IMO, before accepting the challenge, you should have established precisely by how much your beer ration would increase. Missed out there Mark.

Cosi commanda Turandot. ahem... The weather has broken and the ice has started to thaw in the pond so I now have no excuse. The efflorescence has been busy. I've given the brickwork a stiff wire brushing to clean up.

This is a diagram of the arch construction giving the names for the components. Terry will correct me if I am in error on any of this... This is a Segmental Arch with a 90 degree Turn and 45 degree Spring. Not seen is the Abutment to the Pier which takes the sideways thrust of the arch. The distance between the bottom corners of the Springers is the Span and the distance from the centre of the Springline to the Intrados (inside face) of the keystone is the Rise.

The tiling of the oven floor is complete. I've re-grouted and here you can see I'm desperately trying to earn my beer by accelarating the setting with a metal halide lamp. (Will I come a cropper doing this?) I tried a 1200W ceramic fan heater which raised the temperature of the back wall by 30 degrees but it just blows all the heat out. With the lamp I can direct a more intense heat onto the floor. You can also see I've wodged (technical term) the front of the CalSil/tiling overhang with weak vermicrete. The landing will drop to the level of the base slab at this point, lined with more quarry tiles.

Mark The oven is looking good - top idea with the lamp, too.

Love it Mark. The photo with the component "terms of art" is great.
I'm thinking of blowing it up, framing it, and putting it on a wall. It's downright artsy.

I think I have quoted or generally referred to the following build waaaaay to many times but I think its great and was the final motivational build that got me well onto the road. I was going to build a clay oven initially..... Oh the dangers of forums with all these crazy ideas.... ;-) fornoeconomico.blogspot.com/2008_03_01_archive.htmlbut the reason I posted it was he used a similar lamp to very good effect drying a whole clay oven from the inside, in one pic you can see the ring at the top which has dried more than the rest, he had no issues and I doubt you will either.

Thanks for the complements chaps. Turkey, I hadn't seen that build before, thanks for pointing it out.

The more I use these materials the more familiar with their properties I become. The wet air-setting cement is good stuff when used in dry air. It seems to cure faster than a Portland mix, becoming hard and resistant to wire brushing in two days. But in damp weather it can remain soft for a week. The aperture arch is complete. It is constructed over the quarry tiles so I don’t need to faff about with roofing tiles to raise the height of the pier as I did with the main vault. Feeling more confident with arches I used a single chipboard form. I expected this to be quite easy given that these are half-bricks in a smaller arch. In fact, half-bricks seemed harder to work with. The skewbacks I cut from Firebrick as they will be visible, albeit about 10-15mm of them. The aperture is 470mm wide by 195mm high, @62.9%. The arch overlaps the main vault arch by only 6mm so I have reinforced the join using wedges of roofing slate. Getting a flat face to the arch was a nightmare. I have managed to get all the faces flat to within 1mm to provide a neat reveal for a door. If I were to do this again I might try constructing the arch face-down on a flat surface, lined with paper, without mortaring the keystone. Then presenting up the two halves to the main vault and dropping in the keystone. This might have been easier and made for a mirror flat front.

Very pleased with myself, I lit a small fire. I started it at the front with some birch twigs and gradually moved it back, adding larger cuts. Over half an hour I raised the temperature of the ceiling of the oven to above 300'C. There was no groaning, hissing, steaming or cracking, so I think the slow cure of the lamps and the dry weather have helped drive off most of the moisture. At times it was possible to see an inversion layer 10-15cm off the floor where the smoked seemed to float.

I touch my forelock to you sir! You have persevered through the bad season and you have constructed a beaut! Well done! Beer o'clock!
