Aceves's Corner 42" Pompeii Build

[Amac]

Hi Gianni
I never stop being impressed with that dome of yours. It won't be surpassed.
I think I know what you mean by this "droop" . Is it caused by a sort of optical illusiom. I am expecting to have some tricky cuts when I come to attaching the wall bricks to the arch - especially higher up.
BTW I went ahead and cut all my arch bricks identically (well as identically as I could manage with the angle grinder - no tapers so a lot of mortar will be used, but - and don't laugh when I say this - all identically wrong I used a template from a life sized sketch like this attached which illustrates the system I used to get the "correct" pentagon shape.
It doesn't look like much and I could probably work away with it. I couldn't face cutting another set!
Pardon the picture quality - I use the phone cam and bluetooth is handy to upload. I made the red one instead of the shaded pencil version and it changes the angles which are not right angles one gets smaller and the other gets bigger.
Sorry for bugging you guys on that arch stuff. I will need your help later on more critical thiigs - and like someone else said here - I'll make a bunch more mistakes to contribute to the learning process
thanks again

Hi Sharkey

I spent a bit of time thinking about this and came to the conclusion that Amac is right

A convert I don't think it is really much of a deal to be honest. I was looking to make as easy cuts as possible. But it is all very well in theory, but I still messed up in practise, as I said to Gianni above, although the mistake was the opposite of what I described - I have no idea how I managed to do it, but I think I can recover it.

What convinced me immediately and unshakeably was to visualise a completely spherical dome with a completely circular "arch". Then you see immediately that every part of it must be the same. Somehow dividing it in half makes it confusing.

It follows then that many of the problems that show up are actually due to the arch getting "pushed out of its integrity with the dome.

Just remember that once you make the first adjustment the bricks will no longer sit in the right-angle of your IT as you have increased the rate of change of the angle

Good point - I hadn't thought of that. There is always something. It won't come as a shock to me then.


And yes I really must start building - and my own thread - but weather here is still a bit unsettled - and today I am going to look for some tarpaulin and maybe a chaep Gazebo.

Aceves _ I am officially handing back this thread - and my next comments will be on my own - must get a good name mmm...

I agree. Sharkey, the graphic of your approach to building a hemispherical arch with identical segments (you too Aidan) is spot on. This is the approach that I used to build the outside of my inner arch. Where I ran into a boatload of challenges is in designing the inward-facing arch bricks to match both the horizontal and vertical curves of the oven, essentially becoming a convex extension of the dome itself. This is where I believe each brick must be different, and not applicable to arches that are built in a single plane.

Here's an updated photo of my build. Finally covered the roof with cement board and finished all my electrical. Not the cleanest board cuts, but stucco will cover all my errors!

The box you see on the right will house an amplifier and my MP3/iPhone for music. The piece of board on the top left covers a round opening where a marine full-range speaker will go, and below left is an outlet. I will be installing 2 marine speakers (all-weather), 2 outlets, and one switch for my lights. I'll be doing the walls in stucco. Haven't decided on the roof materials yet.

So I have a few extra firebricks left over from my build (quite a few extras actually!).

I decided to "mod" my WFG - Wood Fired Grill - that will be incorporated into my outdoor build of the WFO.

Here's a pic of my "mod": I lined the bottom of my grill with firebricks. The idea is that once I fire up my grill, the bricks will soak up the heat from the fire and keep my grill going hotter, longer. That's the idea, anyway.

I have seen a few grills on the internet that are lined with firebricks, so I'm not too far off course, right?

What do you all think?

Where's the grill?

[aceves]

Hi Les,

It's a separate grill altogether that will sit next to the WFO. You can see it in page 2 of my "Corner Install" thread in the Getting Started section. It's a Santa Maria style grill for steaks, tri-tip, chicken, etc.

It's a straight wood fired grill - no propane, no gas. I'll post more pics with the WFO and the WFG sitting next to each other (right now the grill's in the garage).

Hi Aceves,

I understand what it is, I was curious as to where the grill is. The pic only has the brick. Seems like that may turn into a mess if the food is above it.

Hi Les,

Ah, I get your question... The grill's on top, and per your comment as well as Gianni's comment on my other thread, I might be having second thoughts on the lining of my grill box. You're right, it will make a huge mess. I did think about the drippings when I was lining the bottom, but figured it would be minimal. Now I'm not too sure.
