    My Coleman Naptha 1-burner stove was delivered today.
    With the pump, the tank is 15 cm diameter and 14 cm tall.
    Call it 15 cm tall. Empty, weighs 900 g.
    Need fresh fuel but guessing maybe 500ml capacity. Listed @ 9,500 btu.

    Which brands of small stoves have effective wind screens?
    My intention is to look at some that are recommended then try to build one from riveted aluminum sheet.
    I can't hardly imagine a day out here that is not windy.

    I have a 1-burner butane cartridge stove with a poor wind screen.
    The vaporizing fuel cools so fast that boiling water takes an eternity.

    Check out the design of the brass Primus stoves. They did not change them for the duration of the manufacture, so what, 60 years?

    Is it the Coleman 1 burner dual fuel stove?

    If yes, I imagine a circular ‘tube’ or cylinder with cut outs for the adjusting knobs, small air holes should be ok?
    Diameter just larger than the fuel tank, height just above the pot holders.

    Will function as a pot stand too. Two parts, hinge, locking something on other side.
    Lower edge scalloped out, upper edge too.

    Folding aluminium type thing? I have a Fire Maple for my Svea123, and a larger Gelert. Both unfold and the hinge pins are pushed into the ground. Highly effective.

    I really do like that folding sheet metal wind shield. But once above the ranch lands in the valley bottom,
    we don't have any "ground" that you can push a pin into. It's all rocks, big and little.

    But Nice65, you do make me think that whatever I can do, it has to be free-standing.
    Then I have to think of the wind load maybe pushing the whole thing over.
    "Sod-flaps" that I can put rocks on for ballast?

    The holes in the shield dissipate the wind force, it will not get pushed over.
    You have not googled Primus windshield.
    Think a two part perforated tube. Hinge pin is removable. Nice 65’s idea with it being pushable into ground is excellent. Your idea with a bottom, pebble keeping flange too.

    Are you going to carry it?

    No carry. Not much better than tail-gate food/drink prep.
    I'm out a lot at -5C to +5C these days and the butane/propane stoves are too cold to run like I expect.
    They stay in the house for the power failures.

    I have a Thermos and an Aladdin flask but that's of little use if we are a group of 4.

    I carry a 5 gal water can. Then I might want lots of warm and hot water in a hurry.
    There's always somebody in a mess that wants to clean up.
    Not too funny to listen to the ice chunks banging around in the water can.

    Besides a Coleman green box, I figured that a 1-burner running on Coleman fuel will round out the kitchen kit.

    Ok, then you are not aiming for ultra portability.
    You should be able to find an aluminium box you can adopt.

    As a temporary ( lasts a few days) windshield you can use Alu kitchrn foil. Scrunch it into a suitably high wall around the cooker.

    I looked at the Primus clamshell = very good design. If I could swivel that around. . . . might be OK.
    I can putz around with some hard card stock and a glue gun
    to build a proto before going to the Al sheet & rivets.

    I have to be able to get at both the pump and the flame throttle in the first couple of minutes to get it lit.
    Typical Coleman. After that, you can't kick it to death, same as the green box.
    The two controls are maybe 120 degrees apart on the tank so I need a lot of access.

    Snow or no snow tomorrow, I'll hope to buy some fuel, check for leaks and get it going.
    I want to weigh it and estimate fuel consumption per hour and boiling times.
    I can use the smoker BBQ for a wind break.

    I have now seen several swedish outdoor cookery/ travel programmes, and they all used Aluminium foil, semi scrunched up, around the various heat sources.

    I have bought two of the generic folding wind-shields and attached them together so they can go all the way round my stove with ease. I don't rely on pushing the pins into the ground as they are too thin and flimsy. Instead, I drilled a small hole in the bottom of each plate. I can use some standard tent-pegs wherever needed, pushed in at an angle, to secure the shield to the ground. On hard ground, like you are talking about, I put the tent-pegs through these holes from the inside, so that the tent-pegs are sticking out horizontally on the ground like the spokes of a wheel with the hook against the inside of the shield. I then pile stones or whatever around the outside on the tent pegs and that holds the shield in place, even on a windy day. A couple handfuls of gravel/small stones on the inside also helps. Don't know if I've explained that clearly or if it's any help.

    Mike313: Thanks. I understand what you did. Not hard to imagine at all. Well-written.
    The accordion-folder style of linked plates is the way I will go. Two of them is a good point.
    I'll consider a canvas skirt that I could pile stones on for stability.

    Just about the best windscreen I've ever had on a stove came with my msr dragonfly.
    Is just really heavy gauge aluminium foil. I put a giant paper clip on it to adjust the size and it's lasted for years and years
    I use it with a fancy feest style meth stove too

    I reckon those disposable foil oven trays would be pretty close to the same stuff and all you need is a pair of scissors

    Cut holes there you want them and maybe ad some skrews as legs. Maybe cut a whole section för easy handling.
    Not lightweight but it can take a beating and in a pinch it also works with wood or coal.

    I just bought a humungous 'disposable Turkey Cooking Tray' (the tray is disposable, not the turkey, - but the Turkey will be disposed of later)
    I think the cost was about £1 - £1.50 or so.

    Cut off all of the 'shape and edging' to be left with a big rectangle, folded the edges over and over to make a 'stiff border' until it was the correct size to go around my stove (about 3/4 of the way around to leave access to the knobs and allow air to get in).
    It stands up quite rigidly (but would need some fixing in a strong wind) but folds up into a very small, light weight square - it weighs about 20 grams

    My msr screen doesn't even have the edges folded over and I do not take good care of it lol
    Gets folded in the same places often, rammed into any space it will fit, and its always one of the items i pack in places that are likely to get knocked.

    Having it adjustable in size mostly stops it blowing away but a few times I've used spare tent pegs hooked over the top to keep in place.
    I might take a pic of it. Honestly I'm astonished at the abuse that bit of aluminium foil takes

    I've got the better part of a 50' roll of 6" aluminum sheet which I can pop-rivet lengths to make any size pieces.
    48" squares of box card paper stock as well for a glue-up prototype design.
    I can't get big Al trays here in the village. Smaller roasting pans but no big stuff.

    Our Postal Service is phuqued up with massive rotating strikes right now with no end in sight.
    Anything I'd buy on line could take 6 months to cross the country.

    I folded my edges over to make it more rigid.
    About 1/2" folded over twice gives a 1/2" 'border' with 4 times thickness and makes it nice and 'stiff' but still bendable.

    Yours will be stronger for sure mate. I'm just constantly astonished that mine has lasted so long

    I have had my MSR foil windshield for over 20 years and it is still going strong. a couple of small nicks in it, the heavy duty foil they use works brilliantly. Another cheep alternative as many have said it the heavy duty foil you get with some disposable tins and trays they work too.
