Stove jack and fire proof material for a tarp?

[Beast 71]

I was reading a thread that Smokehouse started about his tarp and packable wood stove it looked really neat (sorry I can't figure out how to link to it). He was cautioned several times about the nylon burning or melting, his gear burning, or god forbid, himself burning . He answered that he was aware of the dangers and that he only used the stove when he awake and near enough to the stove to attend to any dangers.

That got me thinking, since learning to sew recently, about designing a fire proof tarp with a stove jack . I'm clumsy so, me being near my stove would probably be a bigger liability than having it unattended, and if I'm going to carry a stove all the way into the woods I want to be able to use it while I sleep (of course taking precautions against CO poisoning). A matter of fact I wood like to be able to stoke it up a few times during the night to stay warm.

What I don't know is;
What would be a good material to make it out of?
Would the cost of the material make it cost prohibitive?
How heavy would the cloth be?
Would the Whole thing need to be fire proof or just the stove jack?
How large does the tarp need to be to keep the stove away from the hammock?
Do the hammocks and quilts need to bee made from a fire proof material?
Would fire resistant be good enough compared to fire proof? (ie. using fire proof for the jack and fire resistant for all else.)

I think this idea might work if it doesn't cost an arm and a leg for the material and the weight of the stove and the tarp can be off set by bringing less clothing, insulation, and no fuel. Any thoughts?

The SF-G or SF-R types are supposedly good. (silicone-impregnated fiberglass)

If you call, you may be able to get the straight material -- not finished as a "blanket" with grommets and cetera.

I don't know where to get the high-temp grommet that fits right to the pipe...

I have used Kifaru Tee Pees (Ultraligh) and they are just SilNylon, nothing special about them. If you are trying to build a fireproof tent I think the weight savings of off-setting your insulation would not be there. The lightest thing you can do is be careful!

Smokehouse and Turk have both built very good hot shelters; and the hammock hut by JRB would be a great one as well (I think that is what Turk started out with). You can buy the stove boot many places, including Titanium Goat and Kifaru.

In the Kifaru Tee Pee we keep the fire going all night while we sleep; 2 guys plus gear in a 4 man Tee Pee, very easy, nice and toasty.

What would be a good material to make it out of?
I would use SilNylon for the tarp (top) and maybe DWR for the sides.
Would the cost of the material make it cost prohibitive?
No more than anything else this big. For me, and the limited number of times I would use it, yes; for you, only you can answer that.
How heavy would the cloth be?
1.3-1.9 ozs per yard
Would the Whole thing need to be fire proof or just the stove jack?
No, just the stove jack (boot)
How large does the tarp need to be to keep the stove away from the hammock?
Generally you need more than 12 inches to combustables/meltable stuff. I think the Kifaru stoves say 11 Inches from the tent wall.
Do the hammocks and quilts need to bee made from a fire proof material?
Not if you keep them away from the fire!
Would fire resistant be good enough compared to fire proof? (ie. using fire proof for the jack and fire resistant for all else.)
Yes, but again, I don't think it's needed.

Excellent info, Hogn8r!

I probably should have specified... the material from www.welding-blankets.com should only be used for making your own stovejack! The lightest weight silicone-fiberglass fabric I could locate was 18 oz/yd^2. That would be a VERY heavy tent.

I'm pretty sure the custom JRB hammock hut that was built with a chimney flap was made from fire resistant material. Remember, Pan was one of the folks cautioning about the risk of fire.

Not to derail the conversation... but do you sleep in a hammock in this setup? If so, how?

I don't but Smokehouse does; check the shots in the
Smokehouse in action thread.

Check out turk's project here:
http://www.hammockforums.net/forum/s...ead.php?t=2244

It's the JRB Hammock Hut, modified with a fire resistant stove jack to deal with way below zero Canadian winter trips.

Search for "turk stove jack hammock hut" for a couple other threads on it.

I found this video the other day. Worth a look for those that want to sleep in a hot tent.http://www.youtube.com/watch?v=w492-...eature=related Sleeping while stove is working or still warm are not advised. I know this is an EXTREME test, but the results don't lie.And here.

And here.

Just be careful!!!

The JRB Hut that Turk used was one of only two early prototypes, hex shaped vs the diamond that was later to become the JRB Hammock Hut....Those two earlt prototypes were made of a fire retardant material that met CA FR specs... It was approx twice the weight of sil... Came in at 4 pounds total weight.

Currently the silnyl JRB Hammock Hut is out of production... May bring it back, but only on a special order basis.

JRB does not support stoves in tents... With or without stove jacks... Turks stove modification was his own and not a JRB item.
