Modified 3G Masterly Tail Build

Re: Modified 3G Masterly Tail Build

This is all I'm doing for the rest of the year.

I'm cooking xmas lunch in it, so I will post some pics of that.

next steps are to complete the landing & chimney which I will hopefully start in January ...maybe. Lots of other work on the Farm has been put on hold for this project.

Setting up the formwork for the prep-bench


adding the concrete


All done!


bench mockup - it will eventually be 5 courses high, not 4

This sleeper will be the lintel over the front wood storage.



Starting to add the sides...

Re: Modified 3G Masterly Tail Build

Interesting build Mitchamus,i was originally going to do a similar oven but i got convinced to do one with less thermal mass and more insulation but i really like what you've done.
Hey why did you taper the inner arch bricks with a bevel cut?Wont it make it harder to put on a door?

Thanks John. There really isn't that much extra thermal mass in it (comparatively speaking) only 2". (which is what FB recommends for multiple baking sessions)
I'll still be adding 2" of blanket all over, and also filing any left over space with loose Perlite, so it will still be heavily insulated too.

There will also be a thermal break between the oven and the chimney in the form of insulating bricks. The landing will also be isolated from the stand using bricks as well.


Thermal mass is a bit of a taboo subject on this site... As I want to also use this oven for lots of Baking the extra thermal mass will help me out there a lot and save the hassle of multiple firings. I want to be able to make pizza the night before and then cook multiple batches of bread straight away the next morning.

Over Christmas/new year, the oven was constantly hot/warm for a little over a week. I kept a fire ticking over in it most days and overall I am impressed with it's performance so far, even though there is no insulation or even a cover on it yet, heat up time is acceptable for me already, and it will only get better. I have an unlimited supply of firewood. (well.... only limited by laziness! )

Just because I like the look of it...no other reason... It might make it a little harder to put on a door.... my plans are for a Hebel plug bolted to a hardwood fascia that will over-lap the taper.

Gudday
I'm a bit confused on this thermal mass issue.
Your last post you said 2 in or 50 mm mass? Is that 50 mm extra mass on to of the brick at 115mm edge giving you 165 mm or roughly 6 1/2 ins.
That's not a lot of mass actually as lot of ovens are a half brick 110mm with 25mm cladding giving you 135mm or 5 1/2 ins.

Re: Modified 3G Masterly Tail Build

Hi Dave, Sorry - I was speaking in terms of 'added' or 'extra' mass

total mass including the fire bricks:

Floor = 75mm+50mm (extra) = 125mm (5")
Walls & Vault = 115mm+50mm(extra) = 165mm (6.6")

Re: Modified 3G Masterly Tail Build

Ok so made some more progress on the weekend. I started laying the blocks for the side of the oven where the prep bench will join it, and pretty much finished off the prep bench.

Still not decided on the final height of the bench, so decided to stop at 4 courses high. I may lay another half course on top, but it will depend on the thickness of the counter top, which will be concrete at this stage.

I managed to break a block on one side while I was cutting it, you won't be able to see it once the cupboards are in, so I just used it anyway.


anyway here are some pics...

Re: Modified 3G Masterly Tail Build

Looking good.I realised pretty quickly i needed a prep area as soon as i made my first pizza.Unfortunately i didnt have the room to make one.
Somehow I have a feeling though space is not an issue for you

[Mitchamus]

Re: Modified 3G Masterly Tail Build

Yeah there is a lot of space there to be filled up...
Lots of landscaping yet to come... (my back hurts just thinking about it )

Re: Modified 3G Masterly Tail Build

hi guys, long time no post... so here are some more pics on the progress...

Re: Modified 3G Masterly Tail Build

In case you hadn't noticed - we could really do with some decent rain

Re: Modified 3G Masterly Tail Build

So hopefully finishing off the rear wall this weekend.

I'm still undecided on what to use for the oven landing, I have my eye on some granite step treads - two of which will see it finished, but with a horizontal join midway across the landing.

The landing area is a little smaller than 1200 x 650.

If not for the cost, I would just get a rough/natural edged piece of granite cut to fit in there. something like the pic below...


The problem will then be getting some decorative bricks to match the stone landing.

Re: Modified 3G Masterly Tail Build

Mitchamus,

Loving the dialogue and the build. I am in the planning stages to do a barrel "homebrew mix" style oven. Could you please let me know your cladding recipe? Is it the Rado mix or did you create one. After all my research, I have found your method of adding the 2" cladding on top of the vermiculite to be sound. I plan on incorporating the technique onto my build.
Also, are you planning on adding an additional 2 to 3" cladding on top, then on to blanket insulation?

PS: Have you thought about making your counter out of cement, sand, superplasticizer,etc. (the GFRC method) You can create the ridges, similar to the image, add some color and it will look like granite or natural stone, giving you creative freedom and saving you some monies.
