My easy no weld rocket wood stove heater complete build with burn temps and use footage.

January 14, 2020

so I think I showed you on the last one
I built these Vogelzang exhaust or whatever adapters they come with this
attached there’s no way to take this out without cutting it really yes I could
try to grind this weld success challenge succeeded just had to grind here a
little got her out the other night when I was thinking about how to do this I had
a brainstorm why not use a Vogelzang kit to also
attach my burn chamber so this is going to go on the front of the barrel this will be the
burn chamber I’m gonna have to extend this a little bit I’ll have to use a
little short piece of pipe I put the thing on there you know I had it on there I got a marker and marked it out as close to edge as I can he wouldn’t go all the way up the edges I used a big
marker so I’m gonna do grabbed my grinder with a cut-off wheel just start
a cut good enough all right got my furnace cement from
last year when I did this I bought some more stuff at Menards but it was only
1,300 degrees this is 2,000 degrees I think I got this at ah a place that sells stoves so
I will have to get some more of this I just noticed I did make one
mistake i probably should have burned the barrel before I did all this but then
again this stuff is good for 2,000 degrees
I don’t think burning the paint off is going to get that hot should be okay
in theory we’ll see can always re-do it don’t want to drill through both pipes just this outside bit you also want to use a drill that’s
bigger than your screw so that’ll spin because your screw needs to be able to
grab the pipe if it’s grab it on this it’s just gonna bend your pipe instead
of cutting into it uhh self-tapping 1/2 inch hex screws there basically for stovepipe they
cost five cents a piece is that right anyhow so they’re hex screws hex head and flat bit and
those worked through the sides to hold the stovepipe I just did here here and
here because I want the bottom smooth or basically smooth so it’s easier to clean
out I didn’t want to screw sticking out I could still probably cut these off a
little bit oh ya I screwed up using that cement your supposed to damp the area with water before you put it on
you know clean it off good and all that shit I did none of that so….
oh wells It’ll still probably work if you build one you might want to do it
the right way though let me fuck up so you don’t have to. There you go, lesson to
live by you’re probably gonna have a hard time seeing this but I changed my
design slightly umn right now I got that little double 6 inch piece that’s still
attached in there I stuck some fire rope or whatever you call it right around
that six inch between the screws in it just for little bit of extra extra seal
really probably didn’t have to do that at all but I had extra short old piece
laying down so if your what the hell just stick it in there I put one screw
on the top of that elbow the upright ah upright is attached to it already
there’s just one screw holding that on top gravity in that’ll do the rest there
I don’t know if you can really see so there’s the heat riser inside of it I still have to
insulate with an eighth inch pipe but that’s gonna come later right now and
there’s that Vogelzang adapter like I showed you before gonna put another one on
the back at the exhaust it’s probably going to end up being up above this this
ring one thing to caution before dropping this thing
in here although with this big gap it will be easy to grab but if you didn’t have
if you centered your pipe better you might want to put some screws in the
this or something so you could pull it back out if you have to I made it to the store the other day
picked up a few things I got my second barrel stove kit I was wrong it was
actually $40 39.95 I thought was 35 but anyhow that is the only part we need
their stuff is just extra I grabbed an 8 inch trim piece to cover up our little oopsie that will be
nice oh also picked up a small bag of pearlite haha that was only like $12 $13
for that huge bag found it at a gardening’s place so that’s the place to
get it that’s for sure I probably paid $7 for those small bags
I was using I bought two of those bags so what I’m going to do now is uhh actually
I’m good dump some of the perlite in this small plastic barrel here and then I’m
gonna scoop out what I already put in the stove with the the umn clay because I want
to mix it with more perlite I could probably just go straight perlite but
perlite is so fine I want something a a little bit heavier to keep it together
not blow around easily I’m gonna seal it but still I don’t know I don’t I don’t
want to go I don’t really want go straight pearllite I don’t think show you what I got so far here you see that
lid doesn’t fit quite right because the barrels are slightly different all I do
is use some of the high temp sealant around the edges that Center um
hopefully will be covered up for the most part by the 8 inch pipe in that
other little bracket I bought so what I’m gonna do now is measure but this is six
inch pipe the bigger pipes eight inch so it should mean all I got to do is mark
around one inch down on this piece let’s see mark all the way around one inch
down all right right around here then then cut slits bend it over so this will fit
over the six inch pipe and Center and then I’ll put measure the other piece to
go on top of this and then I’ll fill it up with insulation and then our heat
riser will be done oh I have to bend the other end too probably there you go its not round right now because of this just have to push it a little bit lets go see if that will fit
gonna put some sealant around the bottom and I’m probably going to put some sealant around the bottom there we go so I put a nice bead on there ahh my hands are frozen up god damn hand cramps I tell you there the worst now come on baby get on there so there you go we got it got it on there I
got all my cuts centered pretty damn nice now I fill it in futzing around has caused some to escape
see if I can’t refill that before probably supposed to wear gloves using this shit but now
go right in and wash my hands so there you go It’s basically
done got her all sealed so it’s been almost two hours almost two hours since
I put that stuff on and I’m getting tired of waiting should be good enough I
just found this in my scrap pile from an old barbecue pickup barbecues that dump
I’m gonna cut out a section to go in my umn burn chamber lets more airflow
underneath got some paper from the other day and
part of a squirrel’s nest good old dry shit you see it’s sucking the smoke in ooooh! boy
do we have a rocket that pipe got oil on it’s burning off but it’s sucking
the smoke down back in sea oh you can see that then up here we had good rocket
going for a second all right
worked out a hole approximately in the back doesn’t have to be quite centered that works put the strap across the top
with the hooks you got to have decent sized hooks but then you can re-straiten your
barrel with the lid on I’am gonna go look if see if I have some more ah gasket I don’t think I have
enough but we’ll see so there’s a little bit of smoke xscape right here and that
is where the the gasket met yeah at first I had it overlapping but then it
was too long but then it shrunk again so that’s my problem I’m just gonna put
some cement right there just a little bead that will fix it check this out
FIRE! and even with that little bit of paint
that’s there check this out not much smoke at all and look we got a
what 24 inch chimney on this thing and it’s drawing like crazy no go back smoke
nothing lets see go that end so this is going to go on like approximately something like that all right so I bent over the end there
now I didn’t measure anything because i didn’t have time to look for everything so I just did it and hopefully it will fit that’s looking pretty darn nice
actually right there so now gotta fill that up first I’m gonna rap back I’am gonna find my gloves I got some gloves out here I’ve been using for insulation and for
this header wrap so don’t get that shit all over my hands first what I’m gonna do
like I did before is put this header wrap around use this extra bit and that’ll keep
it from leaking you know cuz we got all those little cuts so put this on first
and that way the insulation wont fall out as easy and it will insulate this little bit that otherwise
otherwise wouldn’t be insulated that’s basically it will just let that
hang it’s all metal it’s just metal mesh basically woven together it won’t burn at
least I haven’t gotten it to burn yet you have it [email protected]#king hot okay next
step is to get the insulation so that’t done nasty stuff ohh anyhow there you have it insulated I might just leave it like
this I could always seal this or something but this actually doesn’t blow
around all that easy you know once it’s in there it has some weight to it it’s
just really dust yet I mean you know when you’re pouring it so basically your
sticking it past the front of this that if it comes back further we’ll get back draft
I got my damper open I see a little bit if smoke coming out
from that match I should probably push the papers in just a little more and now it won’t smoke I am out of papers so I have to resort to cardboard which doesn’t like
to start as easy because its wet put it back up that’s a pretty good burn I mean 600 you know that’s kind of what it runs unless I get going good I can get
up to 700 over 700 ah temps in here well the wall is about 34F just over
there here’s the stove wall right there is already 60 and I don’t have the temperature gauge out here so you’re in here the far about thirty three or four degrees is right around freezing
today snow started to melt a little bit so it’s a little warmer day 300 degrees
right there more heats going through the system now that I shielded that I don’t
remember it being quite that hot that far down the pipe before just do temps up here 300 you know 400
closer to the top almost and then you know 550 to 600 I closed down the damper slightly temp
on the top of the sleeve 400 still pretty hot on the side 200 that’s a lot
better than a thousand though right now it would be over a thousand here you
know right down here it would be easy 1200 degrees where that fire is kicking
ass so that’s uh that’s a huge difference
well here let’s show you on the inside if I can it won’t read it too hot right there
at the feed tube 900 degrees you know and that the whole thing was that temp lets see
this stuff’s hot that’s like 400 too that’s a lot of raps you know all right
I just got the old rocket stove set up in the semi-trailer if I remember
right 60 or 80 foot trailer it used to be a used to be a reefer there and now I
got windows and as you can see I put a piece of metal across the window screwed
it in outside so there’s like no gap other than you know right around
where the stovepipe goes out all right it’s kind of loud because I
got the fan set up now right in the corner blowing across real nice it’s
getting actually pretty warm back here and I’ve only been running this I
don’t know 15 minutes something but it’s it’s heating it up nice in here all right let’s go outside okay so it’s
burning clean now I can’t see any smoke all right I got burning pretty good now
with I think some ash umn it’s not all good wood but it’s decent and we have some pretty
good temps going here but some of the highest temps I’ve seen I think and this might even do better or who
knows with once I replace this lid with a flat lid instead of this misshapen one
it’s all bent up right that’s my next project 703 let’s check the stove pipe
only 280 at the stove pipe so that means most of the heat coming out of this is staying in the
semi wow look at that 200 221 I will open this window and take this screen out wow hot over here gonna have to plug in the fan soon It’s really hot right behind it if I can see yeah maybe maybe you can’t the stove pipe I will turn my
flashlight on there you go right there it’s not much stove pipe
let’s check it one twenty only one forty hitting the roof that should be the
hardest exhaust point it’s right in there where exhaust is hitting smoke is
pretty much completely clear that means it’s a super efficient burn that’s
pretty decent 170 down here fully insulated and look at that still
40 degrees only down here see that there you go 20 degrees because of the
insulation 40 you can see you’ll see when the installation stops 60 there you
go now we’re getting into some heat pretty cool ehh I need to build more rocket stoves man I forgot how much I love this thing because I haven’t
been using it and now that I have it out in the semi I’m going to use it more so

  1. I admire your initiative. I would like to see a follow up video in 3 months. Rocket stoves burn exceedingly hot and create a lot of fly ash. I would like to see how the metal in the firebox holds up, how you dealt with ash buildup, how you cleaned out the ash and whether the perlite insulation around the pipe served any purpose. We can learn from your experience. Thanks for your effort and sharing.

  2. Based on my own research and prototype builds in the past 4 yrs, the continuous high temps from use will cause the metal to fail.

  3. The damper can be removed by pushing the handle in and turning the handle without moving the damper and presto by pulling and twisting the handle comes out and the damper is free.

  4. Clever use of materials… not sure how long the riser tube will last, but your method got 'er done…
    And that's what counts.

    I built one with an Insulated firebrick burn chamber and riser… I'm getting well over 1200°F on the top, and up to 800 to 900°F on the sides when burning well.

    Looking forward to making stove 2.0 which will be a batch rocket… so many innovations on YT, and I want to incorporate them all in one.

    Check my channel. There's a quick wordless vid of 1.0 and one of a failed attempt to make an external batch box… big mistake… 2 weeks of my life gone…

    I followed up that failure by making a larger burn chamber, so I could burn cordwood (verticle), and have longer burn times between fuelings… now I need to use an insulated flu to increase draw…. it's always something.

    Keep building… rockets sure are fun…

  5. Walker Stoves has built his burn chambers and riser out of refractory board and then lines the burn chamber with a high temperature alloy used in furnaces. This seems to be overcome all the metal spalling problems from burning at 1000 degrees.
