I studied Graphic Design at art school. Then also studied ceramics part time when I became a teacher.
Barcelona is a wonderful, vibrant city. It's hard to believe Spain is having economic difficulties when you visit this great city.

Barcelona is on my buckle list. I can't remember what was your specialty in art school was. Mine was ceramics although I have not done any pottery work in decades. Maybe time to start again now that I am retired.

We visited many of Gaudi's buildings while in Barcellona earlier this year. The Sagrada Familia (cathedral) is the most magnificent building I've ever seen. Have been a Gaudi fan since Art school in the early 70's.
See my attached pics of his model catenary arches for the cathedral and an interior pic. It is like being in a rainforrest looking up at the canopy.

David,
I think that Gaudi was a little more into the "abstract" than your symmetrical arched "hex dome?" appears to be. I had guessed how you were applying the render. It only makes sense. And I had looked into ferrocrete a few years ago. I even looked at some of the boat builds that they do for college competitions. Again, that is a very cool project you have going on. Please keep up the posts and the pics.

Is the render being applied from the outside, with the person inside using something like a trowel as a backstop?

David,
Like Gulf, I some how missed this project of yours, keep sending updates. You go from having one of the smallest WFOs to the large and massive concrete structure, LOL.

Working with one on the inside and one on the outside it is going up pretty fast now

Up she goes. I've had a lot on my plate and this project has not been a top priority, but I try to fit in an hour or so here and here. Attaching the layers of chicken wire was way more time consuming than I thought. The stuff needs to be sewn together using fine tie wire and while it's relatively simple , takes a long time.
The cement render needs to be done fairly quickly though. Ferro cement boats have to be rendered in one go apparently. Working with one on the inside and one on the outside it is going up pretty fast now.Last edited by david s; 09-30-2015, 01:43 AM.

Re: pizza oven becomes a kiln
Having cut and welded the main members in position (see arc formation on wall from suspended rope to create required curve), I purchased some more steel bar, 6.5 mm this time, cheaper, easier to cut and bend. So far I've only spent around $200 on the steel, This is going to be a really cheap structure, seeing it's 3.3 m in diam. I think it will be quite economic.This was really good fun, working like a spider, (what great engineers they are). Estimating cutting , bending and welding in position with the final form in mind is a way I like to work. This was easier than it looks.
The next step will be to mesh the structure which will be the time consumer, cutting and tying layers together. (See test bit on one leg, last pic), using cement render 2.5:1 sand, cement, incl. AR glass and polypropelyne fibres.Last edited by david s; 06-20-2015, 12:39 AM.

Ferrocrete! That's going to be very nice, David. I hope that you will post pics during each stage of the build.

Re: pizza oven becomes a kiln
I need to have a weatherproof cover over the kiln and have come up with this Gaudi inspired solution, based on catenary arches. I plan to build a skeleton of 8 mm round steel bar covered in layers of chicken wire over which I will apply a cement render.Last edited by david s; 06-16-2015, 12:39 AM.
