Hi all
cobblerdaves build-last.jpg

state of play thus far still suffering from intermittent damp. As you can see from the photos the ugly piece of tin and the even uglier piece of blue tarp have solved the problem but a prettier more perminent solution must be found.
Problem stems from the hearth continuing to the edge of the slab and the entrance is 1/2 brick back. Any rain doesnt flow into the oven but is soaked up by the brick and of course is wicked in by the hearth insulatution.
I concidered cutting the brick back to the entrance level but its good to have one level right back into the oven. That left me with the option of rebuilding the entrance itself. Wow that would involve knocking down quite a lot a major job at this stage. And it would give me quite a tunnel to work the oven through. I decided ... Do noting rash... wait...Watch the forum and do something in the dry months of winter.
I finally came across few comments on a few thread on entrance depth and finally one with some measurement... great mine is'nt that bad so the plan is to build an extention to the entrance...Thanks Oscar... and its to be a arch

Regards Dave

Great job on the arch Dave I'm glad my build helped you decide on the arch and hopefully your rain issues are now a thing of the past.

Hi Dave,

Just curious, how is the hebel as an insulator? The reason I ask is that I am having my house rebuild and it's being clad in Hebel, so plenty of offcuts around which I may be able to use.

Himzo.

Dear Himzo
How have I found Hebel as a insulator.....well its worked for me... but the tried and proven is the old pealite it seems.
Didn't work for me at the time the only supply of pearlite i could find was expensive small bags at Bunnings /garden supplies. I have since found 100 ltr bags are available at hydroponics suppliers at about $35 a bag.( A ltr is aprox 10cm2 by the way)
At the time funds were low and I had already heard it was a good (affordable) method of hearth insulation in other oven types so I went agaisnt the tried and proven in the instructions.... its worked for me the ovens not crumbled into the insulation layer after 20 good firings.
If its not that eco stuff , the stuff with the strofoam layer... plastic you don't want that and its what you have ......well why not.. its up to you what you decied but there are a lot of oven builders in SA put a thread out asking on insulation and your sure to get some great local knowledge

hope this helps
regards

Hi All
Progress to date on sealing this oven Great... and is successfull. Oven remins dry even though we have had a least one good shower of rain a week.
Arch complete so the hearth now has overhead cover from the rain and any drips from the edge fall outside the oven. The entrance is deaper than what you would normally find but I have a rectangle dome entrance and tending the oven is no problem. I do have the advantage of an extra large entrance which let you lite an ambient fire to sit in front of once the eatings over and just talk and watch the flames... priceless...
Brickwork has been cleaned down with vinegar and finally pressure sprayed to remove the last of the lime scum, Then it has been given 2 coats of "Bondall"
sealer to prevent the old bricks from soaking up any moisture. This has darkened the brick slightly not in a bad way...best way to put it ..inhanced the colour.
Yes I have thought of inclosing the whole oven at times ..but really I like the dome look. As long as you take measure such as sealing the dome render with a sealer and the entrance is covered you shouldn't have any problems.
The main difference is that I used old bricks which were not as water resistant as you would hope. The bondall sealer has solved that and I like the look that the mix of different colours and texture has given the oven. By the way some of the bricks in sections come from an old church and 1 I had for years as a door stop came from an old pub.
