upsizing pot capacity with a Ti Tri Classic

The only way I see you using that cone with a taller pot would be-

A) using a much lower profile alchy burner ~(tea light , etc) or burning esbit with no platform.

B) drilling holes at the proper height to use stakes as pot supports for the taller pot ala the sidewider cones.

Thanks Jimmer — That's what I thought. Maybe I will get both pots and try out your idea. I can always use the big pot in wood burning mode, eh?

There is another way.
get a silicone egg mold.
Slide it up to the base of the handles on the 850ml pot and that should be close to deph of the 550ml pot.
Something like this (imagining that the plastic caddy is the 850ml pot…) :

Hmm, I happen to have a few of those in my kitchen right now. Thanks Franco, will try this as well.

If the pot will sit deep enough in the cone it might work with a cat can stove. I use my sidewinder without the stakes with a cat food can. My pot will rest on top of the cat food can and still be supported by the cone. It saves me weight by leaving the heavyer caldura stove and stakes at home. With my pot sitting deeper in the cone, it better conducts the heat and I can use a little less fuel to reach a boil.

i wonder if it would help to switch out the standard caldera burner for the starlyte burner. Ask Traildesigns.

Good observation. My .9l sidewinder uses skewers with the standard burner, does not with the starlyte.
