Ok I have a question about the chimney.
Do most people line theirs with a metal (is it stainless steel) flue? If so, what are the reasons/benefits of doing so over just a brick chimney? And how have most people fixed it in place?
Cheers, Duncan

This is not my strong point, but here's my twopenethworth....
I create my vent aperture on the entrance arch by building a half brick arch up against the internal fire-brick arch. (it is a good idea to cut a 10mm piece of fireboard which will then be sandwhiched between).....the next full brick arch. I start off with full bricks, but for the top 3/4 bricks I only lay half bricks on the exterior side....leaving a vent 4 1/2" to 5" wide and about 8" long in the centre top of my 1 and a half brick arch (I hope that makes sense).....I then use a double lined s/s insulated chimney. It is a good idea to buy a flange for fixing it to the bricks.
The vent normally needs to be 5" in diameter......your build may not have the depth for a 1 1/2 brick entrance, so you may have to use a lintel somewhere inside of the external arch .
I've never fitted a flue liner inside of a chimney, but if I did I would make sure there was enough room for a 5"....or 6" solid galvanised steel liner. You can then attach a cowl to this....if wanted. I would fill any void between liner and stack with either (the correct) insulating blanket...i.e..not normal rockwool....or loose vermiculite.
Even though all builds end up similar, the build process sometimes differ greatly in design. I hope that is some use to you.....and hope you get a bit more feedback on your question.
Regards....

Hi Terry, thanks for the response, I understand what you mean about the chimney. My build was going to be setup like this: (please excuse the horribly crap photo, I just knocked it up now and don't want to waste time when I've only got till lunchtime till the predicted deluge starts again!) Also, here is a photo of yesterdays progress - built up the corner of the side walls to their final course (yet to fill in the rest of the bricks on that course), cut all the bricks needed for the firebrick arch which I also completed, and cut the bricks ready for the red brick arch (which will be the same size as the red arch below for the log store). www.brickovenbuild.com/images/links/2012/brickwork/2012-06-05 08.56.37.jpg[/img] Hoping this morning I can get the red brick arch done and finish the last course of bricks on the left hand side.

Rain stopped play this afternoon but managed to get the front arch and base of the chimney done. Side wall that's visible is now up to final height. Side wall next to the fence is still 4 or 5 courses below final height. Rear is final height except the triangle needed to take it up to the pitched roof.

You seem to have introduced another arch in between the internal arch and the oven entrance arch.....nothing wrong with that. I haven't seen any one build the same......
Once the oven is fully fired the initial smoke and then the spent fumes will be drawn to the vent anyway. Looking at your diagram it will all fall into place.
I quite like the catalever affect to the entrance.

lovely work, I also got stopped by the rain Got to say I do like the arches, the view from the front looks cool with each arch just a little smaller than the last, pretty and your paint diagram explains the design which looks sound. lets just hope the rain stops some time soon :/

Ask and you shall receive... Gazebo down, garden looking like a pikey's and working on the chimney: and again: Jagged (un-even) bricks will be cut smooth later: View to show the vermicrete and back wall: 2inch thick piece of oak for the door (the full story of this will be revealed when I have more time): www.brickovenbuild.com/images/links/2012/roof/2012-07-26 16.53.49.jpg[/img] timber framing for the roof with fire starting (I love the lighting on this pic but it was on my camera phone with no instagram!) Also note the bricks have been cut, although two on the left need to be mortared back in place: Felt and batons in place: First sets of slate tiles: Most of one side done: Close up: Still to do: - Finish roofing near-side
- Start and finish far side of roof
- Cap with slate ridge tiles
- Lead work
- Extend chimney by 1-2 courses
- Top with concrete paving slab to mount chimney pot
- Polished concrete entrance
- Guttering (leading to a water butt round back)
There has been a dent put in my hopes of slating the whole floor area, got a quote from Marshalls via Jewsons for some 600x600 natural slate paving slabs, of which I need ~75 - £1600

I have absolutely no idea why, but I didn't put in a DPC on my outer brick work (despite putting one on my blockwork) and now I'm paying the price sadly. The brickwork around the countertop, especially at the back has been wet for 1-2 months now and is turning ever so slightly green with algae. Suggestions? Does the damp proof injection stuff really work? something like this: www.ebay.co.uk/itm/DAMP-PROOFING-INJECTION-CREAM-400ml-CARTRIDGE-EASY-DIY-USE-PROFESSIONAL-/320772434508#vi-contentThe main oven doesn't have any damp, not too sure why not, maybe it's because it has a roof - keeping a lot of rain off and the fact I don't have the countertop in place yet meaning rain can fill the void between the brickwork/blockwork of the countertop wall. I've never seen it pooled but I can imagine it will do. Thoughts please?

Hi Duncan
So glad you asked your question as I just realised I missed a whole series of pics on your roof stage........absolutely tip top...brilliant.
As many people know I go well overboard with dpc and put it in everywhere. Saying that the dpc on the brickwork should only stop rising damp and I have a feeling that pooling of water...." The brickwork around the countertop, especially at the back has been wet for 1-2 months now and is turning ever so slightly green with algae."... .........is probably coming from above and not below. You say you,ve never seen water pooling, but you may have to don your rubbers (outdoor wet weather gear...I mean) and try to see if water is somehow creeping down and entering the arch. It could simply be driving rain into the arch which could be cured easily enough with cover, but it could also be other things. The chimney area will always be a favourite spot for the rain to enter and find it's way inside the stack......have you put flashing at slate level?.....is it correctly fitted?.......it also may be that rain is simply being drawn in by capillary action at the top of the arch area, in which case a "drip" could be cut into the underside of the external arch with a 4" angle grinder.
Damp-proof injection works really well to stop rising damp and all the gear can be hired out from hire shops quite cheaply. I could be wrong but as I said I don't think it's from rising damp.
I think you have my e-mail address but not my phone number. I'll pop it in a PM to you in case you want to ask anything in person.
Terry
