I've been working on this for a while and am happy to finally share it with you all. Here's my new cook stove, built around a ceramic fiber riserless core.

Nice! IIRC you hae a Testo. How's the emissions when compared to the standard Batch Box (with p-channel)?

It tests better than most, and on par with the best I've seen. It has a longer period of very low CO, and tends to be more stable. That said, a perfect batch can achieve lower excess O2 and probably slightly edge this out in efficiency. That remains to be seen though, since I have not had a chance to test one with a full thermal mass yet. This one will give me that opportunity, but it hasn't been cold enough outside to do any testing. Warm and windy and wet still.

If they're comparable under ideal circumstances, then I surmise they'll be virtually identical under normal operation.

Matt, when you use those ceramic/glass tops. I wonder, do these shed a lot of heat? Could you stir fry on one?

And what about weight bearing capacity? Would you use a large pot full of water, as for canning? How wide a perimeter is supporting the top? I can on mine at home and wonder if I'll collapse it one day.

Thanks everyone. Those tops will take an enormous load without breaking, and yes Max, they are capable of cooking at incredibly high heat. Mine is way hotter than the electric stove ever was. I use a cast iron griddle on there and it sears steaks like it's the sun. As for the load, I use a giant All-American canner and have loaded these tops down with multiple pots and never had an issue. I'd be truly surprised if one of these broke from a load on top. That said, keep in mind the serpentine path under the top does provide support at points, so the top is not completely suspended.

I just got a lovely email I would like to share here. This is the text from a very nice customer who has completed his build. It's built using the Tiny Cook Stove Plans with modifications to the body to allow him to build this into his existing fireplace. I think it's a lovely solution and the side bell could be a roasting oven if one desired. This made my whole month, and I just had to share! "Last night I finally got a fire in it and your design is fantastic. Only took about 2 fires to figure out the draw and how not to smoke the place out on start up. Really keeps the place warm using very little wood. When I move back to the country, I'm going to build this style again with the oven. Thanks again Matt. Really love your design. " "Your design was very easy to build. The hard part was deciding what to put around it. The black front is actually the drawer from the stove. In fact the core is encased with the donor stove parts. The door was made with the stainless steel parts of the donor stove. And I got the stove for free off of craigslist. The donor stove oven box (which could be used as the core surround), came wrapped in a ceramic fiber blanket which I used as gasket material and it provides an excellent seal around the top and wherever else one might need it. I would encourage others to follow your plans for the door because it's a great place to start and saves a great deal of time. I got the door window glass off of eBay and the seller will cut it to whatever size you want. Cost about $22. The latch idea is the bomb. This was the first time I ever worked with laying bricks and would encourage others to lay it out dry first. Youtube how to cut bricks with a hammer and big chisel. It's really fast and easy to do. I got the chisel from harbor freight for about $10. As you can probably tell, I didn't cut the glass top though I could have. It just seemed to work better for me to leave it uncut for this application. Yes! I'm thrilled with the finished product and it looks and works great. Thanks again Matt and if there is anything I can do to help other folks, just let me know"
