Great video, I do not want to squat and the extra height is welcome. The feed ramp excellent but sheet metal and a couple of bolts, keep you from getting a broken foot, pot holder,( I know you don't need one here ) one of your sheet metal bands, notched for air flow, works great. Lastly many forget, lift your pot and drop fuel in the top, works especially well with the extra height. Thank you. Last thought when camping I used to take two blocks and build the rest on site, clean up of the mud base was no problem.

Nice, liked, thanks for sharing 🍀💐🌈

[@jillnachtsanger4205]

Love watching you battle gamely uphill with sand, cement, cardboard, power tools and hammers, but man, it is so much easier to use fire brick. We make our stoves portable by using angle iron (usually cut up old bed frames) and threaded rod to form a cage that holds the bricks firmly together. To move the stoves, simply back off on the threaded rods and handle the bricks separately. Quick, and with the stability of a casting. Set the stoves up for maple sugar season, dismantle them for compact storage afterward. Never spend a dime on fuel. We do keep a stainless steel rocket stove for camping. Double walled and insulated, weighs 18 lbs, has legs and a handle. We do like our little luxuries.

[@GreenShortzDIY]

Thanks Jill. Having built a variety of rocket stoves now (including one in firebrick), I will agree with you. Here is my firebrick rocket stove, if you are curious: kzbin.info/www/bejne/hXuQmIKoaM6Eas0 How cool that you use your's for maple syrup production. I love to see video of that. I think I will end up replacing the flue pipe in this project with firebrick and making the riser shorter. I really want the flames moving through the oven. And, for the record, my channel is about the journey, and not necessarily first finding the easiest path. I love the experimentation process, what some see as failure, I see as iteration. Not saying I got that sense from your comment, to the contrary, it was encouraging. I do intend to migrate toward simpler and easier as the process goes forward, but it will always be the uphill battle...and I hope to pursue that in a gamely fashion. Thanks for watching.

[@stevenrldenault7451]

Hello, just a question regarding the basic tech of rocket stoves. Is it not about having an insulated chimney that gasifies the wood and emits no smoke, achieving high heat and not wasted gas due to an insulated chimney? Steve . just asking.

[@dogrudiyosun]

you also must be stupid

[@MidwestDavesGoldProspecting]

Cool video. Ramp is wider than firebox opening which allows wood to grab the firebrick and stop. Maybe narrow the ramp to match the opening ?

[@GreenShortzDIY]

Thanks for the suggestion Dave. I think you are right, that a matched ramp width would perform better. I’m using salvaged steel and standard sized brick. Making them match here would have been a lot of extra work. Although I could have welded inserts in the ramp. Thanks for the suggestions. Thanks for watching.

I got this one at a building materials store. Not a home improvement store. This is the kind of place that has a large outdoor area with stacks of brick and lumber. I’ve got one near me that doesn’t have the flue liner and masonry stuff. A place that has everything is fairly specialized. Hope this helps. Thank you for watching.

rocket stove making is the most useful skill for emergencies I can think of... but it's morning -hmm... what's more important?

[@theword4501]

Oh darn... I went to buy one...but it was too small for what I was going to use it for... Are you making any... The size of your bucket rocket stove ?

[@GreenShortzDIY]

In the end, I think the flue pipe is too brittle to handle the heat of a rocket stove fire. I did build one with a cobb liner, but that may restrict the size of the chimney too much, based on the size you could find. Let me know what specs you are working with and I’m happy to offer some suggestions. Thanks for watching.

[@jerrycampbell9376]

Will this run hot enough to melt small pots of lead? I've been using a Coleman stove, but sticks are far less expensive that liquid fuel.

[@GreenShortzDIY]

Jerry Campbell I do think a rocket stove could melt lead, but not in this configuration. I think you’d want the lead crucible closer to the fire.

[@ruthdoyle9085]

Try styrocrete. Prolly won’t crack if reinforced or wrapped with mortar soaked canvas drop cloth...very insulative and the styrofoam doesn’t noticeably melt. Very lightweight...

[@GreenShortzDIY]

Thank you for the suggestions. Thank you for watching.

[@forestfairness12]

i like your honest inventive trial and error approach... just to be aware, most of these stoves, except perhaps the perlite concrete one are not really true rocket stoves... over 50% of rockets stoves on youtube are not true rocket stoves, so the term is being widely misrepresented now.... a true rocket stove uses lightweight porous insulation for burn chamber... fire brick is too dense to be good insulator, tho it can take high heat... maybe surround the fire brick with some kind of insulation, and it will simply take longer to warm up enough to have the rocket stove effect of being less polluting....

[@GreenShortzDIY]

Thanks for the feedback, Forest. I agree with you...the term Rocket Stove is used to describe many stoves that aren't true rockets. I do plan to make a true rocket stove sometime this year. Thanks for sharing your tips. Thanks for watching.

[@BeatVids]

@@GreenShortzDIY Hey man, I'll be on the lookout for this. I'd even buy a true rocket stove if you are willing to put it out on the market.

[@ronaldroberts7221]

Could you share what the details are for a true rocket stove? I've noticed that there are a lot of variations in these small youtube stoves...

[@forestfairness12]

a true rocket stove has an insulated burn chamber, using some kind of light weight low density fireproof material, such as vermiculite, rock wool, cinders, type material... this material is packed between two layers of usually metal, sometimes other materials.... the insulated burn chamber once heated up reduces pollution greatly, and was designed for third world people who often cook indoors on an open fire.... many so called "rocket stoves" follow a similar design system but are not insulated at all, or insulated poorly with too dense a material, to reduce the pollution.... if using this type of fake rocket stove outdoors, not such a big problem.... but if wanting to reduce pollution, and get quicker cooking time, and more efficiency, the double wall insulated rocket stove system is important... there is another type of stove call a "tlud stove" (top lit under draft), or "gasification stove" which can accomplish a cleaner burn without the need for insulation.... but it does require getting more technical with the proper design, knowing just where to place the holes in it, which make it a more bit more technical build system, but no need for insulated burn chamber as in rocket stoves, just need to follow a well designed diy system.... many examples on youtube, and one advantage with bigger tlud stoves is that you can make biochar as well when using it... here is a demonstration of commercial gasification stove: kzbin.info/www/bejne/hqindJ6tf82ar5o.... but many do it yourself models on youtube as well... aloha

I would have loved to buy 2 of the rocket stove kickstarters but you don't ship to Canada. Do you think this could change in the future?

[@GreenShortzDIY]

Hi Frances. The short answer is yes. I wanted to keep the Kickstarter part of this campaign simple, so I just shipped to the US. I did have one request from Norway, so I found out what it would cost and let the pledger know. He was cool with that, so I created a custom reward. I will be glad to ship to you the same way. Let me fulfill my orders for the Kickstarter and I'll see what stoves I have left. If I've run out, not to worry...I'll be placing another order soon. Send me an email at the contact page of greenshortz dot com and I'll reply with some details. Thanks for your interest.

[@ADHDAdventurer]

Where in Ga are you?

[@ShannonSmith4u2]

Well done. The pizza oven door cannot be more than 61% the height of the dome, it can't trap enough heat, if it's taller than that. If you want to cut any fire brick or the chimney flue, put a ceramic cutting blade on your Wormdrive skilsaw, cut are much faster and much easier to hold in place. Plus, set your depth, make a pass, drop your blade a bit, make another pass. Much more torque and HP to cut than the unstable cutoff. It is at least 4 times faster to cut.

[@forestfairness12]

i tried a chimney pipe once like this and it cracked... let me know if it cracks over time...

[@GreenShortzDIY]

Thanks for the heads up, Forest. Thanks for watching.

[@MRnounoursSQ]

I don't think the flue liner will last it's not build for high temperature but at the place where I get fire brick they have flue liner kind of build like fire brick and those flue liner will take the hi temp

[@GreenShortzDIY]

I’ll be keeping an eye on it. I did add another thin fire brick standing up in the back of the firebox. I was noticing a few hairline cracks where the flue pipe was nearest to the fire. Thanks for the feedback.

[@offgridmanpolktn]

@@GreenShortzDIY I hope that the extra brick helps, but suspect that eventually your flue pipe is going to disintegrate. Have taken down several houses where they are just a standing column of powder being held in place by the chimney block or bricks around them. Think it is the temperature differential between the inside and outside that is causing the cracks you are seeing already. Perhaps once the pizza oven is installed this degradation will slow down, with more of the heat being held down around the outside of the pipe? Actually came to make a suggestion though, have you considered using a section of double or even triple walled wood stove pipe? The cost would be a little higher, but wonder if the benefit of maintaining the higher temperature inside of your flue would be worth it? My understanding of these types of stove's is you want the higher temperature to carry further through the flue to help cause the rocket effect.

[@putheflamesou]

where do yo get a liner for high heat??

[@MRnounoursSQ]

At the place where they sell brick here where I live they actually have liner that will take high heat more then the regular one but don't know if it's available every where the salesman told me it was a special order and they have some left and they don't keep those liner regularly. he told me they done some test whit them and the regular liner, they heated them whit torch until they got red and they trow cold water at the the regular flue exploded and the grey one like fire brick did not!!!

[@Speeglelookingglass]

Is your little stainless steel rocket stove available to buy yet? I'd like to buy one but that has an extension on it where you can screw it into a concrete pad. I get a lot of things stolen from my yard. Also, if I screw it down to the concrete pad, my cats can sit around and enjoy it without knocking it over. I feed homeless cats and they get pretty cold and would enjoy sitting around it.

[@GreenShortzDIY]

Hi Laura, I have a few left and will get them up on my web store in the next few weeks. Not sending to Amazon at the moment. Watch for an announcement here on the channel. There is a spot that you can attach to a concrete pad for security. Thank you for watching and for caring for your local cats. :-)

[@Speeglelookingglass]

@@GreenShortzDIY thank you! Hope to hear from you again

[@putheflamesou]

can you get a flue pipe that would take the heat....or is that tooooooo safe and sensible and liberating?

[@GreenShortzDIY]

Ha. Well, I think it may need to be a different material. Or maybe lined with fire brick. Or made out of clay. I do have some of that on hand. And I do plan to make another Cobb Rocket Stove soon. Thanks for watching.

[@truckerdaddy-akajohninqueb4793]

Look up ppotty1. He makes the bottom of the burn chamber cylindrical. It improves the quality of burn. It swirls. No ash. Burns hotter. A tin can might do it? I like these brick rockets

[@bradjcarlson]

if you use the thin fire brick, and cut it down to size, you could line the clay chimney to make it more resilient. Place the first row accross the fire box bricks that you can see from the top of the chimney. Then cut to fit the other two sides and place them on the other two sides. Then you can build up to the top from there for a tight sealed fit.

[@GreenShortzDIY]

I like your thinking Brad. I have added a thin fire brick to the back of the firebox, but I may need to go higher with them. Thanks for watching.

[@minerdad02]

Hey I bought just that off amazon recently nov 2018

[@MasterKenfucius]

Did you build your final contraption?

[@GreenShortzDIY]

Contraption is the right word. I've got the base done...which was a welding 102 for me. It's posted...my most recent video. Part two will be the construction of the oven. Thanks for watching.

[@MasterKenfucius]

I'm curious as to what you're going to end up with. I'm a bit incredulous that you'll get enough heat buildup in the oven to do a pizza. Part of the reason it gets so hot in the dome is the radiant heat. By channeling the heat into the dome from the stove you lose that heat source by radiation. Did you consider that?

[@GreenShortzDIY]

@@MasterKenfucius This is an experiment. :-) My plan is to line the arch of the oven with rebar with a layer of loose perlite over it, covered with a cement and perlite mixture. My hope is that the rebar will absorb the heat, hold some of it and then radiate down onto the pizza. The flow of heat through the oven to the chimney in front should help the cooking of the pizza as well. I'm remaining cautiously optimistic. I welcome your incredulity until the results are in. :-)

[@MasterKenfucius]

@@GreenShortzDIY I know perlite and vermiculite are excellent insulators, but I don't know much about their ability to retain heat. I made a tandoor oven by putting a terra-cotta pot inside another and insulating the middle with vermiculite (from a youtube video) and that turned out pretty darn good. I get 850 degrees inside that sucker with a couple of hands-full of charcoal. It's amazingly efficient. I can cook chicken tenders in 5 minutes on a skewer inside there. And it stays hot for a loooong time. One time I woke up early morning and it was still 300 degrees inside there! Blew me away.

[@GreenShortzDIY]

@@MasterKenfucius I haven't used vermiculite yet. How was it different than perlite, in your experience? To clarify, I'm not looking for the perlite to retain heat, but rather keep it in the rebar layer below it...and to prevent the cement above it from cracking. Your Tandoor sounds awesome. I'd love to see the video you are talking about. Thanks for the feedback. Wish me luck. :-)

[@moondazed5451]

You didn't put the grating at the bottom to leave airspace beneath the fire, was that on purpose? I'm pretty new to rocket stoves, I'm just curious after watching the succession of these videos :-) Edit: I wish I'd seen the Kickstarter in time! I'm glad it was successful :-D

[@GreenShortzDIY]

My initial thinking was that the ramp would suspend the wood letting air flow underneath. This works until the wood gets to short and drops off the end of the ramp. I might weld a grate on the end of the ramp after all. Thanks for the feedback. Thanks for watching.

[@RDALEHOUSTON]

did u use metal cutting disc or stone cutting disc

[@GreenShortzDIY]

[@cy8646]

Hey, new to the channel. I want to build a rocket stove myself to dispose of wood scraps and I'd also like to cook outdoors, off grid and put them to good use! You've gone through a few iterations of stoves made with concrete and it seems added hassle with trying to make form work that you have to remove. I was considering concrete too as I would assume it wouldn't get as hot as terracotta or steel. I don't know if you've thought of this or have done this in an older video I've not come across yet - but have you not thought of using the chimney flue as your form work? You could cut it at 45deg so they join at the base and then exit. This way you might also get some insulation without having to alter your concrete mix too much. Let me know what you think.

[@GreenShortzDIY]

Hey Cy, sorry I’m just seeing this comment. Some interesting considerations here. I did use a larger flue liner as a form to hold a inner core of cob. It worked pretty well. I didn’t cut it though. Just did a firebrick firebox with a grate. An L type rocket stove versus a J type. The L type stoves have always worked the best for me. You can find that video by looking for a stove I refer to as Max. I planned to use it to melt aluminum, but it didn’t work for that. Then I made it into an outdoor shower heater. It would be really great at what you are wanting to do, but I imagine you have a solution given that your comment is 3 years old. :-)

[@crusader2.0_loading89]

Nice vid...can you adapt it to be a portable rocket mass heater once you have added the top? That might be interesting

I enjoy watching your videos on rocket stoves. But I would like to see you do a design change that I think will significantly increase the efficiency and make your stoves more Rockety. A taller flue will create a higher air draw ratio at the fire source. But more importantly, I would like to see a vertical stick feed with at least a 12" horizontal distance between the feed and the flue. Creating more of a "J" design. This will create a horizontal fire draw before the fire enters the flue. I really want to see your take on the comparisons with a horizontal draw v/s a near vertical draw that you have in your designs.

All of that extra cutting that you.did to make the x and the vertical cut, I'm not really sure why you didn't just cut all of the way through. I guess that you were in a hurry, huh? Anyways, I going back to watching your video. I'm stuck in Michigan, broke, below zero outside, no materials to make anything with. Thank for the video.

안녕하세요i like this video you make mistake a little it is make me smile good luck haha!!!

I'd cob over the structure to insulate the riser and also tie it all together.

[@GreenShortzDIY]

Interesting idea, Kevin. I’ll give that a try. I’ve got a Cobb furnace planned as well. Thanks for watching.

[@mio.giardino]

Your cob oven isn’t constructed properly as there isn’t enough mass or insulation to retain the heat...it looks like you were building it for aesthetics rather than function. The one my dad built can & has retained heat, hot enough to cook, for 12+ hrs because he insulated it with a lot of mass.

Ha. Very true. Thanks for watching.

[@littleshepherdfarm2128]

Actually, having done many choppings on blocks like this, there IS a way to use a regular hammer to crack that block correctly. Use the claw end underneath after scoring it and tap GENTLY. LOL. They make hammers just for this approach as well but I've never had any problems using a straight claw type hammer for it.

[@heatherclark2623]

@@littleshepherdfarm2128 - - I was wondering about that! I was actually picturing a VERY skinny chisel or narrow (~1/4 inch [~4-5mm for our friends not stuck in imperial]) slotted screwdriver, and tapping on the end of its handle gently with a hammer. Do you think that would work? And where would you start? I'm thinking start in the middle of one of the lateral edges, and moving toward an open end. Then after completion of that half, I would think you'd move to the top of the unfinished/remaining half and chisel toward the open end. Then move to the middle of the remaining central piece and chisel outward, one half at a time. I would think holding the chisel/screwdriver at a 45 degree angle, and continue gently carving out a groove. What do you think? Or even start first in the middle of the straight line he scored out, the one bifurcating right down the middle. This would create smaller sections to work with, and translate less vibration and stress across the entire brittle surface area. Fascinating stuff. I love the depth of knowledge and the intelligence being expressed by commenters.

[@littleshepherdfarm2128]

@@heatherclark2623 I wouldn't use a screw driver for that at all because the claws on your straight claw hammer are much much wider and will strike a wider area. If you use a flat tip screw driver you're likely going to end up breaking the brick where you don't want it broken and you'll probably be there all day doing it. The idea is to score the brick so your claw has a line to follow and the concrete in the brick will also have a path to follow. Then after scoring the brick use the straight claw end of your hammer to chisel gently along that line. I personally like to hold the brick down on a hard surface of concrete with the scored end hanging off of it so that when the concrete breaks there's nothing under it to cause resistance and make the brick break apart. It does take practice to get It right but that is true if you use the chisel type hammer they make for this. Give it a try and see if it works for you is all I can tell you. If it does If love to hear from you about your experience. In the meantime I hope you have a great week and weekend

I am just a simple unfrozen caveman lawyer, so I am not familiar with your ways! But, I watch a lot of videos on how to construct a rocket stove and my first obstacle is I don’t have the right tools. My second obstacle is I go to Lowe’s and ask them for vermiculite and they point me to “horticultural vermiculite”.. is this right, the third issue is where are you getting your supplies from. I realize the vermiculite/perlite was from a prior video but still, where did the terra cotta come from. Help an unfrozen caveman lawyer out 🙂👍

[@arkansasmountainman]

I believe that is the perlite they use and the terracotta tile is flue liner for a fireplace flue. You might find it at a lumber yard oy a masonry supply store. I saw no one had answered your question. Hope it helps. These generate a lot of heat and that tile, as he said, is not designed for the heat. I understand from another comment that there is a tile that will resist the heat. I'm sure it's more expensive.

[@JRFew]

I'm not clear on the references to all of the past videos but perlite and vermiculite are used similarly in agriculture. Vermiculite should be handled carefully given asbestos/mesothelioma concerns. Previous vids show mixing perlite with water and cement. Given that the insulation, air spaces, are what you are wanting it may behoove one to mix the dry perlite w your slurry. I can't see vermiculite functioning to insulate in a composite like this because it absorbs water. My understanding is that vermiculite is used as fill in spaces between a flue and a masonry wall. When the weather clears here I have a project planned to build a rocket out of an old oil can and chimney pipe using some material, perlite, clay straw, etc as infill. This would sit on either a fire brick or cob combination firebox. Thanks to everyone for the videos and learned input. Cheers.

raise your pizza closer to the ceiling of the oven ?, stack a few bricks inside, then get a round pizza stone, sprinkle a little cornmeal over the stone, and presto, low-cost solution and pizza from your bread oven, if it works, make me one please, extra cheese, please

Add a little carry handle or a place to hook it onto a back pack to make it easy to carry around...

[@HealthyFamilyVarietyChannel]

I think this design is a bit too heavy for that. As is, this one is 'glued' to that heavy concrete slab.

[@scottpowell6145]

Hi Tom, Where is the floor of your fire chamber? I have been watching your videos almost all night and it seems like you are missing the basic concepts of Rocket Stoves. You should have been using the concepts of the rocket mass heater in your greenhouse. It's okay if you wish to reject my post, because there are a ton of videos on KZbin which sufficiently illustrate the proper build of a rocket mass heater.

[@GreenShortzDIY]

I can't argue that the stoves I am building are not full-fledged rocket stoves. I do plan to build one at some point. I actually need to do some research before I'm ready. I always appreciate honest feedback, especially when it is presented nicely. So, thanks for keeping it positive. And thanks for watching my videos all night. :-)

LOL, I’m glad I could inject some humor into someone’s day. By the way, I thoroughly enjoyed and gained some great insights into the construction of a PROPER rocket stove! Good work!

I cannot link to YOUR videos. I get a 400 error, even though I can link to other videos, not in your series. Hmmm. My comments: math helps. Look up the ideal angle for the feed. There are excellent other bits of information like that. Concrete ??? Hmmm. Also, I have bought various systems to test them. Light metal, bad angles for the feed tube, can't put in larger sticks, ( so no Long Burn), no space below the feed, having to bend repeatedly to do a lot of restocking, poking the fire, etc...I tossed all those ideas out. Look at the idea of a properly angled vertical feed with sufficent air beneath the wood input, and a horizontal burn chamber. The horizontal chamber creates torsion, that way you eliminate smoke, AND you get clean, environmentally friendly stuff coming out the vertical chimney. Sorry I can't link to you. I enjoy experiments. Have fun.

[@GreenShortzDIY]

That is odd, Scott. Thanks for letting me know. Interesting to hear about your testing of different rocket stove units. I will be doing a video soon with a horizontal burn chamber...a proper rocket stove. Thanks for the feedback and for watching.
