2 Part Cone Windshield - Prototype

[Matt]

Made one of these before but I've never been happy with how they fasten together.

New idea trying some of those super strong 1mm thick earth Magnets

Happy with first test

[Bearbonesnorm]

Very neat. I'll have sheets of .3mm at the WRT.

Have you checked to see what the temp range of those magnets are? I'm sure it's 80 degrees which might be borderline if they're attached to the inside of the cone???

[Charliecres]

That looks great. Is it Ti or Ali?

Been after some suitable stuff to make one of these for ages. Any chance of selling/posting some of that .3mm sheet, Stu?

If you're not at the WRT then I can send you some, have a work out what you need and let me know.

[Charliecres]

Cool, thanks. Can't make WRT, I'm in Scotland.

[Matt]

Okay so it's a massive fail!

Currie level is too low, I now have non magnetic. Magnets

I managed to get some 0.2mm steel shim from RS through work. I downloaded the template from zen stoves.Pot from R and R backpacking and the lid from fourdog in america. Fits rather nicely in my tangle bag and more than big enough for little old me.

Is that the 400ml Evernew mug you are using ?

[jpw247]

Yes that's the one. Annoyingly it doesn't come with a lid though.

[Mart]

I went with the 550ml version for that very reason, to get a lid (ah simple pleasures)

That titanium foil link looks interesting. Anyone got any/can comment on how suitable it looks?

At 0.05mm it's pretty (very) thin so probably wouldn't support a pot if made into a cone. I've got a Ti windshield in the workshop in the same thickness and the greatest difficulty is preventing it from blowing away

[u02sgb]

Thanks Stu. I read you had some Alu foil that might be good for making a Flissure? Got any left?

I still need to print out a template to see what size I need but fancied trying to make a small one for my 450ml mug. I saw Iain's first attempt melted so want to make sure it's the right thickness. It's to go with my 8g stove.

I'm expecting some more to land next week. It's 0.3mm thick, won't burn but's still easy enough to work with ... give me a shout.

It's to go with my 8g stove.

Just remember the 8g is designed to work with the mug directly on top, so any cone only needs to act as a windshield rather than a combined shield / pot support.

Is that the same stuff I used?

Could you get away with thinner material for the 8g stove, as it doesn't put out quite so much flame as the one that burnt through my 0.15mm foil?

[Ian]

Also, I note the Titanium Goat foil is 0.005" (0.127mm) thick, so thicker than the eBay stuff. I'll order some and see what it's like. My 0.25mm alloy is looking a bit tatty anyway.

[Bearbonesnorm]

Is that the same stuff I used?

Don't know, did you get it from me? If you did it'll be either 0.2mm or 0.3mm ... I only ever have 0.2mm and 0.3mm but prefer the thicker of the two.

If all you require is a windshield, then the stuff from Ti Goat would be great.

[Ian]

Don't know, did you get it from me?

Wasn't it the other way around? (or at least I sent you details of what it was that Matt and I used...)

[Bearbonesnorm]

Ahh, I remember now ... yes, you did give me the details but no, this stuff's different. I think what you had was the same as used for making printing plates?

[Ian]

Yes, that's the stuff.

I've ordered my titanium goat foil, so we'll see what I can do with it later this month.

I was planning to run it with a small gap (0.5cm) would this work ok? I'm still getting issues with putting the flame out when I put the mug on (admittedly usually in crappy conditions). It seems to burn fine when it's just sitting inside the windshield. I've used the pattern you sent with the stove for the windshield so I think there are enough air holes.

I figured a half cm gap would stop that and help with uneven ground when the mug doesn't sit well on the stove as it's so small. If it won't work with a gap I'll maybe need to rethink.

Stu.

It'll still work with an air gap but the internal pressure will drop, so the flames from the jets will reduce in size. Also because the fuel is now burning in the stove and outside it'll use more fuel. Try and make any air gap as small as possible.

With regard to the stove going out, it's usually either putting the mug on a little too early or thinking that the thing's gone out when it hasn't ... there's a massive reduction in flame size when you first introduce the mug, which can often make it appear that the stove's out.

Glad I asked, thanks.
