I decided to launch this blog to accommodate my new website “miniwoodgas.com” in the hopes of motivating others who have built working gasifiers to share their data with others who may be wanting to try this for themselves. Thanks, Flash001USA

    Howdee folks,

    Just a wonderin’, do you think that there wood be any value in designing a spark generator that can be easily built at home?
    The ones I make have computers in them, which makes them impractical for the home builder, but I think a more practical one can be made with a couple of automotive relays – and other car particles.

    One relay, along with a suitable capacitor, can become the ‘clicker’, and the other can serve as the ‘set of points’ that will drive the spark coil.

    Off the shelf components could be used for this, thereby making it super simple to build.

    Once the sparker is up and running, there wood be no need to keep a lighter handy, while waiting for gas flow at the flare port to ignite.

    It’s widely known, among me, that this is a wood idea, oops – good, idea πŸ˜‰ .

    Best wooden wishes,
    Steevo.

    • Steve you had a musical spark generator in your older videos. This could be built with an automotive ignition coil driven from a 555 timer circuit that could be set up for burst to start the flare until it was switched over to run the engine.

      • CNCmacfun says:

        Howdee Mike,
        Indeed, a 555 timer is a good choice for a simple sparkler.
        I guess I am thinking along the lines of ‘super simple to build’, so anyone can make one with parts bought from their local auto-store.

        Seems to me that this wood be more popular than using a lighter or a torch?

        Best wishes,
        Steevo.

    • Joe Papa says:

      Steve, I think any useful information you can share will benefit someone who wants to incorporate a sparker into their build. I would like to add one at some point, but I guess I’m just focusing on items that are more of a necessity at this point. I will be looking for your video when I’m ready for it. Right now I’m gathering a bunch of parts. Hoping to get back to work very soon. I’m stuck making many many repairs on unexpected things. Look forward to seeing how you put it together. Joe

      • CNCmacfun says:

        Howdee Joe,
        Indeed, a sparker is a bit of a luxury, so it can afford to go to a lower spot in the priority list πŸ™‚ .
        Like you, I am up to my neck in work, so finding the time to work on any new projects is something of a challenge.
        That stated, I kinda like the idea of making a super simple sparker, as it wood knot take too long to build, and it wood be easy to maintain :).

        Best wishes,
        Steevo.

        There is no rest for the wicked, or us, for that matter.
        Currently building a house for my new/old excavator here.
        Tons of timber and drainage metal to the rescue πŸ™‚ .

      • CNCmacfun says:

        Howdee Luk,
        That’s perty sweet, but I am guessing it is powered by the mains?
        Ideally, this kind of thing wood be operable on 12V, so as to ensure that the whole system is independent of mains power.
        I don’t have mains power here, as the authorities have decided that I am not to be trusted with sharp and sparky things πŸ˜‰ .

        Best wishes,
        Steve.

      • luk vanhauwaert says:

        Steve, The one I use is indeed 220V, (a salvation one from an old oil burner). But a quick search on google tells me they come in all voltages, 6v – 12v, and there are even models that are powered by penlight batteries.

      • CNCmacfun says:

        Howdee Luk,

        That is good to know πŸ™‚ .
        Having always needed to build everything for myself, I tend to stick with that approach, instead of looking for off-the-shelf solutions.

        Those battery powered sparkers wood save a lot of lighters and gas bottles, I think.

        Best wishes,
        Steevo.

      • luk vanhauwaert says:

        Steve, you are a gifted man, wish I had your knowledge. But then again, having no knowledge at all, forces a man to think all new.

      • CNCmacfun says:

        Howdee Luk,
        Thanks kindly.
        I feel that ALL of us here are gifted, in one way or another.
        Our natural inclination to share our knowledge is watt makes this a truly special group of enthusiasts.
        Many folks keep their knowledge to themselves, and they lose so much by doing that.
        Here, we share everything, and we all benefit from it in the best possible way :).

        Best wishes,

      • Joe Papa says:

        Luk, I was wondering what you guys are up to with the drizzler? Do you still produce power and heat with it? I always look forward to seeing where you’re headed next. Keep us posted. We love videos. Joe

      • luk vanhauwaert says:

        Well, Prices to feed the grid have dropped immensely in Germany. Same time wood prices got up so it is no more economical for Pascal to run his system on daily base. I living in Poland and wanting after finished my new house, go up in off-grid mode, have not so much the need to make money. When I have some spare time in building my house, I am still amusing myself from time to time with woodgas. As a mater of fact I am just editing a video where I am experimenting to find a cheaper and less cumbersome replacement for the bag filter we use. Bag filters have the big disadvantage that you must heat up your bag filter house up above the dew point prior to filtering. Otherwise you destroy the bag. Hope to post the video today or the day’s to come.

      • Joe Papa says:

        Luk, I am looking forward to seeing your video. I have been very busy with a lot of things not gasifier related, but I have been collecting parts , and hope to be really producing power this fall. I mounted a hopper vibrator, added logic to turn it on and off, have all the components to connect the power I make to my house, and I’m in the process of acquiring more inverters and alternators to generate more watts. I’m hoping the additional load on the engine makes the gasifier run hotter keeping it up to temperature. I saw my hearth temps drop while under a light load. Should be fun. Thanks for the update. Joe.

      • CNCmacfun says:

        Sooooooper Simple Sparker Station.
        Hey guys, I built the design that was buzzering around in my head, and it works like a charm!
        Please feel free to take a looky here for an intro video on this:

        When I get me a few spare tick-tocks, I will make up a How-To video.
        This has got to be the simplest little sparker in the world πŸ™‚ .
        Woodgas bugz – – watch out!

    • Bill W. NH Hbbyloggr says:

      Oh yes, Count me in on this one. I’m running out of propane bottles and lighters.
      As a matter of fact , today I’m moving the entire wood bug clam along with their home to the Musterfield Farm Old Far Day show in N. Sutton, NH . I’ll put on a full blown run several times a day during the weekend event. Already I’m looking for that danged propane torch and lighter. Also hauling up the logging arch and side by side ATV for a log pulling demo. So yes, Steve I would be very interested in your sparkler ideas.

      • CNCmacfun says:

        Howdee Billyloggr,

        Yup, those pesky fire lighters have a nasty habit of vanishing, especially when it is time to fend off a woodgas bug invasion.
        As I see it, they are scared of woodgas bugz, and I really can’t blame them πŸ˜‰ .
        Wow – that show in Musterfield sounds like a lot of fun.
        It’s exactly the kind of show I wood like to get into, in order to spread the addiction, oops, hobby of wood to watts conversion.
        Yer gasser, and yer logging arch are gonna be a real hit out there, especially among the folks who have a hankering towards building their own ones πŸ™‚ .

        As for the sparkler idea, there seems to be two ways to go with it:
        1) An electronic one, with transistors and a silly-kin chip.
        2) One made from a pair of automotive relays, a spark coil, a capacitor and perhaps a ballast resistor.

        The first version will be very powerful, indeed sufficiently so to get the spark plug really hot – at 1000 sparks per second.
        The second version wood make 20 to 50 sparks per second, and will sound kinda like a buzzer.

        Both will light the flare, even if your lighter is hiding from woodgas bugz πŸ™‚ .

        Seems to me that the second option is better, as it ought to be super simple to build.
        Gonna collect me some bits, and give this a go – before I make any claims about its goodness as a buggy-gas-burner πŸ™‚ .

        Wish me luck πŸ˜‰ .

        Best wishes,
        Steevo.

    Anybody know what allgood automation has been up to. I just came across his videos, watched all of them and it seems like he disappeared from the planet. I was just curious because it seems like he corrected his issues and never ran it. Hope he’s ok. Joe

    • Bill W. NH Hbbyloggr says:

      Joe, As I recall there were several suggestions to help him along but there was never a reply from him. No idea if he pursued it further. Too bad, he was almost there.

    • Well you are right about dropping off from the planet because i kinda have. I have not yet fixed the major problem with my gassifier. The problem being the throat is to large 3.5 inches. I need to make it smaller and longer. The reason I have not worked on it is because I cant be around it when it smokes. A year ago January 17 months ago I was diagnosed with interstitial Lung Disease. I am pretty sure it has nothing to do with the gassifier. The Doc’s seem to think it is some kind of autoimmune disease, But they don’t know for sure. I have never smoked a day in my life. I now have lost 60% of my lung capacity and am on oxygen 24/7. I have a good friend that says he will help me do the modifications and testing and finish it up. Maybe this summer.
      In the last 5 months I have had over 20 doctors appointments and tests and have seen 9 different doctors. insurance has Spent 6 figures. I am just grateful just to still be here. In January of 2017 I went to the doc with what I thought was pneumonia and then was diagnosed. Crazy thing is my wife had the same crud at the same time and she got over it. I now have fibrosis and scarring in both lungs (permanent damage). Hope this helps and answers you questions. I would love to do more of this stuff but its extremely difficult for me to do any of this stuff any more. But I haven’t given up completely, I am working on some electronics projects for a medical device that i hope to market. Its a device to help people like me that has to be on O2 24/7.
      God Bless you all and I hope I never need to use that gassifier because the light’s have gone out for good. A EMP or the like. Thank for being interested and thank you all for your willingness to share your ideas and projects.I still enjoy watching this kind of stuff on YouTube.

      Thanks Again All.

      • Joseph Papa says:

        Thomas, I’m really sorry to hear about all of your health problems. I know that stuff can really get you down and keep you down. It was little over two years ago that I broke my ankle and didn’t know I had a clotting disorder . I had some internal bleeding with the break , and also developed a bunch of clots over the next month. I ended up with what they call a saddle pulmonary embolism. Both lungs were a mess for a long time.I still don’t feel like I fully recovered from it to this day, but like you said , am glad to have survived it. When you look up the symptoms for saddle pulmonary embolism, they include sudden death. What kind of symptom is that? Anyway , thanks for the response and I’m looking forward to seeing what you guys come up with . Remember , we love videos. I’m sure if you take care of those pesky air leaks, and get enough draw on the gasifier, even with the larger restriction , you will make good gas. Just don’t forget to start on biochar or royal oak hardwood lump charcoal. That stuff works like a champ. As for the plc, I know I chose a very expensive, hard to program platform for my project. There is a reason for it though. I work as a maintenance mechanic in a plant that has these plc’s all over the place. I felt like it would be a great training exercise for me to better understand my job and having an application to write my own logic, it gives me the motivation to get it done and I consider it home schooling . There are definitely cheaper ways to go about doing it, but I’ve enjoyed it so far. We all put our own twists on these things , but it’s better than reality shows watching the results of everyone’s ideas. Hopefully between everyone that is using these less expensive , easier to work with controllers, we can put together a how to series for anyone looking to duplicate all of this automation at as low a cost as possible. I know Bill aka hobbylogger is also working with arduino stuff. It should be great to see where all this goes. Hope things get better for you , and I’m looking forward to your progress. Joe Papa

      • Thomas I just wanted to say that I too am sorry for this ordeal you are having to endure and that my prayers are with you and yours sir.

      • Bill W. NH Hbbyloggr says:

        Thomas, We were thrilled to see a new face when you came on the scene . Sometimes we have to abandon what we love for reasons we don’t understand. I want you to know I thought you were right there on the doorstep to making a flare from the wood gas. Wish I was closer , I’d be real happy to get it going for you. I wish you success in your new direction and strength to deal with the afflictions. Keep in touch with our group and let us know how you are doing. Best Watts, Bill NH Hbbyloggr

  3. Joe Papa says:

    Hey guys, just thought I’d take a minute and post a link to the first run of the ninja on woodgas. As usual it had a few impatient bumpy spots, but over all I was happy to finally see this engine running on wood. I will be recording a clean out hopefully today showing what I find in the filters . Not sure if I will totally clean out the filters if I don’t see any tar, but I’ll keep you posted. https://youtu.be/GYNcdFYoAM0 Hope everyone is doing well. Joe

  4. Bill B says:

    Hey Flash, from what I have seen you do, you certainly have the skill to build a wood chipper. Just think of it as a paddle wheel. Each paddle has a bolted on blade. It’s really that simple. Start with two discs welded onto a one inch shaft. The discs have slits to hold the paddles and weld them in. The blades bolt on and get a little wider at the circumference of the disks, sort of shaped like a T, so that the edge of the disks are covered. The cutting edge is angled at a 45 degree. Have a magnet handy, then heat the blade till the magnet is not attracted to it, which is the time when it gets dropped in a can of water. Let it cool. Now it’s hard but needs to be tempered, which means taking it down a step in hardness so it’s not brittle. You do this by heating it again, but do not put the torch to the cutting edge, but rather start at the back, hold the torch in one place only and watch the color changes. The last color you will see is blue, and then just watch the blue travel to the cutting edge. As soon as it reaches the cutting edge drop it in the water and it is done. Then build a box from half inch steel, drill and tap, and bolt together. The top and bottom are open. Of course it needs holes for the bearings but you can work that out. Arrange it so the cutting blades are a hair away from one side. Drop the branches in and it’s chop chop time. First thing to do is figure out the ideal size for your fuel, then you can size the disks and how many paddles and blades you need. The space between the cutters is the length the fuel will be. The thickness of each branch is up to you, but make the depth a little more than is needed so it can handle everything that might be a little big. Maybe you can put a lean-to roof on the shed, and hang burlap bags filled with fuel to dry it out. To do any serious damage and truly make some real use of your gasifier you will be needing a lot of fuel, so at least start collecting it when ever you have a chance. I hope this helps.
    Regards, Bill B.

  5. Bill B says:

    Hey Flash, just had to write, since you stated that your next move is a chipper. Man did I ever find the perfect solution. This thing is very compact, very simple, very fast, very easy to build, very inexpensive, and highly portable.
    First I want to say that from everything I’ve seen concerning wood gas, I believe that the size of the fuel must meet the size of each particular gasifier, and this is a major point. Second, and also very important, each piece of fuel should be as close as possible in size to each other. I believe this combination, along with properly dry fuel is key, and will give the best results.
    Okay, this is on youtube. This subject line is long, 13 words, but just have the patience as it is so worth it. (amazing homemade wood chipper firewood processing machine, fastest wood processing chainsaw machines) This page has an assortment of chippers, but the one I want you to see starts at 5:20. You gotta love it.
    It looks like a pile of junk, thank god, these are the best, and of course it can be operated on woodgas. You can build it to put out any size chips you want, and feeding it branches that are approximately the same size would be a winning combination.
    As far as our last conversation, about the red flare, I know from experience that it can take years for wood to properly dry. I had suggested years ago that anyone that wants to build a gasifier should start collecting the fuel right away. I know by you it is very humid so perhaps you could build a chamber, lets say an old water heater tank, fill it with fuel, and run the engine exhaust into the bottom, cut off the top to let the moisture escape, and then close the lid after the run. Enjoy.

    Bill B.

    • Yeah I went and watched it. I like it and I already have a heavy duty kick-ass gearbox. Where would you find that kind of chipper at? I don’t have the kind of skills or tools to fabricate something like that from scratch.

      • Bill B says:

        Flash I do not know where to buy one, but first of all it needs to be determined what the correct size fuel is. If each piece of fuel is to be 1/2 inch long, then the space between each cutting edge needs to be spaced at 1/2 inch. For 3 inch long pieces a larger diameter cutter is needed and each cutter would be spaced at 3 inches. The depth of space between any cutter blades could be made to be a little deeper than would ever be needed.

        Now, fuel size is important, but to find just the right size branches would be a monumental task, so for that sake you could determine the approximate size/range for each gasifier and just go with that. But uniform is best for even heat.

        If one really wanted exact size, 3, 4, or 5inch logs could be cut to lets say six inches long, and fed through a mini log splitter, splitting them into sticks. This ought to make them very close in size.

        There are several ways to make the cutter and one is to have the local machine shop mill one from a solid billet, and another is to weld pieces of heavy duty angle iron to a 1inch diameter shaft. Each piece of angle iron would be cut to look like an L. The short side gets welded to the shaft.

        The machine shop way may be a bit expensive, but even so, consider the years of service you will get from it. Lets face it, even with the best gasifier in the world fuel will always be needed.

        I want to say a little about having a system. I have heated my house with wood for 41 years. Most people buy a pile of wood just before the heating season and they struggle with it. When I burn, I am burning wood that was split and stacked three years prior. Just before the heating season I cover the wood to be used with a plastic tarp. I use three cords a season. The heat generated and the efficiency achieved is the best one could ever have. A system also makes it easier. Once set up, you don’t use good hours on a Saturday morning to split wood, but rather dead time is used. These times are times when you know you can’t do anything else, like go out, because dinner will be ready in 15 minutes, so spend those 15 minutes working on the wood, or lets say your evening shower is 30 minutes way. Once you have a system set up you can do things like that. It’s just so much easier with a system.

        So now that you have come this far with your gasifier, take it to the next logical stage to keep it running without breaking your back.

        After seeing all the super fabricating you have done I thought for sure this would be a cinch for you to build. But I do get the feeling somehow that you are pressed for time. So just think of all the time you will save in the future, so make your plans for the build and eventually over time you will have it. Really it’s just cutting and welding on a small project.

        I also think that right now, fuel is your problem, considering that red flame after the filter. So think about it. It actually took me years to realize I’m killing myself and that I need a system. I suppose it actually comes down to organizing. This way you could always keep the batteries charged, and from there expand it to power the house too.

        Regards,
        Bill B.

  6. Bill B says:

    Question for Flash. I viewed the 3/31/18 vid, and just before you started the gen you had the flare going down by the gen, which must have come from the filters because you pulled the gas hose from the flare and put it right to the gen and started it right up. Why was the flame red instead of blue?

    • That’s a good question because normally I will see a blueish white flare or even a white flare and at times a faint reddish flare. I’ve been seeing red and orange flares from the filtered side for quite a few runs now. The main thing I’m looking for once the gas is filtered is for ANY fog or faint smoke coming from the flare port before I light it up. If I see any fog or smoke I will not run the engine until I determine if what I’m seeing is tar in the gas or just steam vapor from the heat passing through the filters that could have been caused from residual water dampness from the washed filter media evaporating into the gas. Tar will almost always burn yellow and a purple flare is from a semi-clean gas that contains a tiny bit of tar in the mix. To answer your question before I ignited the flare the gas was invisible so the only thing I can think of is maybe trace minerals or other things other than tar being passed along with the woodgas. If in doubt the correct way to test the gas is to lay a cloth over the flare port for about 10 or 15 seconds and if the stain washes out you are OK but if it stains the cloth you have a tar issue. I didn’t even have the need to do a cloth test because the gas from my filtered side is invisible.

  7. Bill B says:

    Hey Flash, seen your automated system. Man that must give you a thrill and a boost every time that bugger kicks in. Good job, congrats.

      John, welcome to woodgasaholics anonymous. The first step is admitting you have a problem being held captive by oil and power companies. From there we slowly work toward getting out from under their thumbs. You’ll find plenty of people here, with all different specialties, willing to offer help however we can. Most of us have already been through the challenges that you will be encountering, and share what works well, and what has limited success. This is all open source with the goal of getting as many people on the road to energy independence or whatever your intentions are with gasification. It is a subject worth investing in, and a design worth building . I have some of the cad drawings on my home computer. I will try to send them your way later today. my YouTube name is mazdalorean. Welcome to woodgas, and be sure to post videos of your progress and share the links with us here. We love videos. Keep us posted on your progress. Joe Papa

        Bill, it’s like job security. Every time something fails , your family is always happy they have someone around that can take care of the problem for a fraction of the cost of someone that knows what their doing. As for the filter material questions, I’ll let you guys field the question. You all have much more experience with different filter materials. Thanks for the laugh. Joe

    • Bill W. NH Hbbyloggr says:

      John, As far as filtering material found in the wild, dry straw, dry wood chips, shavings work as long as they are not tightly packed. Also, I have two pre-filters which use 3/8 Pea Stone. They really grab hold of particulate and further cools the gas, trapping moisture as the gas is pulled through. I’m probably going to change from the more round type pea stone to a more angular screened crushed stone.
      Be sure to wash the fines out of the stones before you use them. You can get a ready supply of stone from any gravely creek, brook or river. Totally renewable and washable. I keep three full batches , washed dried and ready for easy change outs. Stainless steel scrubbers top and bottom of the filters keep the stones in place.
      BTW Steve T in NZ also uses this filtering method.
      Hope this helps. I have a couple videos on them on YT at” NH Hbbyloggr” channel.
      Let me know if you need more detail
      Bill — NH Hbbyloggr

      • John Yurgel says:

        Bill, I did see your pea stone vid. Are you switching because of flow restriction?
        I wonder how lava rock would work very porous and lite but it’s not readily available at the creek in Pa. though.

      • Bill W. NH Hbbyloggr says:

        John. 3/8 round peastone tend to pack a little to tightly. I’m going to try 1/2 crushed quartz. More angular and will allow better flow I think. The experimenting, It never ends. I had another run this morning and will probably fire it up tomorrow too. I just like doing it even if there isn’t a reason.
        Now, Matt , over at Thrive Energy systems doesn’t use any filter media. Just a series of cyclones. He even says they don’t need to be ” conical “, just cylinders. I have a bunch of 4” metal conduit piping which I used for the P Stoners and may set up a rack of those hollow cyclones to see how it does. He is pretty successful and way ahead of us, so he might be on to something. That said, he does have one paper filter installed just before entering the engine. If that gets contaminated it shuts the engine down immediately. Makes sense to me.
        The more ideas and tales of success or failure you add to your tool box the better you will be able to work with these little flowers.
        What do you plan on running, Generators? alternators? charging battery banks, or keeping the coffee hot?

        Bill, There’s no reply button after your other comment so I’m replying here.
        I’m going to start out just running my small generator for outages and use that to “cut my teeth” on.
        I do one day hope to have a working farmstead and run the whole thing with wood gas including vehicles.
        Does anyone know why some comments don’t have reply buttons and are we missing a step?

      • Bill W. NH Hbbyloggr says:

        John,
        I suspect leaving a return reply has to stay within the original thread. Not sure but Mike ( Flash) is the moderator and he would be the one to ask. If you want to get in touch with me, email is hbbyloggr@grolen.com . I’ll include you in our regular shared discussions. There are a few of us who chat quite regularly. I’d say we are family in my book.
        You are starting out like I did. Just want a back up source of power not depended upon the grid. The ice storm several years ago which shut down New England for a couple weeks was the inspiration for me. I’ve been working on this gasifier ever since and have had a great time with it, met the best people in the world and I’m grateful for taking this path. Bill- NH Hbbyloggr

      • John I’m not sure why they set it up like this but if you leave a reply or a remark we all get the messages and we can actually see who is talking to who. It’s kind of like a digital party line.

  10. Jack Ruska says:

    Hey Mark, would it be possible to get a copy of the PDF files also. I have been taking notes and making rough sketches of your build. I can use all the help I can get and it would be greatly appreciated. I am not going to start my build until after the holidays. Gathering materials, now and getting ready. Thanks for all your video’s. They are a great inspiration. I have been bitten by the bug, and can;t wait to get started. Thanks. Jack ( Tater Tot) nrmracing@yahoo.com

    • Joe Papa says:

      Jack, I sent a copy of the cad drawings to your email address. If I sent it right you will also now have my email address. Any questions just ask. Joe

      • Jack Ruska says:

        Hey Joe, Thanks so much for the PDF drawings. They are so much easier to read than my sketches I made from viewing Mikes videos. I have one question. On a later video, Mike was talking about the extension tube modification. He suggested a straight tube about 3 inches long.. And on one of your videos, I believe you made a modification to an extended tube. Would you like to elaborate on that and what benefits it had. Thanks and really appreciated the quick response to my request.

        Jack (Tator Tot)

      • Joe Papa says:

        Jack, the modification was Mikes idea. Originally it was just a straight tube with a 3″ id. about 3″ long. Mike thought it would be better if the tube was a little bit longer, but didn’t want to keep it a straight tube , so it is a slight inverted bell. Here is a link to one of my videos that show a series of pics showing the build of this part. Now this was my interpretation of the part. I machined a solid piece of round steel down so the 3″ opening at the bottom of the hearth had more of a funnel to it rather than a plate that reduced the the 3″ diameter hole to about 2 and 1/4″ at the top and 2 and 1/2″ at the bottom about 5″ tall. The idea was to not make it difficult for the char to make its way to the ash grate by making the reduction zone open up slightly as the char moves downward. The extra 2 ” in length add to the amount of filtering that can be done by the char to make the gas cleaner . Here is the link and sorry for the crappy quality. these pictures were taken on an old phone and I couldn’t get them any clearer. https://youtu.be/ZFDNzRl2XZ0 . Just skip to 7:45 and it will take you to a drawing that I made of the side profile of the part. Hope this helps. Joe

      • Jack Ruska says:

        Thanks again Joe. I will definitely double check any charts and info I can find before I fabricate the size of the cone to make sure it will work with my generator. From what I read so far a 420 cc 16 hp should work with the 5-inch cone. I will keep searching to verify before I build. On another note searching thru the older comments, I figured out what happened to Flash. WOW! Flash I hope you are healing and getting back to your old self. Wish I lived closer maybe I could help out in some way. We don’t have much but Franklin County VA is the moonshine capital of the South. Maybe a little MaMas recipe might ease the pain. Get well my friend, our prayers are with you and your family.

      • Joe Papa says:

        Jack, the hearth dimensions don’t change. It is 5″ at the top and funnels down to 3″ at the bottom as per the cad drawings. The part that bolts on the bottom of the hearth is what we refer to as the reduction zone. It almost resembles an upside down top hat. Hope this makes sense. I think you might be ok with the 2 1/4″ at the top and 2 1/2 at the bottom dimensions I told you about earlier. Maybe someone else can verify the approximate reduction extension for a 16 hp engine.

    • Mark Adams says:

      Hey Jack. Mark here. I see that Joe sent you the drawings and they helped out out with your understanding of the system. I also have a pile of cutaway views of every part of the system if you think they would be of help. I am not sure if Joe had the filter drawing as of yet. I sent them to Mike to add to the PDF file. Let me know if the filter build was included. Any questions you may have, or if you would like pictures of my build, feel free to contact me at mada94fxr@gmail.com and I will be happy to help you with what ever questions you may have. The main thing is to take your time with the build and make sure it’s air tight. Each or our builds are slightly different than the Flashifier. Mine is the closest to Mike’s original build almost to the tee, including the 3″ dia. x 3″ long straight extension. I have 4 different engines I have run on the system so far, with different HP and all have run just fine to this point. I just replaced the engine on my DC generator from a 9 HP Briggs to a 16 HP single cylinder Kohler. I haven’t tried it on bug juice yet. But I will be doing that soon.
      Mark

      • Jack Ruska says:

        Hey there Mark, Thank you for your reply.
        Joe was kind enough to send to me the 4 page PDF file on the trailer hub fabrication. Which really helped. I would appreciate any information on the rest of the build you would be willing to share. I have been compiling my own notes and sketches from the Flash videos. Any sketches or additional PDF files would be more than welcome. Thanks again

  11. Bill W. NH Hbbyloggr says:

    Yesterday’s news today: Embellished, of course.
    Steve D , a nuclear scientist, high temp expert entrepreneur and prepper ! stopped by to see a NH Flower performance. He is a real down to earth guy as I’ve mentioned, hands on, and very interested in the alternative energy sources. I had the gasifier cleaned right out, no char or wood in it , the nozzle removed for him to see up close to show the oxidation effects .
    First thing he does is dig into the 5 gal pail of char with both hands to feel what the texture is like of those little carbon nubbers. Yup, he is now a member of β€œ Black Hands Matter β€œ group , the anti-energy establishment movement not at this time sweeping the country.
    One of the most telling expressions on his face was when I snapped the LFD to life. Here is this scientist, over the top knowledge guy, with the biggest twisted grin I’ve ever seen. I mean, this was a grin usually only seen on 10 year olds when they have been told what to watch for but then to actually see it with their own eyes, was a moment in time for me. Ahhh, the first nip of the bug bite.
    The flares, the effects on the flares as the grate and vibrator added their timed input, were all recognized by him. Even as the LFD was running, he was over at the air/gas mixer flash carb twisting the adjuster back and forth , evaluating the effects just a slight twerk makes for optimum performance. . I mean, this guy was picking it all up, almost giggling over the effect he was having on the little LFD Honda.
    He says that we all have something here to be very proud of here.
    It was then that I realized that I had not turned on the cameras. A couple of hours had passed rather quickly and we all had other things to do for the rest of the day…at least he did. There was still wood in the hopper when I shut it down and he went along on his merry way , skipping down our old dirt road with butterflies following along. He was last seen rounding the corner, whistling and singing to his flighty little followers.
    For me, a firm believer in never leaving a good piece of wood un-burned, I opened the air nozzle , turned on the blower and restarted the process…with the camera turned on this time. I have in my array of diagnostic tools, normally just a big hammer and garden hose, a laser guided infrared temperature gun and like with a new toy at Christmas , took readings of the barrel, rad tubes, Expansion tanks, P-Stoners final filters, LFD exhaust pipe, a mouse running along an overhead cable( who was not impressed having a laser beam tracking him) , and, back to business, the internal temp of the wood . Surprisingly the wood temp at the top was 211*F. The mouse escaped .Ha !
    This was by far a great day for this NH Hbbyloggr and a real morale booster for the little wood gas buggers who have been so patient.

    At this time I would like to introduce Steve to our group of enthusiasts. His knowledge of high temperature materials , real time measurement instrumentation , would be helpful to all of us. His immediate interest is in building a gasifier using coal as a fuel source. Any input from our fellow gasoholics would be welcomed.
    All the best watts,
    Bill

    • Joe Papa says:

      Welcome Steve D, I think you’ll find that there are no shortage of people willing to answer questions and give lots of useful advice. The prints that are floating around are very thorough and should be pretty straight forward to follow. You will find that this is a solid design and gives great performance compared to lots of other designs out there. Mike hit a grand slam with this build and I can’t wait to get to the point of real power production. Feel free to ask any questions you may have. Joe Papa AKA Mazdalorean

      • Joe Papa says:

        Tim, it’s nice to see schools working with gasfication. The all power labs guys have some great videos on the science of gasification. Im not sure if you’ve seen them , but they do a great job of explaining what is really happening iside the gasifier. Joe

      • Bill Weigle says:

        Tim, Thanks for the read. One of my wood customers, a professor at a community college, took an interest in our gasifier and submitted a proposal as a senior project to help build an air/fuel mixture control to any students interested .
        Unfortunately there were no takers this time around. Too bad, a missed opportunity for some student who might have discovered a new path.
        At least the idea was presented and some young thinker might have been nipped just enough to look in our direction. You never know.

    hello everyone, im getting into this gasifier building , i jumped in and just threw one together before i knew anything about them, yep you guessed it, it doesnt work , so after finding out about flash001usa on youtube, ive opted to start all over and build me a flashafier, and thanks mike for all the information to build my own, if i can get it figured out , i would like to do the same as you and pay it foward and help someone else, mark-tennessee

    • What’s up Mark, Flash here (Mike here) If you have any questions there are enough of us to help you out with any questions. If you have not started on the new build yet hold off. I just did a updated build that may be simpler but I won’t be able to test it and upload a video for at least a week due to going out of state but I will test it and upload a video as soon as I return.

Just let me know

  13. Joe Papa says:

    Hey guys, just thought I’d let everyone know I did some more testing on the ninja and the electrical system. For some reason , notifications were not sent out, so here is the link if you want to see the progress. https://youtu.be/7bplTdCwXsM
    I still have a few bugs to work out, but it’s finally making power on demand. I will continue to test on propane till I get things all squared away, then I will be able to fire up the gasifier and run on wood. I’m looking for suggestions on why I’m only seeing about half of the rated power output from my inverters. Bill did leave his feedback and I will try his idea when I get a chance. Later. Joe

  14. Pete Rosenkrans says:

    In answer to all the talk I’ve missed…. I use biochar mix, and burn up a fair amount of plastic, too.
    I just started a methanol cow to see what the output is…..been wanting a still, but haven’t had time.
    Keep in touch,my fellow gassers.
    Pete

    • Bill Weigle says:

      Hey Pete,
      Question for you about the plastic. Do you chop it up small? and what do you figure the ratio is to the wood ? Do the still , Man ! Just Do it !

      • Pete Rosenkrans says:

        I run it thru a cheapo wood mulcher, I also just save all small bottle lids and they go in like that… I go about a20 to 1 ratio- works pretty good. depending how hard you’re pulling on it. As for the still….OK, I pretty much accidentally got most of what I need. I see some possibilities!

      • Pete Rosenkrans says:

        I actually have a pretty decent phone ( camera) now too. I was thinking this fall?

  15. Joe Papa says:

    I have a question for everyone. What are your thoughts on adding some biochar to your gasifier fuel? I’m thinking you can change volatiles to fixed carbon ratio from 80/20 to more of a 50/50 ratio allowing more carbon to be available for the reduction reactions. I think there are more advantages than just the ratos. You can lower the pyrolysis load on the combustion zone by diluting the amount of raw fuel passing into the combustion zone. Plus everyone talks about having leftover usable biochar, and it can be a good way of getting the rest of the energy out of the biochar. I just thought it would be interesting to hear what everyone’s thoughts are on the subject. Joe

    • CNCmacfun says:

      Howdee Joe,
      Yes, I think you’ll find that this idea works quite well.
      Bill does it, and I seem to remember that he gets good results from it, while also getting rid of all that leftover chark-o-cola πŸ™‚ .

      Best wishes,
      Steve.

    • Bill Weigle says:

      Joe,
      I’ve been doing that for awhile now. I do save some for starter char , screen the fines out from the accumulated char collected in the bottom of the barrel. Most of the salvaged char gets mixed back in with the wood chips at about 5:1 , The fines go into the garden or sometimes get tracked into the house.
      I also just started snipping little pieces of plastic and adding that in to the mix. Jury is still out on that one.

      • Bill it’s strange to hear you mention plastic as an additive because years ago when I started this I talked to this guy that like “down under” Steve lived totally off grid and he used to swear by it. He used old plastic coke bottles and chopped them up into tiny pieces. He said that way it wouldn’t turn to melted goo and clog things up. I’ve never tried it but I do see where biochar would work. I’ve tried biochar but I couldn’t tell you how well it works since it’s been a long time. I’ve also trued pure biochar during a run and yeah it produced gas but it isn’t efficient with our types of gasifiers so you really need to build a gasifier that is designed just for biochar. but that’s another story for another time.

      • CNCmacfun says:

        Yeah, that Steve guy from down under is a bit of a strange booger.
        He chases camels around the farm with his infernal flying machines, while living off grid like some sort of weird hippie πŸ˜‰ .
        Yup, plastic bits, mixed in with the treezel bits, works like a charm, and it certainly does add a noticeable degree of watty oomph to the volty goodness coming from the generator.
        I wood suggest that you don’t add more than about 5% by volume of plastic to the wood, so as to ensure that your charcoal bed doesn’t lose its integrity during a run.
        Mine eats a lot of plastic during the year, and it is none the worse for wear, other than getting kinda old and worn out πŸ™‚ .

      • Bill Weigle says:

        Hey Mike, How’s the arm doing? Yeah, I’m in pretty close touch with the wildly talented Steve from down under and all the trials he’s had. I think he said he runs 20:1 wood to plastic when he has it from the CNC turnings.
        I have noticed the flare goes from blue to red-orange when the bits hit the jack pot. I’ll try it out on the Left For Dead Honda by and by. Hope everyone is well !
        Bill NH Hbbyloggr

      • Bill the guy I used to talk to when I got into this went by the youtube name technofreak and he said it gave the gas some more punch but like anything else I would have to tinker with it to get an idea if and how much it contributed to the engine performance. As to the arm I’m just glad it’s still attached to me. It’s still sore and I can only get temporary range in it because once I rest it, it gets tight. Only the shadow knows how long it will be before I get free movement back in it.

      • Pete Rosenkrans says:

        Mike, sounds like you’re on the right track, you know those surgeons can be a little rough, I’ve watched videos of surgeries that make me cry…. try the Knox, it’s got no flavor, just the consistency that can be” hard to swallow”…. it really turned me around, but I was just sore- nothing like your situation, but what can it hurt, and it’s cheap. I use them all, I, too, am a ” health nut” and like natural medicines over pharmaceutical stuff. even the Bible tells us to avoid pharmacist, but anyway, keep moving, I hope things improve.

      • Pete Rosenkrans says:

        Mike- do not go for the pies! We have all kinds here and while they might work in the gasifier, they’re still turds if ya eat them. I switched shifts and jobs and I was hurting, every tendon, ligament and muscle.knox did wonders for me. Also try glucosamine chondroitin- that also helps your joints.
        Good luck I hope ya find some relief!!
        Pete

      • Pete I started taking glucosamine chondroitin again this week. I’m not sure if this is tendons or what. The only thing I can think is when they had my arm cut open they probably pulled the bone they were putting back together out enough to reattach the broken pieces so my thinking is they stretched things in ways that they would not normally get stretched plus I did have a muscle that was ripped in half that they put back together. Dude this has sucked but all I can do is continue to work out and hope for the best.

    Just thought I’d share the link to a short update. The are a lot of details that I would have liked to put in this video, but I know it would take a couple of weeks till I get the time to get the editing done. So this is more of a teaser video right now. https://youtu.be/Y-deFXS5vcs

  18. Hi Guys,
    Thanks for the quick response! I have started to construct the hearth and wanted to make sure the fire cone dimension were capable of supporting a 20HP (12KW) generator. I found a sweet deal on a slightly used generator that was hard to pass up! I do see in Flash’s videos that he is using a 5 HP engine and his design should support up to a 15HP generator. He mentions increasing the size of the air intake nozzle (1/2” to ¾”) and the reduction zone cone for the size of engine that you plan to run. Any recommendations on the reduction zone cone would be greatly appreciated. I know there is a chart for the sizing of the FEMA burn tub to engine size, does such a chart exist for the Imbert style gasifier?

    I also did not see the thickness of steel used to make the reduction zone cone called out. I assume it is 1/8”.
    Al

    • Hi Allen Flash (Mike) here. When I built this design a lot of it was trial and error and The true upper end of the gasifier may be closer to 12.5 Hp. Bill (NH Hbbyloggr) has tested larger engines so you may want to pick his brain too. I’ll be more than glad to give you as much feedback as I can if you need it. Good luck with the build.

  19. Al Fraser says:

    Hello Everyone, first off I wanted to thank Flash for building this web site. I know that making all the videos and compiling all this information on wood gasification and no easy task. I would also like to thank all the other Wood Gaser for contributing and sharing their knowledge. I have watched all the videos at least once and read through the blog. This was very educational, thanks again! I have heard mention of a PDF file of drawing of the Flashifier. Would it be possible to get a copy of this file? If possible could someone email it to me at afraser@metrocast.net. I have started to gather the materials needed to build a Flashifier and think these drawings would aid in the process.
    Hi Bill, I live in central New Hampshire and would love to pay you a visit and see your gasifier. Please let me know if that would be possible. Al

    • Bill Weigle says:

      Hi Al, and welcome. We have all had good success with Flash001USA’s basic design. Everyone building one of these has modified their rig to suit their needs and have lived to tell about it here on the Blog. There are a couple of other builders with different designs but as we know ” all roads lead to Rome “.
      At the moment my gasifier is apart being modified , though all the components are here waiting their turn for restoration. You are more than welcome to come have a look, share your story and I’m sure we can be of help if you need it. I’m hoping to be back together in a month but there are forces out there competing for my time. That said, all I have to do is weld on one pipe and I can stitch it all back together to demonstrate a run for you. I would be happy to do that. Where in the Granite State do you live? Send me your Email address to hbbyloggr@gmail.com and I’ll tell you our address. Basically we are 20 miles west of Manchester. Even if it is not running there is plenty to show to help you get started.
      Give me a heads up in a week or so and I’ll make sure it is operational for you.–Bill NH Hbbyloggr

    Hi Everyone,
    So I’ve been buried with work and spring tasks at my lot so I had shelved starting my gassifier until the fall.
    Completely unrelated to woodgas I was looking into a still for making …. water. I stumbled across an article about distilling methanol from wood. Where I am distilling fuel is legal.
    I started thinking about switching my power focus from a gassifier to a methanol plant. Then instead of having to startup the gassifier every day to charge my batteries I could run the methanol plant periodcaly (monthly maybe) and build up a reserve to run the generator. Then the generator could even be started automatically when needed even when I am not there, something that is not possible with a gassifier.

    Another added benefit is for methanol production the smaller the wood pieces the better so running on wood chips is ideal. This means wood production should be easier given my potential fuel source (logging slash piles)

    Has anyone else looked into creating methanol for running their generator on? Would love some feedback even if its that you think I’m crazy.
    Thanks

    • Joe Papa says:

      You could check out the all power labs videos. I do believe they are doing some research on gas to liquid fuel. Here is the link . https://youtu.be/KFtrhz47K3Y I’m not sure if this is what you are referring to , but I knew I saw this so I thought I’d share it. Joe

    • Mark says:

      I have all the parts and pieces to make a still as well for making………water………
      Actually, I have 16 big batteries on my solar system that need it and had thought about making hooch to see how it works in one of my spare engines. I know that during prohibition, the moonshiners would run the hooch in their tanks for a boost to outrun the Feds that were chasing them. That is also where NASCAR kind of got it’s start. Think Junior Johnson. But in today’s engines with the rubber parts in the carbs and the valve material ( think unleaded fuel compared to leaded), it may be a problem. But, if you are planning on having solar out at your place, a still is not a bad thing to have for your battery bank. Beats buying distilled water.

        Mike, sounds like you’re on the right track, you know those surgeons can be a little rough, I’ve watched videos of surgeries that make me cry…. try the Knox, it’s got no flavor, just the consistency that can be” hard to swallow”…. it really turned me around, but I was just sore- nothing like your situation, but what can it hurt, and it’s cheap. I use them all, I, too, am a ” health nut” and like natural medicines over pharmaceutical stuff. even the Bible tells us to avoid pharmakia, but anyway, keep moving, I hope things improve.

        Marvel mystery oil mixed into hooch, or gasoline, will lubricate those plastic and rubber pieces, helping to keep your engine from the deteriorating effects of” strong gas”
