What a brilliant build.....and thank-you for sharing your stage pics with us. I love the bricks you've used on the arch. They will definitely showcase your finished oven (it's sometimes a shame that people who come to your pizza evenings don't realise how much work has gone into the bits that they don't see)
When I've used a finish coat of K-Rend I have trowelled it on using a plasters trowel as even as I can get it by hand, then waited for it to crust up a little....perhaps an hour or so depending on the weather...then gone over the whole dome with a sponge. The sponge will take off any ridges left from the trowel and leave a nice even sandy finish.
Same as Terry with the light sponging for the finish coat... This wouldn't apply to you with your rendering skills, but I found that on the dome a small 'continental' ie rounded-point trowel worked best for me - easier to manage the small amounts applied at a time, and easier to use over the curved surface. Love the rain-shedding back corners!
I have recorded the cost for each item, I will post it as soon as I have it in a good format.
When I used the oven last Tuesday I took temperature reading around the oven both inside and out using an IR thermometer.
Hearth temperature just after I moved the fire 416.5℃ Temperature on the underneath of the hearth 30℃
Temperature inside the dome at the top 618℃ Temperature inside the dome on the side opposite to the fire 456℃ Temperature of the dome skin (Was in the shade but the sun had been on it a little earlier) 29℃
Inner arch 433℃
Top of the chimney pot 39℃
Hearth tiles in the entrance 125℃
I finished using the oven about 17:00 I took some more temperature readings using the thermometer on the oven door.
That evening 21:00 200℃ 23:30 175℃ 8℃ outside
Next day 08:00 125℃ 11℃ outside 23:00 75℃ 9℃ outside
Day after 08:00 70℃ 7℃ Outside 18:30 50℃ 13℃ Outside
That's not a bad price considering what you have achieved. I never kept a tally on the price of my oven as it could have been used as evidence for the other half to spend an equivalent amount on bags and shoes( yes she hoards) so mine cost £50 all in.....ahhhem
Just for info try and aim between 300 and 350 in the cooking area as this is what most Italians aim for in traditional ovens.
Very nice job and all round to yours for Pizza and beer then....
Price wise, you've done really well. I haven't bothered too much with the price because I bought the oven as a kit and deliberately chose bricks for the base which were of better quality than basic ones. Certainly, mine cost a lot more than that!
I love the look of the chimney it contrasts beautifully with the light colour of the K-rend.
We have the same Holly and David Jones cook book - I get the feeling that you are not especially impressed with the results - is that your overall feeling?
I thought I would post an update of how the oven is getting on after a few years of use.
First to the outside....
The dome has a few hairline cracks in it, the render is three layers thick so I don't think any water would have got in, but it is on the 'to do' list to re-render.
The tiles round the outside have suffered from the frost almost all of the outer tiles have cracked, I have the replacement tiles I just need some spare to fit them. This needs to be done prior to rendering.
And I need to do some pointing
I had a piece of the dome fall out the other day, it's a filler piece above the inner door on the inside. I have already started to clean the brickwork read to refit, I just need time to do it.
You've probably completed the floor by now but a good rule when laying tiles is to do all the complete tiles first, then cut the nadgery bits; it gives you something to work from. Looking good, keep the pics coming.
