. I'm pretty far past that crazy lintel. My slab never settled, not even an 1/8" of an inch, over the course of the entire build. I know it didn't because immediately after pouring the original hearth, I put some dry-stacked concrete blocks under the center as a support pillar. The last blocks slid in with maybe 1/16" clearance, just barely shakable at the right angle. Well, four months and 2000 pounds of firebricks later, those blocks are still loose, so the hearth never settled down onto the free-standing pillar.

                      Just sayin'...

                        Parged the lower two terraces 4:1:1 sand/portland/lime. I'll do the top terrace tomorrow. My reasoning for doing this is two-fold. First, the vermicrete is very loose in some places, like a full half inch of loose rubble that I can dig through before hitting a hard concrete. Not everywhere, not over the entire terrace area, but in a few places it's that bad. Two, by smoothing out the working surface, I'm hoping my SBC will go further. I would hate to run out.

                        Also shown are a pile of little bricks that I'll use to make the walls of the planter beds. They are quarters cut from the large flat slabs shown in an earlier post.

                        Cheers!

                          Hey Kebwi, I found this old pic this weekend. It is an SBC castle I built for my daughters when they were little. It is drystacked CMU and the crenelated turrets are bricks, kind of like what you are doing. In the 5 years of many small children swarming the castle, none of the bricks ever broke loose, if that makes you feel any better.

                              Parged the upper terrace, 4:1:1. Also mortared a few small pieces of hardibacker to the vermicrete where they had fallen off after the initial terrace pours (pieces that were too small to justify a bolt/washer lock). All in all, a slow weekend. I threw my back out last week so that prevented me from doing almost any work. Oh well.

                              Cheers!

                                OMG, Keith. Your brickwork is FLAWLESS. Next time I build (if there ever is a next time) I'll try to make mine as precise as yours. Simply awesome. And the design... what can I say but very inspiring!
