My Hot Hammock Tarp testing continues...
This is a continuation or update on my progress of modify my hammock tarp to a hot tarp using a very small wood stove. The first test can be viewed here.
While the website was down I really had a bunch of time on my hands so I got busy and converted a standard 2QZQ GrizzBeak to a hot tarp vestibule.
This stove port is not completed. Just glued in place for now.
I will eventually add a flap to cove the hole on the outside when the stove pipe is not used.
I burned wood all day taking temperature measurements all around the inside of the tarp.
I had a CO monitor going as well. Since I packed snow all along the edges of the tarp to keep the wind out.
For my final test before hanging up the hammock and quilts I packed the stove with 36 charcoal briquets and timed the burn down.
Let me just say right now. Kingsford (((ROCKS)))
In my wood burning tests I was using dried yard scraps(pine, cedar, cottonwood) in 1/2" to 2" diameter about 7" long.
I would have to add wood every 20-30 minutes to keep the heat coming.
Once that died back. I cleaned the stove out with my poop shovel and packed that baby with charcoal.
It was awesome. I did not have to do anything for 3 hours. That little stove just pumped out the heat.
At the end of the third hour I tossed another 8 briquets while setting up the hammock.
Top number outside temp at 2PM. Middle number inside tarp at RL.
Hard to get good picts in a small tarp.
I hope you can see there is a great little warming/cooking area far away from the hammock.
Sitting in my camp chair with a small CCF pad under my booties I was able to heat water and cook a FD meal.
No gloves or hat required. I even took my down jacket off while cooking.
Once it got dark I spent about 3 hours reading waiting for the fire to die down so I could go to sleep.
@10:30PM it was 24F outside with slight breeze and 46F inside.
Woke up about 7:30 am.

what stove is that again?
In some mysterious way woods have never
seemed to me to be static things.
In physical terms, I move through them;
yet in metaphysical ones,
they seem to move through me. -

Nice set up man! I want to do this as well. Are you concerned about the sil being so close to your stove? What material are you using for your stove pipe heat guard?
Just when I thought you couldn't possibly be any dumber, you go and do something like this... and totally redeem yourself!

The hot tarp looks to be coming together well. How much of a temp difference are you getting inside.

30 + degree difference....that is just great! I'm glad to see you are still working on this and experimenting. Everything seems real promising so far, you've done a great job!!
Man you are living my dream! Wow what great setup!
Would you consider making two of these modded Grizzbeaks? and selling me One?

I love that you put pull outs on the grizz beak. You are doing an awesome job on this project.
You have to look at my picts really close. I have 3 Jacks or Better grip clips holding the material away from the stove in case the wind picks up. Plan to sew in pullouts once I have the exact places picked.
If the Grizz Beak touches the stove pipe it will melt instantly. Securing the GrizzBeak is critical. Securing the stove pipe is critical. Note the 3 orange anchor lines coming from the middle of the stovepipe outside the tarp.
As for radiant heat coming off the stove near the nylon.
It's hard to judge distance in the picture but I have the stove ~12 inch from the wall. Most of the heat is rising so the nylon is not even warm to the touch. Believe me I checked a lot.
Keep in mind, this is not a big stove. It will not run you out even if you pack it full. It takes some time to notice the temp has risen in the tarp.
Kifaru sells the stove port kits. They're about 35 bucks. You get enough material to make 2 3" ports. They also include velcro and grosgrain if you sew. As for the material it is called sylpad. Hightemp silicone over fiberglass cloth. I just used 100% silicone to glue the port in place. Plan to sew and make it look pretty later.
If you are serious about trying this I would be happy to offer suggestions
2QZQ makes the GrizzBeaks and you can't beat their prices.
Kifaru.com sells the stoves and stovepipe ports.
You just need some scissors and silicone. It's all pretty easy.
