I decided to build a small oven in a tight nook located just outside of the kitchen as my current concrete patio & planned WFO build has been put on hold for now.
I plan on pouring a smallish 48" round hearth over sonotube columns. I do not wish to break the tiles to expose the concrete slab underneath, as some day this oven may have to be removed from this location, thus the reason for going with concrete legs. There will also be a layer of felt paper between the bottoms of each column and the tiles underneath to prevent bonding.
However, I will drive 1/2" pins into the tiles and down into the slab for each tube column to prevent shifting in case of an earthquake.
I might also cut some construction joints in the slab at grout lines and regrout.
The question I have is whether to go with 3 tubes or 4 tubes. Each tube will be about 30" tall. Four columns are definitely more secure with almost no chance of a tip over, plus the weight will be distributed over a wider area in that corner of the nook.
But I prefer the look and the simplicity of using just three columns. My only concern is a tip over as the legs will not be truely anchored to the floor, just pinned. But with each 8" tube just 30" tall this may not be a problem. I don't know. I can spread the legs wider apart from one another, bringing them even closer to the round perimeter edge.
The sonotubes pictured below are not cut down to length so they look rather long, skinny, and unstable, holding up the 48" round plywood which I will use as form. The wine bottles indicate oven opening.
Which do you think I should go with?
