Sidewinder rocket stove-- Walker variation

So back in 2019, I built this prototype rocket stove to heat water. I think it would work great to make maple syrup, but I digress. I didn't like the metal in the burn chamber in rocket stoves. The double rocket pizza oven burned out the secondary air feeds rather quickly. So I thought I would make a channel outside the chamber to do it. I used metal here on the prototype, but I've since built a batch burn RMH with just fire brick for the feed. Anyway I have a lot of pictures of it. First is the overall configuration and the next set are the measurements.
It burned really well and very hot. I will use the design for brewing beer, but I will insulate the sides much more as it gets extremely hot. My friend had a laser thermometer on the bricks in the fire chamber while it was in Holland and it was 458C over 900F two hours after it went out. This can easily be done by cutting the firebricks to make the two channels. Or in the midwest they make handy firebricks with three tube like holes through them. Makes it easier
Anyway, I meant to share this back then, but I've been super busy these last few years. Sorry about that. I hope this can be helpful to anyone wanting to make a sidewinder.
And Thank you for the Walker stove inspiration.

And here are some measurements for those interested. I made the burn chamber bigger.

It looks like you have put a lot of work into your version , I hope it performs as you would like.

That tank on top was sealed on top to create a water tank. The purpose was to make a smokeless hot tub heater. The problem was it didn't have enough height difference to thermal syphon well enough and it just threw out so much heat in all directions. It would really need to be in a water jacket to perform that well and be lower than the hot tub by more than 2 inches.
That being said, we all were really pleased by the amount of heat it threw out in all directions. Every test fire was a sweat fest. It will make a great masonry stove for a house and I hope a syrup maker after I cut the top off again and perhaps make the pipes a bit smaller. I'll make the syrup maker slightly different-- mostly more insulation. We hope to have it into my friend's house this winter, but it will be in January. At least it will heat through the coldest months over here. It is there waiting to be installed and the steel will be replaced with bricks and ceramics. I'll keep the steel body for the syrup making.
