  1. I love you videos… I wish I lived close to you. I'd probably try to come help you (free labor) every day after work. Lol
    Question: is there a reason you didn't weld completely around the wood supply areas. I see one gap on the top side and the sides on the bottom where the ashtray is. Love this stove and will be building it soon. But I wanted to ask questions before I welded it solid and screwed it up.

  2. I'm a boilermaker that's been in the trade for over 30 years all I'm going to say is this guy is pretty bloody good I honestly think you are not dual trade you are triple trade add boilermaker as well mate .Thats some of the best plasma cutting if ever seen free hand with massive thick chalk lines and your welding is pretty good as well.So Can This Guy Weld Yes

  3. I really didn't think that the draft from the flue would be that good, but I was pleasantly surprised. I guess that you could pipe the exhaust outside without any problems as well.

  4. Nice build…. But to me, there's something missing.
    Nearly every rocket stove I've seen built has a fundamental flaw, not in the design of the body of the stove or the build, they're all great. It's a misunderstanding of the principal of how a rocket stove operates and the benefits of a correctly operating one.

    The concept of a 'J' tube was to cut down on smoke when cooking using wood as a fuel. Rural Indian households would traditionally use an open fire for cooking, the smoke issued led to high levels of lung disease. Using a J tube led to better combustion and cut down on smoke.
    The rocket stove advanced this idea so that the exhaust gases would have almost no particulates. This is achieved by extremely high combustion temps. To achieve this, maximum draw is used, the combustion chamber is insulated and the first part of the stack is lagged. This is to retain as much heat in the combustion chamber and stack to achieve fast and total combustion of the fuel. The exhaust gas is what is used for heating, rather than the body of the stove. Hence the sound of the running stove and the adoption of the word 'rocket'.
    Designs for space heating sometimes incorporate a barrel that sits over the body of the stove and stack, the exhaust outlet can exit the side horizontally because the draw for the combustion is created by the extremely hot stack inside.
    The best rocket stoves have a ceramic chamber a thin walled insulated ceramic stack because this part needs to heat quickly for ease of starting the combustion and achieving a draw quickly. If the stack is simply vented normally without the barrel chamber, the draw will tend to happen naturally, but if covered by a barrel as used in a mass heater, then the draw needs to develop quickly.
    Hope this is useful 👍

  5. Very interested in your work. Thinking about alternative ways to heat the chill Pommie home I was wondering if anyone had ever to reproduce the simplistic method used by the Swedish Admiralty in the 19th century? They had a furnace to heat cannonballs and red hot cannonballs were carried around the admiralty building and positioned in holders to provide heat in the various offices. It occurs to me that a system like that with an efficient rocket stove at the core could avoid the issues with in-house installation and flues etc. Yes cannonballs are hard to come by these days… but a foot length of railway track might be a handy alternative. There could be one in the stove and one in the house, swapping them over then it cools.

  6. So I'm trying something. Instead of attempting to talk my husband into building one of these, I'm just going to casually watch the video where he can see it until he gets interested on his own and takes off.

    I'll report back with the results.

  7. Hi this is Raymond from Scotland. Can I pick your brains. I am building a stove same as your shop heater and can only get 4” box section do I use the same sizes for the Venturi vortex or do I take a third of your sizes as mines is only 4 inch box.
    Keep up the great videos
    Regards
    Raymond

  8. Hi, bought plans for the stove, missing size of the hole between burner and riser, also diamension for the pipe welded to the bottom of the riser. Look like something missing in the plans.

  9. 155-100…. I'm sorry to be disrespectful, especially with this likely being my first video of yours, but it truly amazes me that many people who work with metal just don't seem comfortable with numbers. I'm sure it's different with yourself though, dealing with the recording process throughout
