Caldera cone metal

Kevin,

Thanks for the comments. I used a folded joint. I did the layout using a homemade scribe.

I am using a three cup aluminum coffee pot, which is a heavy for one, but fine for two. Impressive how well it works.

For one person, I think I will use a sierra cup so the stand can be a cylinder instead of a cone.

"I think I will use a sierra cup"

Most Sierra cups are made out of stainless or else titanium. You could try a Cascade cup, but I have never seen them in titanium.

Bob — I found a 750 ml Ti by Vargo. I could probably fry food in one this large. But it is too large for one. Evernew makes one, I think it is around 500 ml. Snowpeak has an aluminum one, but only 11oz (sorry about the mixed units). Anyway, too many choices and I was trying to hold to my gear moratorium.

The cone is a clever idea, but the sierra cup is, what, the dual?

"Vargo"

Wow, 750ml is large for a Sierra cup, but 4.5 ounces of titanium seems like a lot.

Sierra cups have about a gazillion uses. Soup pot, beverage mug, poor mirror, noisemaker for scaring off the bear or for calling folks to dinner, food portion scoop, etc.

I'm not positive if that Vargo cup is deep enough to be efficient on a Caldera. That's why I thought of the Cascade cup shape.

I've got an Alpkit MyTiMug, which I recall was very similar to a Vargo mug. Not sure if this can be the same as is being discussed here, given the comments about frying and being shallow.

Anyway, here's a pretty picture of the MyTiMug setup, with cosy and pot…

Crest with a split windshield. To all sides, the air supply holes are provided in the form of scales. Occurs simultaneously with the upward rotation of the secondary air supply and air supply by following this one. Around the corner at the bottom of the pot and goes to clash with the blue flame radiates. In this context, the secondary air supply causes the wall of the pot to the fire force vector. Would compensate for the oxygen component is also lacking.
Split crest. It is the exhaust area and earn great benefits, also acceptable to the diameter pot ambiguity. Thin metal plate is also spring-back capabilit

The carbon felt, which floated about 10mm from the floor. I made ​​a wire round the legs. To fit in the direction of evaporation is theoretically justified in burning part of the vertical sides.

Below, which adopted the theory of the bulbous bow, and two cases following description of the air supply. Born to the side effects of hot gas pushes the pot.

I like the scales and the variable width top with the tabs. I have made a few of these stoves, and the two challenges I have had is pot size (or opening size depending on how you look at it) and getting the right venting. Looks like your design solves both.
