In my recent article inward Seattle Backpackers Magazine (Aug 2, 2011 edition), I mentioned what my preference is inward price of a windscreen for an upright canister stove (well, at to the lowest degree for trips where weight isn't super critical). Something similar the below (keep reading if this looks also heavy; to a greater extent than ideas follow):
This is a self standing windscreen made past times Olicamp.
I hash out my preferred windscreen ready inward my article, as well as I'll become into some to a greater extent than item after on inward this spider web log post, but for directly I'd similar to hash out some of the alternatives that are out there. Before yous expect at these alternative windscreens, yous should carefully read my article and all of the security warnings in the article. Using a windscreen amongst a canister stove tin live real dangerous. Make certain that yous monitor the temperature of the canister ofttimes amongst your hand. If the canister feels hot, it is hot: Take immediate steps to cool the canister. DO NOT EVER LET THE GAS CANISTER OF YOUR STOVE GET HOT*.
That said, let's expect at some of the options out in that location for windscreens for an upright canister stove:
One peculiarly ingenious lite weight catch is Jim Wood's Kite Screen.
Another pick is build your radiations shield such that it has a lip unopen to the edge, similar so:
You tin as well as therefore purpose that lip to seat a windscreen inward house similar so:
Advantages:
Another pick is to accept a titanium bowl as well as cutting slots as well as holes inward the bottom of the bowl such that the burner as well as pot supports protrude through the bottom of the bowl.

I think the bowl catch has a lot of merit. Of class yous guide hold to sacrifice a titanium bowl, as well as it takes a chip of science to brand cuts that don't expect actually amateurish. The bowl inward the photograph was made past times Denis Hazelwood.
Finally, there's ever my preference:
This self standing windscreen consists of a serial of strong aluminum plates amongst wire rods that human activeness every bit hinges. This type of windscreen has several advantages:
1. It's self standing.
2. It's heavy plenty that the slightest breeze doesn't knock it over
3. It's tall plenty that it tin handgrip larger canisters as well as larger stoves. The canister inward the photograph is a 220g Snow Peak canister, as well as the stove is an MSR Superfly, a relatively tall stove.
4. It's real fast to ready (seconds)
5. The rods that human activeness every bit hinges tin live pushed into the solid soil to assist secure the windscreen.
BUT this type has a meaning disadvantage: it's heavy, weighing inward at 201g (7 ounces) which is virtually the weight of a 110g sized fuel canister (when full)!
For a lighter windscreen that industrial plant along the same lines, exactly supersede the higher upwardly windscreen amongst a windscreen made from multiple sheets of delineate of piece of occupation solid aluminum foil, folded at the edges such that the windscreen stays together, similar this:
The higher upwardly windscreen is significantly lighter, but far to a greater extent than dependent plain to beingness knocked unopen to or blown over past times wind. You'll in all probability remove to twosome the windscreen amongst rocks as well as such. The higher upwardly windscreen is also significantly less durable. But it does work.
So there's a real brief survey of some of mutual windscreen laid ups that I've seen for upright canister stoves
1. Self Standing
2. The Kite Screen
3. Windscreen mounted on radiations shield
4. Windscreen made out of a bowl or similar item
For whatsoever of the mutual windscreen laid ups, your imagination is the exclusively confine to the types of materials that yous mightiness use. Items such every bit pie tins, 36 ga. aluminum tooling fool, baking pans, catering dish lids, titanium bowls, delineate of piece of occupation solid aluminum foil, roof flashing, etc. are all fair game. Just remember: DO NOT EVER LET THE GAS CANISTER OF YOUR STOVE GET HOT*.
With that inward mind, leave of absence in that location as well as purpose your stove for what it is intended for: Good eats!!
HJ
*Letting the canister larn some oestrus inward mutual coldness conditions isn't a bad idea; it volition ameliorate performance. You withal remove to monitor the canister's temperature fifty-fifty inward mutual coldness weather. Even when it's mutual coldness out, that canister must never live allowed to larn therefore hot that yous can't comfortably touching on it amongst your bare hand. I'm talking virtually "normal" hands here. Be careful if your hands are actually cold. Really mutual coldness hands may non give yous plenty sensation to state how hot that canister actually is. Let your mitt balance on the canister a while. If the canister is actually hot, you'll know it before long enough! My betoken is that a quick touching on amongst mutual coldness hands may non live enough. Check the canister.
I hash out my preferred windscreen ready inward my article, as well as I'll become into some to a greater extent than item after on inward this spider web log post, but for directly I'd similar to hash out some of the alternatives that are out there.

One peculiarly ingenious lite weight catch is Jim Wood's Kite Screen.

The kite covert has an splendid reputation as well as is definitely a workable solution to the air current challenge. For me personally, the kite covert is a chip to a greater extent than ready than I similar to mess with, but many people actually similar it. By the way, if yous haven't checked out Jim's site, it's worth a look. Lot's of valuable information. Recommended.Another pick is build your radiations shield such that it has a lip unopen to the edge, similar so:
You tin as well as therefore purpose that lip to seat a windscreen inward house similar so:
- The canister is fully vented making it real unlikely that you'll overheat the canister.
- Since the windscreen doesn't remove to accomplish all the way to the ground, a shorter windscreen tin live used.
- It's a lilliputian difficult to secure the windscreen on travel past times of the radiations shield. Wind tends to knock the windscreen around. However, I've seen lots of examples of clever clips as well as other agency to secure the windscreen inward place. This is definitely something worth experimenting with.
- The lip on the radiations shield tends to larn bent upwardly when inward my pack. Influenza A virus subtype H5N1 completely apartment radiations shield is easier to pack.
- Because in that location is such a tight mating of the windscreen as well as radiations shield, it's going to larn actually hot within the windscreen. Plastic or other sensitive parts similar piezoelectric ignition systems could larn damaged.
- Because the radiations shield needs to securely back upwardly the windscreen, you'll remove to purpose a lilliputian chip heavier textile for the radiations shield than yous otherwise would.
- Since the valve command is inside the windscreen, yous guide hold to elevator or opened upwardly the windscreen to suit the flame. If you're exactly boiling water, who cares? Just plow the stove on as well as allow the danged affair boil. But if you're simmering, yous may remove to suit the flame. Influenza A virus subtype H5N1 huge deal? No. Inconvenient? Yes.
Another pick is to accept a titanium bowl as well as cutting slots as well as holes inward the bottom of the bowl such that the burner as well as pot supports protrude through the bottom of the bowl.

With a pot inward place:I think the bowl catch has a lot of merit. Of class yous guide hold to sacrifice a titanium bowl, as well as it takes a chip of science to brand cuts that don't expect actually amateurish. The bowl inward the photograph was made past times Denis Hazelwood.
