36+ Pompeii in St. Louis

Re: 36+ Pompeii in St. Louis

Here are a few pics from the weekend.

We did row #6 using my standard wall-o-pavers as supports. Gravity will now be a big factor and I think I'm going to use styrofoam forms. They are foldable (with duct tape) so I'll be able to set it, clean it and then quickly rotate the form in place. That's the idea at least

Up to this point I've not tapered ANY of the dome bricks up but I think it is time to start on row 7.

We had a BBQ last weekend and everyone is very anxious for this thing to be done! Me too.

Merk,
It's been a while since you posted anything. How's the oven build coming along? Always nice to see others near STL have a build..

I'll post a few pics in a minute. Thanks for checking in!

Re: 36+ Pompeii in St. Louis

I've been consumed by St. Louis Blues hockey... but no more So now I expect my oven progress to speed up.

I built a form for the arch out of sandwiched plywood. All screwed together so that I can easily (hopefully) disassemble the form. There is also double cardboard spacers around the wood.

As of Saturday I have done 1.5 courses above the soldiers. Yesterday was stormy (and the Blues were on) so I didn't do any work.

Build is looking great. I'm excited to see another local in midst of a build. I'm just starting into pre-production and have already obtained some good info from your thread (material supplier, etc.). Carry on!

Merk, follow your gut. If you got this from Tom in Fenton, take it back and tell him you want the stiffer insulation board, so it is all the same material. Peace of mind does wonders in the long run.

Thanks Tscarborough

The oven is 41 internal but that doesn't change the PSI much. Still in the same ballpark.

Numbers are one thing... but feeling the softness of the board had me a bit freaked out

Re: 36+ Pompeii in St. Louis

Lets say your oven dome and floor weighs 3000#s complete (It won't). At 36" diameter with a wall thickness of 4", you have a bearing surface of 452 SqIn, giving you a compressive strength of 6.63 PSI on the bearing area.

Unless it is a mobile oven exposed to live loads, you have nothing to worry about.

Re: 36+ Pompeii in St. Louis

All,

I need some advice ASAP

Long story short.. I bought fiber board that seemed comparable to FB Board from Forno Bravo. When I went to pick up the board the supplier had limited supply and I unknowingly got board from 2 different manufacturers. Before I did the soldier course I had run some basic numbers and thought it seemed fine.

Now I know the actual boards I was sold:

*Board 1 (large board): Kaowool-M - Item # Kaowool M, Kaowool Low-Temperature Boards (2300?F - 2400?F Insulation & Structural Boards) On Foundry Service & Supplies, Inc.

*Boards 2 and 3: NuTec Fibratec - Nutec Fibratec

The first board has 20-40 psi compression strength and that seems a bit soft.

Looking at the FB Board the compression strength is 0.5 MPa which would be over 70 PSI (right?)

This full-size oven is gonna be hefty. Sagging into the board would be a disaster.

Let me know what you think.

Re: 36+ Pompeii in St. Louis

Looks great! you cut the floor bricks very nicely!

Re: 36+ Pompeii in St. Louis

That's looking good Merc. After waiting out the weather and having your paving completed the project will move on quickly from here. Will watch with interest, it is shaping up to be quite special.

Re: 36+ Pompeii in St. Louis

Made some great progress this weekend. I'll post more pics later.

Re: 36+ Pompeii in St. Louis

Your project will look great when it is done. I have a big patio to do too but I think I will let it take the back seat to the oven. I'm excited to see your finished product. The oven/hearth looks great. I like that you decided to remove the cement board and go with the plywood. I did the same but ended up leaving mine in place. It will eventually be covered and unseen but it was just a bit lazy letting it sit on the bricks. I guess I felt like being lazy that day. Good luck with your build I'm looking forward to following.
