Andis, i really like your itool, but when you place it, make sure that if necessary you can reach the screws that set those Tee Hinges. From my experiences, you may find that your flaps will catch the brickwork when its time to remove it. A bit of dismantling may be needed. It should work fine!

Hey Russ! You made it though the winter okay then! I too suffered from the frost damage, in a more catastrophic way than your counter. When i can get out there, i'll add the repair footage to my build thread.

Had 200 Firebricks delivered today. That gives me a total of 260 plus a set of arch bricks. Let's hope it's enough.

Went to make a mrchipster style jig for the bench saw and encountered a problem.

My saw, not having a huge blade and having the motor mounted close on the right, looks like it will only be able to cut with the brick placed to the left.
I may have to cut all the bricks in half, then taper one end of each, then reset the jig and taper the other ends.
It looks like it won't even cut a brick in half in one cut but will need the brick flipping to complete the cut.

Unless someone has a better idea

I have not ruled out the possibility that I may be missing an obvious and simple solution having never used the saw before.

Depends on how tight you want your joints i suppose, but you could try a cut as deep as you can then use a bolster and hammer blow from the opposite side of the cut.
The outer edges of the bricks don't really need a clean face, and if your laying with mortar then any slight deviations can be lost. The inner face is all you'll see.

Sacrifice a few bricks if you have spares.

Other wise a second brick jig, which can be set as a mirror image of the other one may work? Especially if your able to remove the brick and transfer it easily.

Weather stopped play... Yet again. Winter decided it wanted to hang around for a bit longer which has kept temperatures below freezing and the oven base covered with snow until this week.

It reached a balmy 20 in the sun today so I grabbed my shorts and tanking slurry and headed out.

It states on the tub of powder that you can apply the slurry with a brush or trowel so I expected the mix to be a liquid. However according to the instructions the 25kg tub should be mixed with 5.7 to 6 litres of water. You can only mix up a little at a time as it goes off quickly and you shouldn't add more water to keep it workable. Even adding a bit more water than suggested still results in something that you could not apply with a brush - imagine trying to paint play-doh!

I have applied a first layer on a small area with a trowel (pics below) and will make sure it dries ok before doing the rest. Providing it looks okay tomorrow I shall give the rest of the inside and floor, and the outside of the back walls two coats.

If anyone else has used tanking slurry and can offer advice I would be grateful.

(I have no idea why photos I upload here via my BlackBerry PlayBook are turned on their side. I shall rotate them 90 degrees in the other direction next time and see if it's fooled into posting them correctly)

That is one heck of a build you have started! That retaining wall looks like it took a ton of work. Keep the pics coming!

Brickie & Gulf -

I am considering going one step beyond your plastic sheet idea and also placing a 1mm aluminium (aluminum if you prefer ) sheet under the oven floor as an extra moisture barrier. Not 100% sure the plastic would stand the test of time but cannot see the metal ever reaching the 660C it would take to melt.
Any thoughts?

Capt - It has been a lot of work. Almost 50 meters of it and still a load more concrete to go. The Mrs is good with the mixer though and I've promised her a new shovel for her birthday.

Might better put a piece of plastic under and over the aluminum, then. The aluminum will not "stand the test of time if it is exposed to masonry" .

I don't think Aluminium is a good choice. It has a tendency to react with lime and more so in the presence of heat and moisture. Water moving away from the heat will tend to hit the cooler metal barrier, condense and sit there. A better solution to prevent water wicking from the concrete base is to waterproof the base which it seems you have done.

Vermiculite cast and board cut ready to go on top so it's time to start cutting the bricks..

The more I think about how the arch will meet the dome the more my head hurts!

If I start cutting the bottom arch bricks as marked in the photo will i make it all the way over without them becoming too thin where I cut in the taper to meet the dome?

No matter how much I look at others photos my head won't get around it. Arghhhh.

The good news is that my cat has passed the work so far after giving it a good looking over this morning.

Andis,

I used this link to another build to help k79 visualize how to make an arch similar to what you are doing to. I see you have an IT so take a look at this thread and posts around that area and it will help. Yell if you have any questions.
