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

    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.

      • 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

    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 “ Black Hands Matter “ 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,

    • 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

    • CNCmacfun says:

      Howdee Bill,

      Ahhhh, I love your colourful use of the mother tongue here 🙂 .
      As the computer read it to me, I chuckled, lotsly, and almost suffered a keyboard sized coffee tsunami 😉 .
      Luckily, I was testing a sample of Mr Trump’s new wall at the time, and it successfully held back the flow of caffeine enhanced goodness for long enough that I could suck it up with an extra absorbent woodgas bug 🙂 .
      Here’s hoping your newest bugbite victim will become hopelessly addicted to the goodness of woodgas power in the very near future.
      You sure are hooking lots of new victims, and you are duly making your woodgas bug slave drivers very happy indeed 🙂 .

      Best wishes, oh addicted one,

      • 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.

  4. mark mcneal says:

    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

    • Bill Weigle says:

      Welcome ! Good choice with the Flash001USA gasifier. I’ve got a couple hundred hours on the one I built using his design and never stop learning as we go.
      Good luck to you and give a shout if we can help. Bill W.
      NH Hbbyloggr

    • Joe Papa says:

      Welcome Mark , I’m with Bill saying if you have any questions, just ask away. You shold be smooth sailing with a copy of the prints on auto cad . If you don’t have them yet let us know. Mark from Florida drew up some nice plans for us all. Makes the build much easier. Joe Papa a.k.a. mazdalorean.

    • 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.

    • Mark Adams says:

      Hey there Mark from TN. This is Mark from FL. Welcome to the group. If you would like the PDF CAD drawings and instructions, post your e-mail address and I will be glad to send them to you. Mike should have his new build done very soon. But, I also have a pile of other CAD drawings that I can send you for different components like the filters, controls for auto shake and vibrate. Just let me know

  5. 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

  6. 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.

    • 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?

  7. 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 🙂 .

      Best wishes,

    • Bill Weigle says:

      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 😉 .
        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 🙂 .

      • 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:

        Flash, try putting Knox gelatin in 1/2 cup water let it set out till it turns to gelatin, then gag that down your hatch for a month- ya read up on it, the stuff can do your joints slot of good. I’m not a doctor, but I play one all the time, check it out.

      • Pete Rosenkrans says:

        It’s really just a lot worse than lumpy malt o meal, but man does it work. There’s also turmeric curcumin, or cinnamon, both In the vitamin aisle, true cinnamon has a lot of good properties, once again- I am not a doctor, but I do offer free medical exam’s to pretty girls, I do not get a lot of willing ladies, unfortunately.
        Oh well, it’s a numbers game.

      • Bill Weigle says:

        Pete, No girls are interested in medical doctors, but hang out a shingle saying you are a recovering woodgas voodoo doctor of questionable moral character and you will have to buy a reservation book…..maybe even start a lotto. They can call me for references if you need me.

      • 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 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.

    The day begins with soft cello music in the background, the sun about to peek through the trees. The predawn breeze shimmers the leaves as the music builds intensity.
    It is the day we have all been waiting. A new dawn, a new bug bitten wood gas victim is about to wander into the shop as a willing subject, soon to become a convert, one of the chosen few to unlock the secrets of the sweet wood tea.
    He shall have is pockets filled with precious chunks of Butt Cut puzzle pieces upon his initiation. His palms pushed into the puddle of post gasification wood tea. He will smell his fingers with pride, knowing the release of pure energy was good, magical and he now shares the power to turn the key to unlock the chest filled with volts and watts. Amps be unto you who believe. Before you lies the freedom from the grid. Now go forth and set forth a flurry of hatchet swings, chunk wood and bring peace to your soul.

    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

  10. 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”.

    • 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.

  11. 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

    • Mark says:

      Hey there Al and welcome. Bill contacted me and told me of a new victim on mimiwoodgas. I will send you the PDF files later this afternoon after I get finished with my dirty deeds for the day. I will send them in 3 to 4 e-mails as there are like 12 separate pages. If you have any questions, please feel free to contact me.

    • Joe Papa says:

      Welcome Al. I think between Flash’s videos and the pdf’s and a little time reviewing the details, it will all be very clear. If you do have any trouble, all of us will offer help. Just remember we like pictures and videos so keep us posted. Let us know if you need anything. Joe

  12. Unique3 says:

    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.

    • 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.
