Somewhere in the slumering suburbs of Stockholm

Re: Somewhere in the slumering suburbs of Stockholm

Yesterday was trouble, me being a pitiful fool. I was busy all the night, so no progress in plans.

Some things in life are not that nice, like going thru your vacuum cleaners dust bag. I think all of us can relate to this matter. Vacuuming up small but inportant things.

Here's the deal, yesterday when i was out fishing and taking photos i did this really dumb thing. I dropped my mobile in to the water between these rocks and it quitely sank down. Fast as **** i put my arm in to the water. I was lucky it didin't go to deep or into an unreacheble opening. In no more then 5 seconds i had the mobile in safe hands again.

I really wasn't in the mood to go straight home and dry it, i wanted some fish! and at first it seemed to work just fine. but later it started to do strange things, and the screen was flickering and turning damp and i could not turn the damn thing off. Battery can not be removed without engaging with tools.

Later when i got home. i managed to turn it off, so i went down to the laundry in my building. Placed it in the drying cabinet and waited. When i took it out and turened it on, it wouldn't go on. Ok, why not let it cool down first, i thougt. Sucess, now it was working! but there were still a lot of moisture in the screen Turned on oven, minimum heat, open door and a vacuum cleaner...

The deal, i ended up sucking up power button and a dust cover.
In the middle of the night i was going thru my dust. I managed to find the power button, reasembled the phone and to my delight the phone was working and most of the moisture was gone. Except one thing, the antenna cable had snapped. Now i'm about to order an antenna cable. So this is why there wasn't any progress in my work.

While this may not correspond all that well to the swedish A-team members (bench drinkers), it might be close enough. This is my way of saying, thank you.

Re: Somewhere in the slumering suburbs of Stockholm

Actually, i dont know the true meaning of it either. In the instructions it said something about the use inside of the oven roof (old cast iron oven). And now i found this information."Including reinforcement chip for kitchen stove." Must be something dealing with extreme heat (offcourse). I heard that cast iron dissipates and keeps heat extremly well. And it may be that it cracks by the shear stress created by heat without the iron filings. Or an already cracked or about to become is repaired whit this. Just a thought.

And thanks for all the instructions. The dome is setting on the floor. I will post more thoroughly descriptions of the oven tomorrow. I'm taking a free day tomorrow. Gonna go fishing The ultimate relaxation, for me anyway. And after tranquillisation i will pray to the ancient Roman goods before continuing with drawing the plans.

The fire clay might work, but without the iron. (i dont know what that is for)

It's for sticking fridge magnets on your pizza oven!

And while i think of it. This might be a good selling point.
Something for the FB staff to look up.

The fire clay should crumble easily and not have the chunks in it after you spread it. If it doesn't spread smooth when applied dry, i wouldn't use it there.
You just need enough to level the cooking surface, no more. maybe like an 1/8 to 1/16 ". You can mix some sand with the clay here, but not required. Both the sand and the clay can be sifted to remove larger pieces with an old window screen if you have one. Again, the only purpose of this layer is to level the cooking surface, so don't sweat it too much.

Are you setting the dome on the floor? I hope that is the plan so you will have room for insulation and an enclosure. it looks like you may only have 3-4" of space around the floor in the pic.

The setup looks good as long as you are planning to set the dome on your floor brick and not outside of them.

Re: Somewhere in the slumering suburbs of Stockholm

That's some interesting information you got there Tex. I like thoroughly conducted information.

Re: Somewhere in the slumering suburbs of Stockholm

I ask because i'm about to spread the underfloor paste. I went to the market and bought something called fire clay. I should have read the smaller print. Translated to:
"With reinforcement made of iron filings. For masonry on iron stove roofs."

The iron filings came seperated in this bag you see in the photo.

The clay was also mixed with small grits about 4mm in size. Perhaps this makes it useless for this purpose.

I also bought a bag of sand and the only sand they had was this sandbox sand. Grain size: 0-3 mm

1. Is this type of sand fine enough ?

2. I also have this refractory masonry and i found this declaration on the web. "Refractory mortar uses a specially formulated dry mortar designed for higher temperatures than usual mortar is capable of. Ordinary aggregates (sand) can not withstand temperatures above 700 ? C, therefore the sand in weber refractory mortar is replaced with heat-resistant aggregates."

Will this do the job ? Without additional sand.

3 Can i use this fire clay i bought today to something usefull ? and with the iron filings in it.

Last picture is what i made today. I cut out the oven floor. loose assembled it and tried the door on. The floor bricks are a little different in thickness. Not much, but i want to level it. And therefore i need this underfloor paste.

Re: Somewhere in the slumering suburbs of Stockholm

two different things. Refrac mortar is a mix of sand, fireclay, cement and lime. Fireclay is :

High grade fire clays can withstand temperatures of 1775?C (3227?F), but to be referred to as a "fire clay" the material must withstand a minimum temperature of 1515?C (2759?F).[2] Fire clays range from flint clays to plastic fire clays, but there are semi-flint and semi-plastic fire clays as well. Fire clays consist of natural argillaceous materials, mostly Kaolinite group clays, along with fine-grained micas and quartz, and may also contain organic matter and sulphur compounds.
Fire clay is resistant to high temperatures, having fusion points higher than 1,600?C, therefore it is suitable for lining furnaces, as fire brick, and manufacture of utensils used in the metalworking industries, such as crucibles, saggars, retorts and glassware. Because of its stability during firing in the kiln, it can be used to make complex items of pottery such as pipes and sanitary ware.
Chemical composition[edit source | editbeta]

The chemical composition typical for fire clays are 23-34% Al2O3, 50-60% SiO2 and 6-27% loss on ignition together with various amounts of Fe2O3, CaO, MgO, K2O, Na2O and TiO2.[2] Chemical analyses from two 19th century sources, shown in table below, are somewhat lower in alumina[3][4] although a more contemporary source quotes analyses that are closer.[5]
Fire Clay Compositions
Thorpe[3] King[4] Shackelford[5]
Stonebridge Eisenberg I Eisenberg II Newcastle 1 Newcastle 2 Newcastle 3 N/A
SiO2 (%) 65.10 89.8 64.7 51.1 47.6 48.6 58.1
Al2O3 (%) 22.2 5.40 24.0 31.4 29.5 30.2 23.1
MgO (%) 0.18 0.09 0.40 1.54 0.71 1.91 1.00
CaO(%) 0.14 0.20 0.37 1.46 1.34 1.66 0.08
Iron Oxides (%) 0.18 0.09 0.40 4.63 9.13 4.06 2.40
K2O (%) 0.18 0.61 2.40 not quoted

The long answer.

Re: Somewhere in the slumering suburbs of Stockholm

I have a question. Is refractory mortar and fire clay the same thing ?

[Southboom]

Re: Somewhere in the slumering suburbs of Stockholm

Oh, i'm sorry about that one. It's a very direct translation of the Swedish word for bench drinkers (A-Laget). I should have thought of that.
A = Alcoholics, Laget = Team
So the alcoholics in Sweden are really the A-team.

I hope that clear any misconception.

Re: Somewhere in the slumering suburbs of Stockholm

That is the only a-team i know.

What is the A-team place.?

Ya know Tex,
I really don't think that they ever actually got a pardon from the US military. That may just be where they are holed up .

Re: Somewhere in the slumering suburbs of Stockholm

As i said, i bought this new light to have it overcast from the roof. I't was pretty much a disapointment. 30 Led's, 900mah, 80 lm. The photo of it shining is at long exposure, so it does not concur with my experience. But accompanied by the other light, it may be of some use.

Once in a decade, i get these bright ideas. The brain works surprisingly good, all the planets in the solar system are all lined up.

What i did was that i took this holder for the Soudal Calofer, pushed out the part that pushes the content out of it's container, Cleaned it up so that it won't get stuck. Now i can fill it with refractory mortar. I noticed that the Soudal calofer has almost the same viscosity as the refractoy mortar. While i think of it, this must have been done by someone before me, like some sort of gun you can load with what ever you wish. Anyway, im happy with my discovery. Now i can fill upp those hard to get gaps in a easy way Hopefully.

Good Night, Cheerfully til im back with more.

Re: Somewhere in the slumering suburbs of Stockholm

First of all, thanks for the commendations tickstrings and Greenman.
Yeah, i might really be on to something.

No fish was caught on sunday. I didn't have the time to fish even though i brought the rod. This might be my own fault. We had a wonderful day. Probably the best day of the summer. Me, my dad and my mum wen't on a bike ride. I have discovered this new place in my near surroundings. Through two Nature Reserves, there is this really nice place. I'll have some pictures of this. And yes, they concern bricks and ovens. I'll share them another time.

We had quite an adventure. First we passed the A-teams place. I said to my dad that this might be the place i'll end up if all goes wrong with my build. He agreed and said, - Yes, probably. While my mom did not. I had forgot the route to this place and we wen't all wrong. Ending up in me carrying three bikes through rocky steep slopes and my old dad saying they were glad to have their own Sherpa. Earlier he also pointed out that he now had understood the full meaning of this trip: To make them suffer and die.

The people bathing at the rocks were much like the reaction of Al's (brickie in oz) reactions to everything i express: Confused and astonished with big eyes and empty on words.

Picture #1: The rocky slopes. While not looking like much, they were enough for me to almost feel the taste of blood. Two cast iron bike's (at least they felt like that). And my, not that heavy aluminum mountain bike.

Picture #2: This is what happens to all Sherpas in the end. I must now concur with all Sherpas being of a superior race. Those Nepalese Sherpas are made out of some though timber. I think it's the high and clear air.

Picture #3: My Father. The boss, the witty one.

So today i have been dog tired. Not to much work. I'll post the progress in my next reply.

While this sometimes turns out to be some sort of blog. I'm sorry if i sometimes get's out of topic. Some may find it entertaining and others not, i will try to stay more close to things regarding the field of ovens in my forthcoming path.

Now on to my next reply and the progress of the oven.
