Added the decorative arch to the front of the oven yesterday. I have confirmed that I'm not a mason and that buying a modular oven was the right approach. Haven't checked this morning to see if the arch is still there or if it will still be attached once the form is removed. I'm going to try to add a bit of mortar in to some of the joints to make them look a bit more consistent if it stays in place. Here's a picture, there won't be any close ups, lol!

Default Re: West Virginia Casa90 Build. First Fire

Received the 24" section of chimney I ordered so was able to add the chimney to my build. I have 6' of chimney pipe and this gets the chimney about 24" above the roof of the pavilion. Not sure why I originally thought I would need two 48" pieces of pipe but got it right this time. I've posted an ad for the extra 48" duratech duravent pipe in the For Sale forum since I won't need it. As FYI, I ordered the pipe from buildit.com on Wednesday and it arrived here on Friday with free shipping- hard to beat.

Here's a picture of the chimney after install. I have one bracket securing the pipe to the facia of the pavilion.



Since I had the chimney in place, decided to light a small fire, burned for a few hours, only a few small pieces of wood. Outside of the oven was about 160 degrees, inside about 220 or so measured with an infrared thermometer. Let it all cool down and then covered the oven with a tarp.

Will have to research the process of starting a fire, thinking the easiest way will be to light some kindling near the entrance under the flue, then push it back in to the oven after it gets burning. My wood might have been a bit damp but had a bit of a time getting it to light off when it was further in the oven. I was happy with the small amount of smoke that escaped out the front once the fire was burning. I'm assuming that with a larger fire, the flue will draw even better.

I'm going to do another small fire before I start adding the insulating blankets to at least make sure that I don't get any obvious cracks that would be easy to fix while the oven is uncovered. We've had a lot of rain here and the humidity is in the 70-80% range so really damp. I'm waiting for a clear and dry forecast for a couple of days before I try the first coat of stucco.

Here's a picture of the first fire. Almost cooked a smore for my wife but decided to wait, lol.

Fires can be difficult in a damp oven so do not be frustrated yet.

Since my oven is fully seasoned I take two pieces of wrist diameter wood placed parallel about 6-8 inches apart, fill the space with crumpled newspaper, place kindling 3-4 across and then 3-4 more in parallel.

Then I light the paper, starts every time.

Once the fire is burning I push the pile to the middle of the oven and add more wood. Sometimes it is easier to push it back if I use a medium sized piece of wood that spans the two larger pieces using it to push everything at once.

You may want to do your curing with charcoal, kingsford works well because it has those little fire enhancers in it.

Default Re: West Virginia Casa90 Build, Fiber Blanket Installed

Covered the oven with 3 layers of the FB fiber blanket this morning, then used 1/2" hardware cloth to form the dome shape. It looks pretty rough but it's a rustic oven, right?

Here are a few pictures as I progressed.







First coat of stucco came next, pictures in the next post.

Default Re: West Virginia Casa90 Build, First Stucco Coat

Here are a couple of pictures of the first coat of stucco over the fiber blanket and hardware cloth. Think the mixture was okay but one batch was a bit wet. I used a mix of 1 part portland, 1 part lime, and 5 parts sand for this coat. Will post a new thread with some questions on how long to wait before putting on the second coat.

First picture is mixer and materials ready to go.



Next shot is when I was almost done- should have stopped to take a picture or two along the way but forgot.



I have fired the oven with small fires 3 times so far and no issues to report with the oven itself, hopefully any cracks in the stucco will be small. There were a couple of places where the coating was a bit thick when the hardware cloth shell stuck out from the blanket a bit but hopefully it will cure in one solid piece.

Thanks for looking

Dave,

Looks good so far! It appears the end is in sight. I should be starting my oven soon and I'm grateful for your pictures and posts. I sent you a PM in regards to your stucco question. It seems that DRYVIT is the way to go and a lot of home builders use it down here in the swamp. I am actually concerned about the moisture/rain down here as well. Sherwin Williams makes this product (Loxon XP Masonry Coating) and it is a 1 coat system with no need for priming. I wonder if anyone on the boards has used any of these products and could offer some guidance.

Keep up the good work!

Kenny

Added a second coat of stucco to the oven this morning. Here's a couple of pictures showing one area before and the same one after. Will be checking out a final finish product next, kgator, thanks for the comments. Once this coat dries, will get a close look to see if I think it needs a skim coat or something but so far, I think I'm happy with the shape and finish- a few dips and bumps but hey, it's home made!

With no guttering on your roof, a lot of rain will be directed straight down onto your oven, especially where the flue pipe penetrates the oven. you may need to rethink this problem.

Agree. A builder friend is supposed to be leaving me a piece of aluminum flashing that will be placed at the bottom of the roofing to deflect water away from the oven. If he doesn't bring me the green painted flashing to match the roof soon, will have to rig something up myself. Maybe I should do something temporary for now.

david s.- your note, and the forecast for showers overnight prompted me to put up a piece of metal edging above the oven to see if this will help at least until I can do a more permanent fix. This is a piece of metal meant to go on the edge of the roof mounted under the roofing material and hopefully will move most of the water off to the side of the oven.

In the picture, the metal looks like it matches but it's actually a different green from another barn project of mine but should let me know if I'm on the right track. Thanks for the push!
