Re: Oven in North Yorkshire UK
Hi mpjfitz
Thanks for the comments. The 6'' pipe draws smoke fine when the oven gets up to temp. I tend to build a big pile of wood inside the oven (nearly full) so I get quite a bit of smoke produced at the start before the chimney has warmed up. If I was less lazy and started with a small fire I think it would be OK. The front of the oven gets a bit black with soot (I noticed that Jamie Olivers did this on his TV show). When the oven is hot there is hardly any smoke anyway as the fire is burning so efficiently the chimney works better the hotter it gets.
The mortar was a ready mixed refractory cement that I purchased from Handsworth Refractories in Sheffield UK: Handsworth Refractories - Services
Not listed on the site, phone them and ask for it.
Its not cheap, about ?40 a tub (i think) and I ended up using 4 tubs but ist damn good stuff (i filled the gaps at the back of the angled blocks with it so used loads). They use it to glue fire bricks together in huge steel works crucibles, I asked if it would contract or crack on me and they said they used it to keep 1000 tonnes of molten steel in one place so NO there shouldn't be a problem. I have to say that nearly a year on its still going strong, small bits have cracked but its very simple to just push a bit more into the gap and then let it dry to cure.
I'm also posting some new images of my oven with the extended roof section now infront of the chimney (this needs pointing), it is working to keep the rain away from the oven enbtrance.
All the best
