Re: Michigan Build

Made more progress on my dome over the past couple of days. I lost a couple of brick seam staggers...I expect some cracking for that mistake.

Re: Michigan Build

Has anyone ever seen one of these? I was cleaning out my Dad's garage this spring and came across this. The person who had the house before him left it....over twenty years ago. My Dad thought it was a rock tumbler and the guy was really into rock polishing. I knew what is was when I saw it and thougth I would see if the motor still worked....sure enough it works great. I have been using it a lot. Too small for mixing for a pad but great for mortor, and filling the block cavities. What a neat little mixer....does about a 60 pound bag at a time....

Made by MAN-U-FAB ? 3025 Bailey Road, Newport, MN 55055

The still sell a complete line of small mixers.

Re: Michigan Build

Working away at dome construction. Got through the 4th course and going pretty smoothly so far. No major issues yet. Love using the IT instead of a form. Really like the ability to clean the inside as I go by using the IT. I opted for using the half brick without tapering or beveling the edges in the interest of time. So far, I am not dissapointed. However, I understand gaps do nothing but get bigger from here on so I will monitor it and see what I can put up with.

Re: Michigan Build

No....I just ran them wild when I laid it out. I plan to cut them back so I can insulate properly.

Re: Michigan Build

Is there any reason why your hearth brick layer extends so far from under the dome walls ?

Re: Michigan Build

I was able to use a 10" wet saw to make the individual cuts. It does make the build significantly slower. I was only able to pound out one chain a day (I was admittedly very slow). My cracks are minimal, and I have no regrets. Having said that, no one ever looks inside my oven. Many builders use half cut bricks (perhaps 1/3 as you get to the upper rings) with no problems. Just be sure to really stagger the vertical joints. That seems to be when most builders get into trouble with significant cracks.

As far as the insulation, it shouldn't get wet. A little wet mortar splashing on it is OK, but cover it at night from the rain until you get it permanently enclosed.

Re: Michigan Build

Looking great! Can't wait to see the finished product!

Re: Michigan Build

Today I finished the first course and completed the arch.

Question: As I move to the second course I have a decision to make if I am going to try and cut each brick to get a "Les-Like" tight fit or if I just go with simply using half bricks and lots of mortar. I only have a 10" wet saw. I know this has been bandered about on this board but I get the feeling most just use half bricks and it will be okay from a structural perspective. Anyone have any advice for me? BTW....it is September now and I live in Michigan....so I am really trying to get this project wrapped up by Halloween......but I have invested a significant amount of $ and time to this and I don't want to skimp either. If it really makes a difference I would rather tarp it up for the winter if I don't finish it and complete it in the spring.....thoughts?

Re: Michigan Build

Got back into my project over the holiday weekend. Got my Insulation down, the oven floor laid, my arch form build and in place, My IT built and positioned and the first course set. I feel like it was a productive weekend and it is starting to look like something.

Question.... Since I set the insulation board I have been covering it for fear that moisture would damage the insulation. True?

Re: Michigan Build

Picked up the cement mixer and ready to go to work. I had some blocks to fill along with pouring the 4 inch pad. According to the bag it would take 30 60 Pounders. I had 8 left over from before so I figured I would be good with 30. I was wrong. I used the extra 8 plus I had to go out and get an extra 10....mid pour... I poured from the mixer into 5 gallon buckets and hoisted them up onto the hearth. What a great workout! I didn't have any help so the cement started to fire before I was ready....that along with the delay of having to get extra bags made it a bit tricky. The finish was not perfect but it was level and flat....I guess that is all that matters.

Re: Michigan Build

On Saturday I got the base prepped for pouring the hearth. Some things of note: You will see the two flues coming through the hearth for the fireplace chimney. You will also see a PVC pipe coming throught the hearth. This is intended to be a passage way for low voltage lighting wires as I have run them to the base for accent lighting. I made this passage a little larger so that it could also be used for any other items I may think of during the process. Remember that I will have access to the back of the lower base through my walk in storage area. I have also run a gas line to this structure so I could do some gas lighting or something if I choose....you never know. Finally, you will notice two angle irons protruding out the front of the hearth. This will serve as mounts for a "floating" fireplace mantel which will me made of granite.

Re: Michigan Build

My design is a bit different than most. For one thing the structure was designed to be built into my patio. The patio is about 18" high where the Fireplace/WFO will be. Therefore, the back of the structure is quite tall. This provided me with an idea. I decided to frame a doorway in the back and have a "walk in" wood storage area. The typical wood storage area in front is not available because I am using it for the firebox. I plan to make a door and also store my tools (rakes, brushes, peels and the like). Will probably put some shelving in or a rack at a minimum. Anyone see issues with this plan that I may not have thought of? What types of things besides those I listed about should I plan to make room for in this space?

Re: Michigan Build

Okay....made some progress over the past few weeks...also took a long weekend off from the project to take the family to Mackinaw Island. Anyway, In previous posts I described the smoke chamber I was building to catch the fireplace smoke and direct it out through the two chimneys at the top of the firebox. I finally got that built and lined with firebrick. Also attached the two clay flues which will eventually join together to form one chimney out the top. You can also see my helper Max....

The second picture is a view of my smoke chamber cladded with firebrick. The two openings are the two clay flues. This picture was is a look from inside the firebox from the firebox floor looking straight up. I plan to do the rest of the firebox in a harringbone pattern but up here where nobody will every see it I laid the brick straight....luckily I thought to do this from the top before I closed it up...much easier that way.

Re: Michigan Build

Looks great so far!

Of course I know where Macomb Twp. is.... I grew up there!

Your photos look like familiar neighborhood, which is why I asked.

Looking forward to your build.
