Testing out Dave's Bullets and Real Survival - Silicone baking mat Stove Jack for $50 Tarp-Tent with DIY wood stove

So I have been in consultation again with Dave of Dave's Bullets and Real Survival youtube channel - out of Canada. He is very helpful and his stove leg design was brilliant. So I decided to take him up on his Silicone baking mat idea. (video)

So I got the silicone baking mat at Target. It's probably not the same dimensions as the one Dave used. I'll have to double check...

Great price, not as large as named brand (silpat) but gets the job done.
yep - just as I suspected.

16.25 inches (L) x 11.42 inches (W)
I think this will still work.
 SILPAT® Baking Mat | SILPAT® 16 1/2" x 24 1/2" Full-Size Silicone Non-Stick Baking Mat.
Yeah I think Dave also has the "half sheet" size.
So then Dave said the only way he could attach this to the tent - tarp polyethylene - was to use crazy super glue to attach duct tape to the silicone - since otherwise the silicone is non-stick surface.

So I found some crazy gorilla glue we still have and I have some duct tape. Then I will cut a 2 1/2 inch diameter hole for the stove pipe.

Next I need this 3 inch 90 degree. This item is discontinued - but I found one used and sure enough it's still at the same hardware store. So they are holding it for me behind the counter - it's 90 degrees and corrugated - 3 inch stove pipe - so it will dissipate heat very well and also not leak smoke.

I hope it really is 3 inches - I checked it last time. But it's hard to believe I found this !!! 

I checked Imperial Manufacturing website and they don't make the 3 inch size corrugated elbow anymore. https://www.tinywoodstove.com/product/3-stove-pipe-90-degree-elbow/

3” Stove Pipe 90 Degree Elbow

$40.00
Wow - that's a ton of money since the 6 inch one is only $13. So the used price is only $5.50 I think - I'll find out tomorrow - it's around $5.

Oh wait - his angle is not 90 degrees - it's 60 degrees.... oops.

So maybe I won't get that one?

So I got a 10 x 12 canvas polyester tarp - with grommets. After the 11% rebate then it's $50. It's heavy and pricey but these tarps are very strong and should insulate a lot and are water resistant as they're treated with silicone.

So the wood stove is $12 for the legs and $12 for the elbow and $12 for the rest of the duct pipe and $12 for the damper.... so it's a $50 wood stove (nuts and bolts).... plus the stove jack now as $8.

and the tarp tent with tarp clips - so that is $55.

So that means a Hot Tarp-Tent set up with stove for a total of about $125. I still need to get another $3 tent for the end door. But I maybe able to stake out the poly-canvas tent for a smaller set up - so I have less room needing to heat up.

My new Stove Jack!! - Duct Tape is so I can then Duct Tape the stove jack to the tarp


Ok thanks - based on the mini-debate in your comments, I took out the baffle. So I have the damper higher up. Since it's a small stove with the insert - now I can load more wood. Hopefully I can get a half hour burn time. haha. But with the damper - then an hour I'm guessing. I can always make another baffle - but I was getting too much back draft smoke when opening. Not a lot but I really don't want any if possible. And with a smaller stove - I think the baffle was pushing it. I started out with a baffle half the size - so I can try that again if I want a cleaner burn.

So I have the crazy glue curing for 24 hours. I glued it on a few hours ago and now cut the hole - so I have the silicone stove jack around the duct pipe. I'm thinking I'll just leave it on - as I'm not planning on back packing. Either bicycle or car - so I have the stove kit in a duffle bag. haha. It weighs less than the tarp! I can probably get the tarps in there but obviously don't want to rip them. So anyway -  with the Two Dog stove. That does have a baffle and no damper. But before I didn't close the front vents - now I will do so. I didn't realize that closing the front vent is the secret to the baffle getting hot enough for the blue flame secondary burn.

Thanks again to Dave for answering all my questions! This design of his looks to be another brilliant one! The stove jack is flexible and about the same size as any other stove jack - only it cost only $8 (plus the duct tape and crazy glue I already had)... A typical stove jack costs $38 minimum and you have to sew it on.
