Hello all,
I am currently prototyping a 15.2 cm diameter (6") DSR2 in my kitchen. It will primarily be a heat source, but if it can also be a cooktop and an oven, that would be a big plus.
I am working on the cheap with secondhand and salvaged brick and large sandstone? pieces from an old fireplace. To raise the firebox, I used the old fireplace stones to make a pedestal for the core, using two large blocks with slab pieces on top to make a platform. The core is currently dry stacked on the platform with heavy bricks for the firebox, superwool lining the riser, and insulating bricks making the upper shoebox. I have a 60x52x2.5 cm slab of refractory material, that I will cut to make the top of the firebox, and the spacers for the heat riser to keep the brick courses level. I need to figure out what to use as the roof to the core, as well as the roof for the stratification bell that I will build directly beside the core. The bell would go all the way to the floor, and would/could encapsulate the large mass of the pedestal. (~40kg of stone). The exit would be at the rear of the bell, at floor level, comprised of a tee with plug, and flue pipe going up through an existing chimney, as a liner.
The dry stack core that I built in my backyard burned very well, with no visible smoke at the top of the heat riser. I was also able to boil water during a very cold day, in a pyrex saucepan on top of the stove glass, but not really a rolling boil. I have clay to make slip for use as mortar between bricks, for easier disassembly in case my experiment is a failure, or if I need to re-engineer it. If it all works, then I will either cover the whole thing in cob, or rebuild it using refractory mortar.
I have salvaged the ceramic glass top and oven cavity from a discarded stove, and am hoping to use them. I hope to incorporate the oven cavity into the bell, and the glass as the roof over the top shoebox, to possibly cook on, or at least warm things. This would entail cutting the glass in half and using the two pieces lengthwise, to span the length of the core. It would also require a way to seal the seam between the two halves, and I would still need something for the roof of the bell. I am currently searching for a bigger piece of stove glass, but not many are made that could cover an 85x34 cm span. If I can incorporate the oven cavity, I would be looking for a way to regulate its temperature. This could be a fully adjustable bypass damper, or as simple as opening the oven door a bit, to let hot air out, as my idea is to only bake in it, when I need heat.
What would you use as a roof for your core and/or your bell, with the hopes to use part of it as a cooktop/warmer? And is there a sealant, or method of sealing the seam between two pieces of stove top, keeping in mind the temperatures encountered at the top of a DSR2 core? Would you encapsulate the large stones of the base, inside the bell?
I am open to pointers, advice, criticism, sarcasm, or just plain ridicule, but of the constructive type, please.
