39 inch Pompeii in Lincolnshire England

Re: 39 inch Pompeii in Lincolnshire England

Brickie, I looked at a LOT of places for a blade.

I have accounts at a few builders merchants and tool suppliers.

I also tried fleabay and the online suppliers.

250 mm with a 1 inch bore is difficult to find at a lot of places here.

It is half the price for me to get a segmented blade sent from the US even with the postage and import duty included.

It's just one of those things. Tools are cheaper in the US, camping equipment is cheaper in OZ, Beer is cheaper in Vietnam and everything is more expensive in the UK

Nice toys!

i used to be a landscape gardener, and always look back fondly to that time.

What brick saw do you have?

Re: 39 inch Pompeii in Lincolnshire England

Had a look about for a blade today.

10" 25.4mm bore segmented diamond wet blade ?144 ($218 US / $238 AUS)
10" 25.4mm bore non segmented diamond wet blade ?18

It might not be ideal for the job but at a saving of 87.5% I will give the cheap one a shot.

You must have looked in the wrong places for a blade?

Re: 39 inch Pompeii in Lincolnshire England

That's good to know before I start cutting with it.

If i get results like yours I will be a happy man.

Looks like I could have to abandon the build for a while once again to landscape my driveway and garden

At least I get to play with a digger and dumper for a couple of weeks

Re: 39 inch Pompeii in Lincolnshire England

I used a non-segmented blade for my entire build, no problem

Russell - I pinched the chimney pot from my dads garden.
He has a few and most are a lot older and ornate so he won't miss this plain one.... And it matches the others on my house.

Bookemdanno - your drying out too quickly idea seems to fit. The mortar on the dome bricks seems ok and these bricks had soaked overnight. The mortar on the left arch has gone powdery and the brick dropped off as I touched it. This brick was only sprayed with water just before being placed.

I will soak all bricks overnight from now on. I have been putting a damp sheet over the brickwork when I am finished for the day.

The premixed seems much stronger than the homebrew so I shall use it for my arches and chimney support.

The old blade on my saw was struggling today after cutting another 80 bricks so i am off to get a new one in the morning. Getting a 10 inch segmented blade here in the UK is very difficult. I will have to make do with a solid ceramic blade rather than wait a week for a segmented delivered. You guys in the US and OZ are spoilt when it comes to tools and blades for this job!

Neat chimney pot ur using for a chimney.

Re: 39 inch Pompeii in Lincolnshire England

Is this mortar in the brickwork or just bits lying around?
If its within your brickwork, then usually that is due to the mortar drying too quickly through the bricks sucking the moisture from the mortar before it gets to cure. There is a chemical reaction that needs to take place. If your adding dry brick dust to the mix too, its a good chance that dry bricks and this added pozzolan is just too aggressive a mix, and causing the mortar to dry too quickly. Its seems a rich mix too. I'm not au-fait with the homebrew exactly though. I'd say that you'd need to hydrate the brick dust before adding to the mix, by creating a sludge and then mixing into your mortar?
Are the bricks you've laid still in place? Give them a tap with the butt of your trowel.

Not firebrick experienced either, but the fur sounds like efflourescence.

Re: 39 inch Pompeii in Lincolnshire England

The ready made mortar I used at the start has dried solid - but my homebrew is drying powdery and turns to dust when handled.

I made it 1:1:1:3 as seems to be standard.

Is this powdery result normal?
Should I up the portland ratio?
Do i return to using premixed?

Also my Firebricks are growing a white fury jacket as they dry out.
Is this just salt drawing out?

Just cutting today until I get some advice on here about the mortar.

Re: 39 inch Pompeii in Lincolnshire England

Sorry Andis, i had my head on upside down! Less off as you go up the arch!!

That's a pretty good start, and not such a great start with HWMBO!
Have you not had the "you spend more time with that oven" comments yet?

Re: 39 inch Pompeii in Lincolnshire England

Third chain finished. That's all I had cut and i didn't want the neighbours listening to my brick saw all Sunday afternoon.

The arch tie in won't be as neat as some but it's solid, and it's no pig, so i'm happy.

I have a 450mm chimney pot that I am going to use. This will be above a ceramic flue liner, housed in brick, to get me from the vent to above the roof on the house. They are both 9 inch diameter.
I hope this will work ok. I was worried about the weight but I plan to buttress the arches by building either side inside the house walls.
If this sounds unreasonable then please tell me soon as I am on a roll.

LMAOROFL !!

Tip - I took the metal sieve from the kitchen and ran the dry dust from the brick saw tray through it with a spoon. The result was a nicer homebrew with no annoying gritty lumps.

Second tip - ask before you take the sieve from the kitchen to use as a builders tool the day you have people coming over for dinner.

There are countless ways in which the building of these ovens tend to "annoy" the other half . Tip #2 would probably irritate the sht out of just about any of them .

Re: 39 inch Pompeii in Lincolnshire England

No more arch cutting yet. Laid a few easy ones before being rained off yet again.

Forecast for the next few days is good so I will be doing nothing but cutting and laying bricks. This week should see some faster progress.

Re: 39 inch Pompeii in Lincolnshire England

Andis,
As you figured out top arch brick will be the longest. The template approach gets you a rough idea but each of the brick angles change as you move down the arch. Use our IT to help you set the angles they move in all three axis. Spend some time here and it will pay off during tie-ins.
