Having used to formally being a young contractor, your patience explaing details was much appreciated...your attention to detail was refreshing....will definitely subscribe....
I see Mr white as one of my teacher in High school. his explanation are so clear and easy to learn from. Than you Jim White. It has been a pleasure to see your videos.
As a tireless searcher for tutorials, videos and all kinds of possible information to do things in my workshop, I think I had not even imagined running into someone in your category to learn how to do something that has made me go through dozens of people who know little or nothing, and at the same time having built (thanks to their instructions) devices that fulfill almost none of their purposes. This video is a master class on how to do something well done and that has no other intention than simply teaching so that everyone learns, instead of being a method to sell us something. I'm sorry to say this, but the internet is full of charlatans who spend their time telling us lies. Thank you very much Jim for your dedication and effort in teaching us. I am in the glory and my hands are itching to go to my workshop to follow your instructions and build your foam generator. Blessings to you
Hello Jim, great to hear from you. On the other hand, and if you don't mind me bothering you, I would like to be able to consult you if something is not going so well with my design of your design. It is very important for me not to fail with this. Thank you and greetings from Chile
@@Jimscoolstuff Thank you Jim, your support and help is greatly appreciated. I will write to you as soon as I have something important to tell you or consult you about this charming project. With love, Alien
Thank you for taking the time to give detailed build instructions and parts info. As an amateur video producer, I really appreciate the effort it takes to re-capture all this info.
Thanks for sharing your knowledge. I attempted to scale up your idea and struggled with numerous leaks because the PVC was just too soft to really tighten anything enough to withstand the required psi to make the foam. After 6-9 months of experimenting, I have created a foam generator using a portable air tank purchased from harbor freight. I now have minimal leaks and am producing fun aircrete projects. Thanks again.
Thank you so much for explaining how you made this. After watching many foam generator videos yours I love the most. It looks like it wips the best. I'm going to mimic I'll post a video asap.
Hey Jim, love your wand and generator system, but could you provide a written partslist, and maybe an assemble video of the generator, already have the wand finished, thanks a lot for all your videos, great content.
Thanks so much for all the information. I've been having trouble controlling the pressure inside the liquid reservoir and obtaining the correct density of foam to create both foam and AirCrete that do not collapse. I had been wondering about placing a pressure regulator inline somewhere, either between air compressor and reservoir or between the reservoir and the foam wand. Your setup is much easier to use than the one my husband and I are using, and after he watches your video, I suspect we will be making some adaptations to our system!
Lots of work and time invested in sharing with others.. I just want to say for myself and many others out here on RUclips.. Thank you much Sir.. Mr. Jim.. This is what makes sites like this so valuable.. I started putting up videos myself of things I don't find on youtube, not caring to monitize, but, to just say thanks myself and to give something back that I have gained so much from... When I saw the foam mixed with the portland, it was obvious it was not going to be "As" Strong, but, a medium to use for other things "Lightweight, Insulative, etc... It has it's distinct advantages.. I'm going to use it and do some testing as a light weight refractory mix to make a Rocket Stove Mass Heater without so much mass, and play with it and see if it can be used for the bulk in a furnace, with a top coating of something else mixed in or put over it.. I like your foam gun.. Simple, and effective.. Already thinking of how I can make one with what I have on hand.. Going to be digging in the parts bins to see if I can make something without the 45 minute trip to town.. :).. Have a great day Mr Jim.. Cheers!
Thanks for the video. Should help a lot of folks understand things better. I realize you are doing small scale experiments, but if you decide to go bigger, consider using an old air compressor tank for holding your foaming solution. They are already rated for pressure and you could hold more gallons of solution before needing to refill.
Hi brave guy and thank you very much for this adorable sharing!! Please tell me have you made a video where you teach us how to build this excellent tool, thank you very much for showing me the link
This video and the two videos listed in the description show enough information to build a similar foam generator. Thank you for your comment and best regards.
@@Jimscoolstuff Thanks and gratitude are extended to you, my dear sir... You are the one who cordially shares your beautiful ideas with us... I am trying to make a generator similar to yours, but larger in size. I hope to find your support and assistance
I'm thinking that because the foam solution reservoir pipe is already under pressure, the eductor isn't needed. It would seem your needle valve is all that is required to control the flow of foaming agent to the wand. Or am I missing something here? Edit 12/30/20 I'm almost done building a variation of your foam generator. I'm going to use a 1/4 inch three-way barbed nylon connector in lieu of your eductor and see how it goes. I'm also outfitting it with a small brass valve I found in the air compressor supply section at Menard's for the fluid control. It has a slightly larger diameter and I'm hoping that it, in combination with the increased air flow from omitting the eductor, will be able to produce foam at a faster rate.
@@renesausa737 I did build the device without an eductor. The nylon Tee fitting I used instead of the brass compression fittings seems to work well and provides a much larger aperture for air flow. Unfortunately, my compact air compressor cannot provide enough air to take advantage of it. With a larger air flow, I suspect I'd be producing copious amounts of foam. I did purchase the small diameter stainless steel tube so I might experiment with epoxying a piece of that in the nylon tee to make my machine more in line with the original. You can find a picture of my version here. drive.google.com/file/d/1N4Vn5i8vn-QAd9Z1vpiciENXkKs7nk2m/view?usp=sharing
I'm just going to add this to my previous comment. I added the short piece of the stainless steel tube to the compressed air side of my nylon tee fitting and sure enough, the device now holds pressure well and is producing foam prodigiously. Lesson learned. Go with the eductor, however you manage to put it together.
Thanks for the video. Very impressive design. I have a question. When the air enters the tank, it has two ways to go, compress the air in the tank and it blows out to the wand. Does the compressed air in the tank do anything to help the eductor for drawing the solution?
@@Jimscoolstuff Thank you for your quick reply. So if the air pressure going through the tank does nothing, can we connect the air pressure directly to the eductor rather than connecting through the tank? Maybe I don't understand enough :-)
@@Jimscoolstuff Thank you very much for your very quick reply. I will try to find the hardware and materials to build one. By the way, your design is the cleanest design and the most consistent DIY foam generator I found so far on the net. Thanks again.
Another thought come to my mind but don't know if it will work. Can you give me your opinions? Thanks in advance. If I replace the eductor with a regular tee fitting and insert an air valve in the air line between the tank and the tee fitting to increase the pressure in the tank (by reducing air flow to the wand) so that it push the solution from the tank out to mix with the air at the tee connector. Do you think it may or will work?
Thank you Jim for doing this. I watched your other videos, and the one about eduction. But, on this machine you made, I am not certain about the internal process. Tell me where is the soap coming from? What is its course? What pushes the soap into the wand? Where does the soap and the air merges? I'd appreciate your reply.
@@Jimscoolstuff Thank you Mr. White. Your answer is consistent and verbatim with what you say on your videos. I understand the eduction process from watching your videos, especially the one "....this sucks". That is one generous video Mr. White. Thank you again. On the video above, the air pressure connection on the right side of your machine is clear to me. but I'm not sure where the soap solution is. It's probably in the PVC pipe standing, right? If not, where is the soap reservoir? The hose on the left side connected directly across the air entry goes down. and that's when I get lost and can't follow the hoses and the connections. I am determined to copy your design because it impresses me. So, I'd love if you drew a diagram showing the route travelled by the soap solution, the air flow, and the point of merge before these components get to the wand. I have clear understanding of the wand's internal process from entry to where the foam exits. THANK YOU. CONTINUE DOING YOUR WONDERFUL AND INFORMATIVE VIDEOS. :)
@@Jimscoolstuff Hello Jim. Would the venturi pump you constructed be sufficient to supply the gun with soap solution without pressure in the reservoir? I assume from what I could see that the solution comes from the bottom of the reservoir which appears to be under pressure as the compressed air passes through the top before continuing on to the wand.
Hello Jim, just finished my/your build of the foam generator. I followed your instructions to a "T", but I am not getting nearly the volume of foam output as I see in your demo. I turned the needle valve to about 1/3rd of a turn and adjusted the pressure valve to 80 lbs. The foam is coming out fairly wet and collapsing and not producing much foam/cream as I see in your video. Is it possible I do not have enough fine steel wool in the gun, or my gun is too large (around 9" with the end caps on)? I love the design and it appears the eductor is sucking very well, but the solution is very wet and it takes 5 minutes to fill a 5-gallon bucket. Thanks again for your dedication and feedback.
Hello, Jim! Thank you for making this video it truly inspired me to make my own foam generator and make my wife a lightweight outdoor water fountain. I completed my fountain form and now I am currently in the process of making my foam generator and have a quick question wrt the eductor; I tried filling the top 1/4" of the 1.5" copper tubing with epoxy but the glue was pretty runny and I ended up filling the entire piece of tube with epoxy instead of just the top 1/4". I have not yet drilled the 1/16th hole through the center as I wait for your answer as to whether I can still use this entire epoxy filled tube, with a 1/16th hole in the center, as an eductor? Will I need to drill out with a larger bit from the other end all the unnecessary epoxy leaving 1/4", which was the initial intent? Your quick response is greatly appreciated. Thanks again!
@@Jimscoolstuff Jim, Thank you for the speedy response, I am literally in the process of building the foam generator as we speak. I did not fill the other connectors with Epoxy, just the eductor piece, so it sounds like I just need to drill the 1/16th hole through the entire 1.5" eductor piece. I am sorry to keep asking questions, but I drilled the 5/8th inch hole into the 2" pipe at the top to receive the CPVC stub/elbow and the hole is too large for the 1/2" cpvc. I tried welding it with the glue, but it is still loose. Any ideas on what I can do to fix this for a better fit? I drilled through the side of the threaded 2" PVC cap. Thanks again, I really appreciate your help!
@@Jimscoolstuff Hello Jim, I am wondering if my problem stems from using a hand drill to drill the hole as opposed to a drill press? Maybe I am accidently moving the hand drill just enough to make the hole slightly larger than the 5/8ths? Also, do you use the PVC cement or the cement made for cPVC?
@@Jimscoolstuff Quick quick question. Should I use the epoxy weld to attach the 1/2" cPVC connections to the top and bottom of the 2" reservoir or regular PVC cement? Thanks!
@@Jimscoolstuff That worked perfectly, thank you!!! I figured out what I did wrong with the 5/8ths hole and why I had such a loose fit with my cPVC. I used a 5/8ths " paddle bit instead of a round 5/8ths bit. For any viewers attempting this build I highly recommend avoiding the use of a paddle bit to make the holes for the cPVC. I am sure I speak for all of your viewers when I say your help and rapid responses are greatly appreciated!!!
@Jimscoolstuff Thanks for all your good videos full of good information. I see a number of others have asked about something in the comments on this video, that I am wondering about, but you have not answered them in the comments that I can see. This is regarding if the foaming solution tank needs to be pressurized or can the eductor draw the foaming mixture from an open container? I am looking to build buildings with aircrete and will be needing to make two consecutive batches of aircrete using 94 lbs bags of portland cement, each making 45 gallons of aircrete to fill the molds. It would be helpful to be able to mix the foaming solution in a five gallon bucket or a garbage can and have the eductor suck it from there. I realize that this will mean that the valve will need to be on the airline before the eductor instead of just before the wand. I would be interested to hear your thoughts on this or see a video testing if this will work. Or did you just pressurize the foaming solution tank so you could put the valve just before the wand out of convenience? Thanks!
I don't think the eductor will work as you want. There are other designs that use a 12 Volt DC water pump to suck solution from a 5 gallon bucket. This is probably what you need for large batches of foam. Best Regards.
Hi Jim... Seeing your setup an idea comes to my mind.... What if you put the mixture of cement, water and soap solution inside the PVC pipe and atomize the whole mix??? Would exit the aircrete mixed??? I can't see why not... It would be great to pour in situ directly in the most complicated scenarios... Thanks for your knowledge!
Thank You Mr. White. The foam is richer than any foam in all those other videos. What is the liquid ?? Is it Drexel ? l must have missed it in the video 🤔☺️. By far the simplest machine to make. I will name it.... “The White Genie” 🧞 🥳🙌🏽
Dear Jim, sorry that I go through here again to ask you this (I'm afraid that I won't reach you in 2 weeks on the other side): Does it affect the operation of the system if, for example, I use a 1" larger pipe (not longer)? I had a hard time getting the fluid needle regulator. Can I use another type of regulator? Thank you very much for anything you can tell me. Love from Chile
If you are using PVC pipe you must look at the pressure rating of the pipe. Larger sizes have lower pressure ratings. Also the warmer the pipe is, the lower the pressure that it can hold. Make sure that you do not exceed the pressure rating of the pipe at the maximum expected temperature or an explosion could happen. The nominal pressure rating is for a temperature of 25 Deg. C. The pressure rating goes down rapidly beyond that temperature. You can use any air regulator that can reduce the compressor pressure to the desired pressure. Usually there is a pressure regulator on the air compressor that can be set to any pressure that is desired. It is not necessary to have the pressure regulator at the foam generator. I hope this answers your questions. Please be safe.
@@Jimscoolstuff - Dear Jim, your answer gives me a new perspective about this device. The pvc pipe that I was talking about in fact is a 50 mm diameter pipe. That means -if I'm not wrong- that is the same one that you have used in your project. So, my only concern would be the amount of pressure you would recommend to use for a basic & good performance of this device. Last thing: I've tried to get Drexel in here but it is hateful expensive. So, I look for some other options and I found out that the ingredient that makes it "super foamy" is Sodium Lauril Sulfoacetate SLSA. Instead of the about US$120 that finally would cost me a gallon of Drexel, 5 kgs of this powder cost me here US$25. In the USA I found that only 1 pound costs US$20 (That's expensive!). In the States there is a man (Aircrete Harry) who has made a video where he compares the different products to make foam. Which product do you recommend? Ok Jim, sorry for this book, but I don't want to miss the opportunity to suck the most of your wisdom 😁 Love from Chile
@@Roatanmicky Thank you for the information on SLSA. Perhaps you can tell us the mix ratio to use with this. The design of the wand is to minimize the back pressure as the foam goes through it. Do not pack the steel wool too tightly or the eductor will not work properly. The air pressure mostly determines how fast foam is produced. Good luck with your project and have fun.
@@Jimscoolstuff Dear Jim, I am extremely happy to add something to this conversation. I enclose the link of Aircrete Harry ruclips.net/video/rY-oHAYjQ1E/видео.html He makes some comparisons that seem to me very well analyzed and informed. Regarding your wishes to have fun with this, I inform you that I am in the stage of uncertainty, but quickly approaching (thanks to you and other good people who share their knowledge with pure desire to help) to enjoy it. I only hope to make the airconcrete blocks that will support the game room that I want to build for my wife and son. With love from Chile
@@Roatanmicky Thank you for this link. When I watched the video, I realized that I had viewed it years ago, and had forgotten about the SLSA. I went with the Drexel because it was available and cost effective.
Hello, wery good video!!! I got 5 fail fomegenerators today alone😃 tomorow will try yours. Can I use regular "ball" valfe or it must be pin valve? Hi from Slovenia🙋♂️
@@Jimscoolstuff OSB is often used for roof decking and loses strength when it gets wet. I'm thinking of a concrete product that is *well supported*. OSB roof decking is a very common practice. Concrete won't be negatively affected by water or heat. Conventional roofing materials and related decking are damaged by UV, heat and water. Potentially a concrete product eliminates all three. Think of concrete shingles or concrete tiles - these are well supported and do a fine job. A roofing panel that was supported on a heavy welded wire grid might not crack. I think the primary roof material would be a standing seam metal roof.
@@Jimscoolstuff I think the material I'm looking for is latex cement. Some of the water when making cement is replaced with latex or acrylic. The latex enables a thinner sheet of concrete to be less likely to crack and the concrete is less water permeable. Latex modified cement is used for bridge decks as it resists salts and chemicals which can corrode the structural steel
Jim, the cement material that has the properties I'm looking for it called Laminated ferro cement (LFC). Ferrocement was invented in the mid-19th century and used for boats and canoes, water tanks and roofs. The floating "mulberry" harbors used at D-day were made from ferrocement. LFC is made with layers of fine wire metal mesh and can be as thin as 3/8-inch thick for water tanks. Some use fiberglass insect screening, others have used synthetic fibers like Kevlar. When some of the water is replaced with latex the material is even less brittle and more waterproof. A foamed variety exists but I have no specifics on that material. Here's a link from the University of Michigan deepblue.lib.umich.edu/bitstream/handle/2027.42/84723/ShuxinFerrocement.pdf?sequence=1&isAllowed=y

I did not fill the other connectors with Epoxy, just the eductor piece, so it sounds like I just need to drill the 1/16th hole through the entire 1.5" eductor piece. I am sorry to keep asking questions, but I drilled the 5/8th inch hole into the 2" pipe at the top to receive the CPVC stub/elbow and the hole is too large for the 1/2" cpvc. I tried welding it with the glue, but it is still loose. Any ideas on what I can do to fix this for a better fit? I drilled through the side of the threaded 2" PVC cap. Thanks again, I really appreciate your help!
@@Jimscoolstuff Hello Jim, I am wondering if my problem stems from using a hand drill to drill the hole as opposed to a drill press? Maybe I am accidently moving the hand drill just enough to make the hole slightly larger than the 5/8ths? Also, do you use the PVC cement or the cement made for cPVC?
@@Jimscoolstuff Quick quick question. Should I use the epoxy weld to attach the 1/2" cPVC connections to the top and bottom of the 2" reservoir or regular PVC cement? Thanks!
@@Jimscoolstuff That worked perfectly, thank you!!! I figured out what I did wrong with the 5/8ths hole and why I had such a loose fit with my cPVC. I used a 5/8ths " paddle bit instead of a round 5/8ths bit. For any viewers attempting this build I highly recommend avoiding the use of a paddle bit to make the holes for the cPVC. I am sure I speak for all of your viewers when I say your help and rapid responses are greatly appreciated!!!
Really nice, thanks for sharing
@Jimscoolstuff Thanks for all your good videos full of good information. I see a number of others have asked about something in the comments on this video, that I am wondering about, but you have not answered them in the comments that I can see. This is regarding if the foaming solution tank needs to be pressurized or can the eductor draw the foaming mixture from an open container? I am looking to build buildings with aircrete and will be needing to make two consecutive batches of aircrete using 94 lbs bags of portland cement, each making 45 gallons of aircrete to fill the molds. It would be helpful to be able to mix the foaming solution in a five gallon bucket or a garbage can and have the eductor suck it from there. I realize that this will mean that the valve will need to be on the airline before the eductor instead of just before the wand. I would be interested to hear your thoughts on this or see a video testing if this will work. Or did you just pressurize the foaming solution tank so you could put the valve just before the wand out of convenience? Thanks!
I don't think the eductor will work as you want. There are other designs that use a 12 Volt DC water pump to suck solution from a 5 gallon bucket. This is probably what you need for large batches of foam. Best Regards.
Hi Jim... Seeing your setup an idea comes to my mind.... What if you put the mixture of cement, water and soap solution inside the PVC pipe and atomize the whole mix??? Would exit the aircrete mixed??? I can't see why not... It would be great to pour in situ directly in the most complicated scenarios... Thanks for your knowledge!
Was wondering if you put sodium silicate to the foam if it would help make the foam stronger .keep up the great work 😃
Thank You Mr. White.
The foam is richer than any foam in all those other videos. What is the liquid ?? Is it Drexel ? l must have missed it in the video 🤔☺️.
By far the simplest machine to make.
I will name it....

GOOD JOB. I think i will make one with a 4' pip. I have a lot of parts.
Dear Jim, sorry that I go through here again to ask you this (I'm afraid that I won't reach you in 2 weeks on the other side): Does it affect the operation of the system if, for example, I use a 1" larger pipe (not longer)? I had a hard time getting the fluid needle regulator. Can I use another type of regulator? Thank you very much for anything you can tell me. Love from Chile
If you are using PVC pipe you must look at the pressure rating of the pipe. Larger sizes have lower pressure ratings. Also the warmer the pipe is, the lower the pressure that it can hold. Make sure that you do not exceed the pressure rating of the pipe at the maximum expected temperature or an explosion could happen. The nominal pressure rating is for a temperature of 25 Deg. C. The pressure rating goes down rapidly beyond that temperature.
You can use any air regulator that can reduce the compressor pressure to the desired pressure. Usually there is a pressure regulator on the air compressor that can be set to any pressure that is desired. It is not necessary to have the pressure regulator at the foam generator. I hope this answers your questions. Please be safe.
@@Jimscoolstuff - Dear Jim, your answer gives me a new perspective about this device. The pvc pipe that I was talking about in fact is a 50 mm diameter pipe. That means -if I'm not wrong- that is the same one that you have used in your project. So, my only concern would be the amount of pressure you would recommend to use for a basic & good performance of this device. Last thing: I've tried to get Drexel in here but it is hateful expensive. So, I look for some other options and I found out that the ingredient that makes it "super foamy" is Sodium Lauril Sulfoacetate SLSA. Instead of the about US$120 that finally would cost me a gallon of Drexel, 5 kgs of this powder cost me here US$25. In the USA I found that only 1 pound costs US$20 (That's expensive!). In the States there is a man (Aircrete Harry) who has made a video where he compares the different products to make foam. Which product do you recommend? Ok Jim, sorry for this book, but I don't want to miss the opportunity to suck the most of your wisdom 😁 Love from Chile
@@Roatanmicky Thank you for the information on SLSA. Perhaps you can tell us the mix ratio to use with this. The design of the wand is to minimize the back pressure as the foam goes through it. Do not pack the steel wool too tightly or the eductor will not work properly. The air pressure mostly determines how fast foam is produced. Good luck with your project and have fun.
@@Jimscoolstuff Dear Jim, I am extremely happy to add something to this conversation. I enclose the link of Aircrete Harry ruclips.net/video/rY-oHAYjQ1E/видео.html
He makes some comparisons that seem to me very well analyzed and informed. Regarding your wishes to have fun with this, I inform you that I am in the stage of uncertainty, but quickly approaching (thanks to you and other good people who share their knowledge with pure desire to help) to enjoy it. I only hope to make the airconcrete blocks that will support the game room that I want to build for my wife and son. With love from Chile
@@Roatanmicky Thank you for this link. When I watched the video, I realized that I had viewed it years ago, and had forgotten about the SLSA. I went with the Drexel because it was available and cost effective.
Hi, very nice , do you have diagram i can copy
Great Jim.Thanks again.
why does the foam solution reservoir need to be pressurized? Can’t you just leave it gravity fed?
A large mig welder tip would probably work for your eductor nozzle with no drilling
Hello, wery good video!!! I got 5 fail fomegenerators today alone😃 tomorow will try yours.
Can I use regular "ball" valfe or it must be pin valve?
Hi from Slovenia🙋♂️
Can aircrete be used for roofing deck? Is it lightweight enough and sufficiently strong ? Will it crack under stress?
@@Jimscoolstuff OSB is often used for roof decking and loses strength when it gets wet. I'm thinking of a concrete product that is *well supported*. OSB roof decking is a very common practice. Concrete won't be negatively affected by water or heat. Conventional roofing materials and related decking are damaged by UV, heat and water. Potentially a concrete product eliminates all three. Think of concrete shingles or concrete tiles - these are well supported and do a fine job. A roofing panel that was supported on a heavy welded wire grid might not crack. I think the primary roof material would be a standing seam metal roof.
@@Jimscoolstuff I think the material I'm looking for is latex cement. Some of the water when making cement is replaced with latex or acrylic. The latex enables a thinner sheet of concrete to be less likely to crack and the concrete is less water permeable. Latex modified cement is used for bridge decks as it resists salts and chemicals which can corrode the structural steel
Jim, the cement material that has the properties I'm looking for it called Laminated ferro cement (LFC). Ferrocement was invented in the mid-19th century and used for boats and canoes, water tanks and roofs. The floating "mulberry" harbors used at D-day were made from ferrocement. LFC is made with layers of fine wire metal mesh and can be as thin as 3/8-inch thick for water tanks. Some use fiberglass insect screening, others have used synthetic fibers like Kevlar. When some of the water is replaced with latex the material is even less brittle and more waterproof. A foamed variety exists but I have no specifics on that material.

Brilliant!
Going to place one over the shower.
Excelente!!! Thanks thanks thanks from Argentina. La experiencia hace la diferencia
hola, que seria para nosotros la T que el utiliza? en los comentarios la llaman EDUCTOR, estuve viendo Venturi pero estan medios caros.

Thanks for your interesting comment.
Hi Jim, I've sent you an email. Please, let me know your thoughts about my doubts. Thank you & Love from Chile
I am doing something wrong. Probably because I am not 100% following your guidance. I would like to send you pics of my device and see what you think.
My e-mail is ki8bv@mactronics.net. I sometimes go weeks without reading my mail, so be patient. Use the subject "foam" so I can find it.
