    Well here goes nothing

    I'm getting started to build a brick oven. Just
    Found this site. Don't have a lot of time to
    Research as I have pour planed for next week.
    I built a pergola and patio I'm pouring, and stamping.
    My plan is for a oven just off the pad. I guess
    I'll swing for the fence and do a 42" dome style. I
    Need to dig for the pad this weekend. What size
    Pad do I need for block base? I'll go 10-11 inch deep
    4" stone and 6" pad with rebar. Just need a size. Thanks

    It's enough to get me started. I'll worry
    About getting the extra wool when I'm close
    To done the dome. I got fire clay, sand, Portland
    Cement, and lime! My lime is yard lime but
    That's all Home Depot had?

    Assuming a 4" thick wall, gives an external radius of 25" and a dome surface of 3926 sq/in. which equates to 27 sq/ft. Minus the arch I would say you'll get 2" coverage.

    Check your math. Assume 0.5(3.1416X51x51)=4085 square inches divided by 144 (12" x 12") = sq foot = 28.4 sq ft+/- with no contingency

    Area of dome = 1/2 of 3.1416 x d2 plus some contingency for waste and chimney area with d = 42" plus 9" for brick and plus any other coatings under the blanket.

    Ya I'm looking at that? It's weird heat ratings? I'm
    Not sure how to measure? I need to know the
    Outside sq area of the dome? If I get a roll 25" of
    1" would I have enough to get 3 layers?

    The same place you get the InsulBlok will have the CF blankets too.

    Bubb, you may find uses for the left over insulation. I have seen people use it for insulating the oven door. I plan to use the left over for insulating my stainless steel vent.

    Go to the harbor freight website and look at their monthly add. The 2.5 HP tile saw is on the first page for $264.99. This link should take you to the saw directly.

    Hubert I getting the 2" ins block. Price is 132$ plus
    Shipping. And it's quit a lot of it more than I'll need.
    So I'll sell the rest. I've been all over the Habor website
    Couldn't find a 10" tile saw??? Only little ones 7"? Might
    Run out to store tonight. It's hit or miss with them on what
    They got. It's to be a nice weekend so I'll be doing
    Something on the dome, making my arch tool, forms, layout.

    Bubb,

    Not sure if you are aware of this, but Insblock 19 is available in different thicknesses. The price for 2" thick I was quoted was only slightly higher than the price for 1". I think it is also available in 3" thickness. Depending on what total thickness you want you might be able to save quite a bit with the thicker blocks versus stacking 1" sheets. The 2" sheets I got were 1" sheets lightly glued together and one or two separated during cutting. You'd think they would cost twice the price, but they were only about 35% more per sheet.

    The Harbor Freight tile saw is currently on sale, I believe it is about $260. Not sure if that is an option for you or not.

    Gulf I'm all ears! Thanks guys I'll be ordering my ins block 19 tomorrow. I can get fire clay local, and fire brick. I should get to craft store to get layout paper Tomorow also. As I can't find a tile saw to barrow big enough to use a jig for bevels. I guess I'll go the cut in half use shim method. I don't know there would be any difference once built. You only see those nice cuts while doing it.. I need to search forum on EBAY bought ceramic fire blanket. There is different weights and#? I just know I need 3"??? What's the deal with non ceramic safe blanket? Something new??

    So I plan on small batches to keep it fresh. Would be nice to hear from anybody who used
    More sand?? See if it made a difference for them? Got a lead on the ins block 19 will be enough to do my 42" and another 36" so will be for sale at cost! Just gotta get the blanket insulation. Might check ebay out. Thought I saw some on there cheap!
    Sorry to chime in , I know this was directed to Bubb.
    But, you will need to make much smaller batches than using "shovel fulls" for parts. But, as for as the ratios go, it doesn't matter if you use red solo cups or shot glasses. As long as you use the same size container....

    EDIT: Sorry ,
    After posting a reply, I saw that Hubert had already answered the question. I tried to delete but, it did not work .

    Any reference to "solo cup" is strictly circumstantial .

    Re: Well here goes nothing

    Bubb, I used a plastic Solo cup as my measurement device. I think it is 16 fl.oz filled to the top. 3 cups sand and 1 cup each of fireclay, lime and portland was just about the right amount for me to use up before it started getting too hard. On the lower levels, it was enough for about 2/3 of a course and more the higher I got up the dome.

    I would recommend you start out with small batches to get a feel for how long the mortar lasts and how quickly you are using it. The mortar gets harder to use the older it gets. With home brew, I think it is ok to add some water to reconstitute it and keep it workable. The batch size also depends a lot on how many bricks you have pre-cut. On the first few courses, I pre-cut everything and it took maybe forty-five minutes to use up the mortar. On the higher courses, i spent more time cutting and was struggling to use up all the mortar. If you do not bevel and taper your bricks, you will probably need more mortar and larger batches will work. I'd say start with a small batch and work up from there.
