I would have thought that a clikstand is bit too small to retain enough heat and fuel for a viable fire - there just wouldn't be enough energy retained in the fire bed to sustain good combustion.
I hadn't thought about the theory, just tried it out in practise, it was enough to get a good rolling boil with over half a litre of cold water in a fair breeze, I'm not sure how much difference that would make, I guess I ought to try it on a still day sometime.
I would also just about guarantee that if you did manage a decent fire in one, it would be pretty much destroyed - springy stainless that thin will deform badly and lose it's spring.
Yeah I'm a bit concerned about repeated use, I guess time will tell on that one.
Though keeping it to just boiling half a litre or so it's probably only at full temp for less than 5 minutes. Not sure how that would affect the tempering and springyness. Wish I had some way of measuring the temperature of the wood fire and the steel, as your point above may even be keeping it from getting much above the temperature it was designed to operate at.
I'll keep mine dong the job it was designed for (and which it does very well) and use the CD sized
nimblewill type firebox for little woodfires.
I just had a measure up and done a calculation of the Clikstands internal volume used as a wood burner, max is a little over 1/3rd of a litre, during my test burn I couldn't have used more than 0.25lr ( that's ignoring air gaps for now )
The Morrison's hob ( as used by Wayland ) must have roughly 100mm internal diameter 0.25 litre would be equivalent to a little over 3cm high worth of wood in the bottom of one of them ( Though as it's circular and you need to be either dropping wood down the top or putting it in a small side door it probably doesn't pack as well so real equivalent figure might be closer to 4-5cm high ) Has anybody measured the thickness of the walls of these?
From that link I guestimated the Nimblewill to have a internal volume of just under a litre.
Something else that might be making a difference here, when using the Nimblewill ( it doesn't have a bottom grate does it? ) or Wayland Hobo, when the wood or ember volume is low the air is being drawn in from the sides whereas with the Clikstand ( once it's going and the windshield is in place) it's being drawn from mainly underneath and stays that way till the end. It's possible this is making a difference in the ways which they burn small volumes.
Going back to your first point I was using very dry wood, maybe it wouldn't have worked so well if the wood had a higher water content.
Overall I must agree with you that if I was going for a few days in a wood I'd take a proper wood burner. The whole concept of burning wood in a Clikstand this way came about when I was trying to find a way to not have to carry extra meths in a bottle, alongside a full Trangia burner, just incase I wanted to stop out a day/night longer or had extra tea cravings and didn't want to use an open ground fire.
How well something works can be very subjective. This setup has passed my preliminary tests to my satifaction ( which I admit I didn't have high expectaions ) but in fact for that one test it was better than I expected, only repeated use under differing circumstance will give me a long term opinion and show up faults.
