great little stove. good luck with the pot stand. i think some of the flame jumping is because the holes dont go all the way around. if yours do then i'm wrong but i havent seen one that does and i think its the reason.
You may very well be correct. I only have 1 larger hole for air intake. I don't have an original FF to work off of, so I actually didn't know they had holes all the way around! LMAO. I may add more holes as an improvement in my next prototype. It depends on certain parameters, as I have less material to work with in this miniaturized design. Thanks for the very useful info! Peace.
they dont have holes all the way around. i havent seen one yet that does. sorry thats what i was trying to say. if you do it with hte band like that its hard to have the holes evenly spaced all the way around. i think it causes the air flow into the stove to be one sided which causes it to not have and even burn across the surface of the flame. making hte flame look like its jumping. or atleast thats what i think.
Gotcha. I see what you are saying. If you COULD space them evenly, it should solve the air flow issue. The conundrum, as you said, is in accomplishing said design within the parameters of how the stove is currently configured. In my current proto, I only utilize 1 large hole, which can theoretically cause the flow problem you stated. My problem is in miniaturization. I just have to be tighter on my measurement tolerances. Thanks for the clarification. Peace.
The updraft pressure becomes stronger when it's hotter inside the stove. I believe this greater pressure is what overcomes the jump potential inherent in the stove at cooler temperatures. You may be right that the unevenly distributed holes are the imbalance that creates the instability in the first place. I wonder if this was corrected in later versions and found to be true?
It seems to me that you could anchor a screw type hose clamp. They type where half of it has a slotted end, and the other half is solid band.
With that, your adjustment screw would come anchored to the solid end and move out as it is adjusted to open the air intake.
The middle of the slotted part could easily be anchored to the side of the can, with the end of the slotted part sticking out some for the screw adjuster to ride on.
Makes sense to me. That type of mechanism should work, however, there may be a new problem that it may represent for me. My main ideal is to lighten and miniaturize the design. If I could find a hose clamp of that variety made from aluminum, that may be perfect. Unfortunately, no such animal is sold in the hardware shops in my area. Definitely something to research. Thanks for the great idea! Peace.
Thank you, Bill. I hope to make a how-to once I have the pot stand figured out. I will say this, it is a complex stove to make, as DIY stoves go. Many parts. Peace.
Thanks for the mention! Outsanding design. I like this version. Downsizing is a great idea. As for a potstand I and Irrationalsolutions have discussed using hardware cloth. Making all the bends for the potstands like the original is tough plus making each one the same is even tougher. Great job once again.
Thank you for the input! I couldn't have made this as quickly without you and Irrationalsolutions doing most of the tough reverse engineering. I also considered the hardware cloth, but I am going to try to make a stand similar to what the original manufacturer uses. You are very correct in that it will be difficult, but this stove is a bit of a project as it is anyway, so I figure I will try at least once. Anyway, I will keep you updated. Peace.
how to polish this kind of material if your not painting it?... this is aluminum right?..

Self correction, ALL. I made a mistake in the can sizes. It's a 5.5 oz. juice can or a 8.4 oz. Red Bull can. My bad. Peace.

Yup. In proto #5, I have the holes going all the way around, and it makes a difference. Thanks for the comment, Tim! Peace.

Ah, I get it. The pressure oscillates because of uneven heating in the chamber due to uneven air distribution. Irrationalsolutions hit a bullseye.

Does that make sense?
