> I do have a different sort of leg which does not have the centre support. It works, but the springiness seems a bit chancy in comparison. The wobble is definitely obvious.
This might be a little difficult to describe. I am thinking of the cheap type of photographic tripod that has the center supports to stiffen light legs. Well, very expensive video tripods have these supports as well.
Anyway, there are the three legs, of course, and these make it possible to always have good contact with no leg/earth wobble/totter.
About 2/3 way up the leg are cross members to connect the three legs to a central support. These cross members are hinged and fold out of the way when the tripod is collapsed. The central support could be your burner tube.
I suppose little rods could run from each leg to the burner tube/housing. I don't think a hinged rod that remains in place, as with the photo tripod, is practical. The rod may be hinged on one end or come free altogether. On the burner end, there could be a little dimple or receiver for the end of the rod/wire. Securing the leg end of the rod is an exercise. Threaded sleeve magically attached to the side of each burner leg?
I think just running the rod from tripod leg to leg without meeting in the center would add stiffness. This might be easier to implement.
Running around the perimeter allows at least two methods of implementing the idea. Three rods could be used to run between the legs without heading to the center. I wouldn't position them 2/3 up. Maybe halfway up.
The rod could slide through an opening in one leg and into a receiver on the adjacent leg. The opening in the first leg could be a threaded sleeve (attached with any remaining magic) that the rod, threaded at the end, could be screwed into. Attaching the threaded sleeve to you stove leg probably isn't practical. Tapping the leg itself probably wouldn't be enough simpler.
What might work is to make a wire loop pre-bent for the triangular shape of the tripod. The wire could be thin. It just needs to be strong enough to put tension on the legs. Each stove leg could have a little groove for the wire to seat in. The two ends of the wire could be joined and tightened by a couple different ways. Some kind of tiny turnbuckle type arrangement. Whatever.
[the whatever would need to be something that could be finger tightened easily enough to properly tension the hoop. for this reason i don't think a typical turnbuckle that requires a wrench is practical. the user doesn't need a little tool to deal with. I can't imagine a micro turnbuckle has a built-in lever..? maybe little turnbuckles with flattened edges exist. the turnbuckle equivalent to a wing nut.]
If it adds enough stiffness and allows 3 points of contact to be viable, it might be worth the trouble. If the burner housing can be smaller because it doesn't need extend to the ground, that weight saved would offset the connector rods or wire.
It does add to the assembly for the user. Increased fiddle factor. Most stoves just fold open... The hoop wouldn't always need to be used. It could be lost or not used when it should be. It creates a bit of room for user misdecision. Error. Pegs a user must place to secure a stove are also a thing they could lose or fail to use. I guess it depends on the user and the number of warning labels on the packaging :^)
I don't think I would worry with Deep Thought. The answer is 42. If the tripod legs are wobbly, I wouldn't give up on the benefits of tripod design. I would consider stiffening them. If the legs flex in and out, use a wire hoop to pre-flex them in and prevent the out...
