I am a mason with 40 yrs experience. Excessive heat can cause concrete to explode if there is trapped air or moisture inside of it . I have personally seen this happen on two separate occasions. I would not allow my family to sit within 20 feet of a concrete fire ring. A safer alternative would be a dry stacked ( no cement ) sedimentary stone .
I'm just some dude who once had a flying piece of concrete end up behind my ear when it exploded during a fire. Can confirm, this is a terrible fire ring. Looks great, but I wouldn't sit near it.
As a fellow DIY'er, one thing I've learned is there really isn't a mistake that can't be corrected. It's just a matter of accepting it and taking the time to fix the mistake.
I worked in construction in the 80s and I recall an on-site engineer that always watched as we poured concrete. I asked him why? He made sure the concrete workers vibrated the mix properly. There's not a lot of strength in bubbles was his reasoning. I've always remembered that.
@austinatkins408 true speaking, I have seen some bad segregation from over-vibrating the slurry. End up with severe honeycombing on the lower portion of the pour.
You can also use a short piece of rebar to "rod" the concrete mixture and consolidate it to get the air bubbles up to the surface. Similar to "rodding" a test cylinder.
The perfect amount of humor to keep me engaged, the unedited mistakes, the narration explaining the process, and the logic behind decisions made all helped me thoroughly enjoy this video and subscribe for more in the future.
Just showed this video to the wife. She just sighed and walked away. Still, I didn't hear an explicit "no", so looks like I've a project for the summer, boys! Thanks again, Haxman
For real. I learn on my own and do my projects on my own. When I see someone successfully completing projects while breaking parts and buying tools which don't get used. I genuinely feel like less of a failure.
I did a smokeless fire pit conversion to an already existing pit at a house I bought a few years ago. Did almost the same exact thing you did, I just didn’t have to build the walls. Used a galvanized ring, drilled the holes and set it in the middle with a gap for the outer chamber. Then did the capstones using the same technique, just used melamine board for my form instead of foam board. I only made one form and used it for four pours to give me 4 capstones. Used a bit of old motor oil for my release agent, and added coloring to match the existing walls of the pit that had been already done with landscape blocks. Color matching was the toughest part of the project! It turned out great and works awesome. If I had done the whole thing from scratch, I would have just made the whole thing a bit smaller. Having a 3’ diameter inner ring means you need to make big fires (as you mentioned) and it takes a little while to heat up for the smokeless effect to occur. That’s probably why the commercial ones are fairly small as well. You earned a subscriber, as your rolling storage system has been on my list of stuff as well, just instead of strut channel and trolleys, I had planned to utilize barn door track and rollers instead. Like minds think alike, and I look forward to watching your other builds instead of filming any of my own, lol.
To be 100% honest. I only clicked video out of pure curiosity of how you were going to separate the foam from the concrete. Watched whole video. Learned a lot. Thank you. ❤
This is what life is all about. Creating projects, family, and the land to do as you please. Literally found this channel this morning and binge wathed 6 already and subbed. Love it dude keep rocking!!
Awesome for hotter climates. I like a firepit for warmth when it's cool and that's always been my issue with the smokeless pits because there's very little radiant heat if you're siting beside it. Cool none the less!
I worked at a rehab facility that thought it would be awesome to take a commercial 6' concrete planter and turn it into a firepit for the residents to have bonfires around during their nightly check-ins. It was pretty awesome for the first few nights, but on the third or fourth night they used it, the damn thing exploded and sent cinders, sharp chunks of concrete, and burning wood flying everywhere. Turns out that, even with proper agitation, concrete is still a very porous substance. Air expands when heated, which could turn your fire pit into a time bomb. This becomes even more likely with repeated heating and cooling. It's why refractories tend to be built with ceramic substrates and not concrete.
This one will probably do okay because of the airflow between the metal and concrete keeping the concrete cool. But yeah, concrete also soaks up water, and when water turns to steam, you get ker-blewy.
The bursting isn't primarily about the bubbles. When concrete hardens, much of the water you mixed it with is chemically bound into the new crystals that are formed. The concrete can be bone dry years later, but that water remains part of it. When it gets very hot, it changes chemically, and the water is freed up. The trouble is, it's inside concrete, so it cant expand, and thus it can get extremely hot without becoming steam. But when the solid matrix cracks, it suddenly releases all that pressure at once and bang.
Good stuff all round. Great content worth learning to try at home-and great humor as well. Also like the fact that there's no cussing, no metal or "rap almost music" to deal with. 👍
ALSO ALSO pro tip.... WAIT AT LEAST 20 days BEFORE BURING A FIRE! There is a lot of water still free in the concrete and it is possible to create bad cracks! ALSO ALSO.... keep it wet for 7 days... spraying it with water and covering with plastic. Anyways.... just concrete things.
Not an urban myth!! I have pictures to prove it. The metal liner and gap behind it offered enough protection here which is a good thing but it is 100% guaranteed that green concrete explodes if the moisture turns to steam and I mean explode in a dangerous way. It takes about five beers long after the fire gets cooking. We were lucky.
I like mixing my cement a bit wet when I pour. It's a lot easier to work the voids out of the concrete when doing something like this. Great video man! Thanks.
Not sure if it was mentioned, but rock salt is a great way to add texture. Just sprinkle a little in the form sparingly, and it dissolves later. It can also be added when finishing a sidewalk, just sprinkle some on the concrete before it sets up too hard, and trowel it into the surface. Great video.
@@benholler1389 It's only bad for the concrete if you constantly let salt into the the pores through freeze and thaw cycles. So your comment is partially correct. The salt used for this texture technique is rinsed out as soon as the concrete is hard enough to handle a spray nozzle, and is used sparingly for a random texture. My parents have 40 year old walk ways that I helped my dad pour as a little kid, using the rock salt method, that still look like new to this day. Granted, I'm not a fan of textured concrete... I prefer a broom pass so light that you can hardly tell it was done.
I had to chuckle. A true DIY’er! Stuff happens, but the goal doesn’t change. I’m sure there will never be those who critique the build, but I’m one to applaud the perseverance. This is a short but sweet vid and I’m going to add this to my list of what I need to do this year. My original fire pit was made from those big box pavers, and while it took a couple hours to build, it looks like…well, let’s just say it looks like a big box build. Many have them. I want different. I need to remember to keep that seed oil handy for my release agent! Very good job.
Love that you don't edit out your mistakes, definitely subscribing. Wife made the mistake of giving me the clear to do whatever I wanted to the backyard...so this is definitely in the cards haha

One of the easiest and stupidly brilliant pseudo concrete vibrators I'd ever seen whipped together was an oscillating cutter with a pipe strapped to it. Sink the pipe with it on, goes in like hot butter. I wish I'd come up with that one! I've also picked up an industrial vibrating head for various projects that can be had for like $35 and use metal worm clamps to put all kinds of things under Serious vibrational power. I have one mounted to a stainless thermos with 1,000 5/8ths ball bearings in it for grinding hard media into powder. Murphy's Soap in the huge jugs also works great as a release agent for molding, and you can let it dry and build up layers if you want, or just slather it on and pour. Last time I bought it I believe was 2022 and it was $6 at the hardware store. The only thing I'd address would be drainage, particularly in areas with more clay in the soil than average. You can use PEX tubing and cast them directly into the concrete and run them wherever convenient or pull it after the concrete cures and shrinks off the surface some. It helps a lot with premature rusting of the inner ring so runoff doesn't pool up in the bottom. I'm definitely going to borrow that all-thread trick next time though. So we're even. 😉
Can you explain a bit more about exactly how you'd attach the pipe to the sawzall to use it as a concrete vibrator? I can't seem to figure out what you mean 😅

I love the video. Very informative and entertaining as well. I will mention concrete poisoning is a real thing and everyone’s tolerance is different. Always a safe practice to wear some type of glove while getting your hands on wet concrete. Just saying.
Dude, ur hilarious. The videos are great. But the occassional self jab, or timely quips are priceless. Just subscribed. I'm looking forward to checking out all ur content. Excellent video.
I love it. Can't believe it's been 3 years already. I've always called those tape measures as sewing tapes', but I think they are actually called "Tailors tape" because if you google search that name a butt-ton of results come up.
I knew it - when you didn’t show the application of your release agent, you forgot it 😂 God bless you and your wife! What a trip. Gonna show this to my husband. We move from the burbs to 3 acres in a few months. Smokeless fire pit is gonna be ideal this holiday season! 😁
If you type in your diameter in inches on the construction master calculator and hit the circle button it will give you the circumference as well. Built in short cuts. Invaluable tool that keeps me efficient on the job site. Love your work.
the problem with polystyrene (compared to wood) is that it takes in excess of 500 years to breakdown..and recycling of it is rare...whereas 1/8" ply and 1/4" ply can break down in less than 15 years..we stopped using it for construction for this reason and have gone to using 1/8" and 1/4" for forming

You sir, are the man! I have been planning to build 3 gas fire pits in my backyard (yep, that is a long story) your instruction, expertise and ahem humor will turn my dream into a reality! Thank you. I have subscribed. Yours is the first you tube thing that I have ever subscribed to, only took me 63 years. (Hope I did it right). Iam a BIG FAN. Most respectfully, mike USN ret.
I would advise against that. You're not really supposed to make fire pits, grills or smokers out of concrete. You need fire bricks, they're made of ceramic and they are designed for this application. They're used in kilns, fire boxes, diy fire pits and smokers. You don't want to mess around when gas lines are involved, concrete can explode which could create a very dangerous situation.
HAXMAN, this is AWESOME!!! I'm retiring at the end of the month, and this seems like the logical first project I should get done before fall, thanks!!! Yup, I'm taking 2 months off and I AIN'T DOING NUTHIN!!!
Also...THANKS for leaving the bloopers in...they are what make your channel so relatable. Most you tubers would have easily edited out the bloopers and disguised the real world challenges.
I appreciate your SUCCESS/FAILURE, your SORROW/JOY, and that you are showing this along the way to the really sharp projects that you do. It has a better feel than the slick productions that have the viewers feeling unworthy! I am working on my smoosh technique - to be gentle.
One fantastic project. I have seen a video where the man cut a 2 foot 1/2 inch pvc pipe and duct taped to the reciprocated saw and stocked into the concrete form for smother finish. Well done
Sonatubes work great too man. Get a 3' and 4' sonatube and cut whatever height you want. We use them all the time on firepits. We actually take fire brick and ratchet strap them to the inside piece and the concrete locks it all in once concrete is poured.
@jellman101 not if you do a bunch of them and cut them to whatever height you want. We do quite a few custom firepits and as with most companies labor is our biggest expense. You can't really mess up sonatubes they are done, kick it off, strap your fire brick to inside, pour and you're done other than carving or rock work. Every company is different. If you don't have many employees and don't do many of these in a year then you're 100% right
I’ve found a better way of vibrating the bubbles out. Attach a piece of pvc pipe on an oscillating tool. Screw it on an old blade. Stick it into the cement and turn the tool on high. Works better than the reciprocating saw.
Studies have shown the longer you keep fresh mixed concrete wet, the harder and more durable it will be due to lime crystallization. Great video though! Seriously considering building one now lol
Concrete does not hold up well to high heat. If you don't believe me. Take a torch to it and I hope you have your PPE on. With that said this might work because it doesn't let the concrete to get that hot (unlike standard fire pit). I will stay tuned for the results.
I made a video about this actually on the first pit. The sides are protected by the fire ring. The top doesn’t get hot enough to be affected. As long as you don’t light a fire right after a huge rainfall there are no issues. I deliberately tried to crack the original pit I built with heat and couldn’t do it. You are correct about heat and concrete. If you made a fire directly on concrete that would be a problem.
@@HAXMAN Hey mate, I've seen concrete explode, The fire was actually lit on the slab, it really does go off...!! I'm pretty sure you can get concrete that's better suited to heat...
I build these for a living and I can never avoid that unfinished look that you rubbed concrete on, I don’t care how much I vibrate. I usually just strip the out forms while wet and do so very carefully. I use a product called force cement for vertical stamping. So usually I get it like you got it there, then I apply a stamp mix that you can work for like 16 hours, it’s amazing. That was a really good video! I never knew that about baking soda? I always order the mud but guys that use bags utilize dish soap I’ve heard? Dawn dish soap? I guess it adds air to the mix, which you always want with outdoor and it makes the mix creamy. I’d check on this before doing it because I’ve never done it. But really cool how to turn them smoke free. Again, great video!
Pretty dam cool! Enjoyed your video, as well as you pointing out your errors. Helps everyone learn. The baking soda finish trick was a new one that I didn't know about. Really good job on your video
Okay a couple of comments. I built one just like the video three years ago. It worked exactly as you indicated it would in your video. So very good! Now, the cap plates on ours broke the first time we fired up the pit. This was three days after they were poured. The water still trapped in the hardened, but uncured concrete, caused them to forcefully pop and break. So let that concrete fully cure before applying the heat. Secondly, As I said, it worked exactly as you said it would. What you didn't mention was that it consumes copious amount of fuel. In my estimation 3 to 4 times as much fuel. I had to take it out simply because I could not afford to feed it. It is a proven method for getting a hot fire that consumes its own smoke. The problem is I am not using this fire to forge metal. I'm not even using it for heat. A little fire and some friends; that's all that's needed. So you might mention the fuel consumption issues when you promote these smokeless fire pits.
I like how you routinely mix your concrete too dry, despite knowing better. I too enjoy underfilling my tractor tires, waiting too long to mow the lawn, and under-buying lumber for my next project.
Great video bro!! I'm going to give this a shot. And you have my subscription. Your dynamic with the wife seemed a lot like me and my wife....I said yep he goes what we go through my wife hates when I do stuff on the porch...lol
PLEASE wear a respirator when you play with concrete!!! Concrete dust is silica...which is glass...which means you're breathing tiny shards of glass. Silicosis is a very real thing!! It's a great project, and you've inspired me to build something similar...but please be safe when dealing with concrete. It will kill you, slowly and painfully!
This is about the dumbest thing I have read. The basic kn95 mask doesn’t protect you from silicosis. Silica itself is used to make glass, concrete and similar products and that’s what you don’t want to breathe in.
I've been mixing mortar for 10 years now. I've been breathing it in nearly every day. I've always wondered if it's damaged my lungs and also if that's why running is so hard to breathe after a while. What do you think?
Indeed, that’s why I don’t take any of these DIY videos seriously. 99 percent of the time it’s shortcut scab work. Looks pretty for awhile; until it shows its true colors.
I built mine with a steel pipe under ground going into the bottom of pit. Faced other end to the south, since we have predominantly south winds. South wind goes in the pipe and into bottom of fire. Works great and cost me nothing. Had the pipe paying around.
Planning to print one of these soon / perfect example case of where printing directly instead of using molds will save hours of work. Will also use a fire-safe cement (Geopolymer)

Yep concrete explodes at 1100°F but it becomes brittle around 400° F

And at the same time you don’t want to vibrate too much. Separates the aggregate.

Nowadays we just order it pre-vibrated from the batch plant. Problem solved!

I'm definitely going to borrow that all-thread trick next time though. So we're even. 😉
Can you explain a bit more about exactly how you'd attach the pipe to the sawzall to use it as a concrete vibrator? I can't seem to figure out what you mean 😅

Best I have seen. Love the bbq addition. Needs a pavilion roof. Currently finishing a smoker moving to oven next.
I love the video. Very informative and entertaining as well. I will mention concrete poisoning is a real thing and everyone’s tolerance is different. Always a safe practice to wear some type of glove while getting your hands on wet concrete. Just saying.
Dude, ur hilarious. The videos are great. But the occassional self jab, or timely quips are priceless. Just subscribed. I'm looking forward to checking out all ur content. Excellent video.

Yep....that was the hook 🪝
same for me too! I built that one then, maybe I'll have to build this one too...
Same here
Loved it! Great show & sense of humor!
I love it. Can't believe it's been 3 years already. I've always called those tape measures as sewing tapes', but I think they are actually called "Tailors tape" because if you google search that name a butt-ton of results come up.
Thanks!
Yeah, my mom called them seamstress tapes
Mud mixer is awesome, I wish I could convince myself to buy one. My old lady would beat me silly if I did... But I sure would like one!
I knew it - when you didn’t show the application of your release agent, you forgot it 😂 God bless you and your wife! What a trip. Gonna show this to my husband. We move from the burbs to 3 acres in a few months. Smokeless fire pit is gonna be ideal this holiday season! 😁
Congratulations on the move!
If you type in your diameter in inches on the construction master calculator and hit the circle button it will give you the circumference as well. Built in short cuts. Invaluable tool that keeps me efficient on the job site. Love your work.
the problem with polystyrene (compared to wood) is that it takes in excess of 500 years to breakdown..and recycling of it is rare...whereas 1/8" ply and 1/4" ply can break down in less than 15 years..we stopped using it for construction for this reason and have gone to using 1/8" and 1/4" for forming
Nobody cares

Finally, a comprehensive example! I can't wait to build this for myself!! Thank you for the education!!
Imagine the real estate agent if you guys ever sold your house. "Sir, why is there 13 smokeless fire pits on the property?"
"i just don't think it was realistic that they could've cremated that many bodies in that much time, ig I'm a skeptic"
Because 14 would be RIDICULOUS!
Find another real estate agent, 13 isn't a logical basis for superstition.

Just turn them into raised garden beds
You sir, are the man! I have been planning to build 3 gas fire pits in my backyard (yep, that is a long story) your instruction, expertise and ahem humor will turn my dream into a reality! Thank you. I have subscribed. Yours is the first you tube thing that I have ever subscribed to, only took me 63 years. (Hope I did it right). Iam a BIG FAN. Most respectfully, mike USN ret.
I would advise against that. You're not really supposed to make fire pits, grills or smokers out of concrete. You need fire bricks, they're made of ceramic and they are designed for this application. They're used in kilns, fire boxes, diy fire pits and smokers. You don't want to mess around when gas lines are involved, concrete can explode which could create a very dangerous situation.
I was here for your first smokeless fire pit and here I am today for your second fire pit
Thanks!
This came up on my feed. Randomly seemingly. Good job HAXMAN, very satisfying and I may want to give this a try!
"Y'all better redneckorize!" I don't watch enough of your videos, but I'm going to fix that, haha. Great video man. Very inspiring.
HAXMAN, this is AWESOME!!! I'm retiring at the end of the month, and this seems like the logical first project I should get done before fall, thanks!!! Yup, I'm taking 2 months off and I AIN'T DOING NUTHIN!!!
Great build. The end cracked me up with you trying to find a place to store those 'disposable' molds!!! The struggle is real. 😄😄😄
Also...THANKS for leaving the bloopers in...they are what make your channel so relatable. Most you tubers would have easily edited out the bloopers and disguised the real world challenges.
Wow that mudmixer sure would be amazing to have on hand for concrete projects! The new fire pit looks great!

This guys reminds me of myself when doing home projects that I've never done before. Trial and error, baby! Love that he has fun with his mistakes.
I appreciate your SUCCESS/FAILURE, your SORROW/JOY, and that you are showing this along the way to the really sharp projects that you do. It has a better feel than the slick productions that have the viewers feeling unworthy! I am working on my smoosh technique - to be gentle.
One fantastic project. I have seen a video where the man cut a 2 foot 1/2 inch pvc pipe and duct taped to the reciprocated saw and stocked into the concrete form for smother finish. Well done
"Y'all better red-neckorize." Thank you, Uncle Hax, thank you.

I can always count on your amuzing informative genius, to entertain and teach at the same time. Thank you for that!
Sonatubes work great too man. Get a 3' and 4' sonatube and cut whatever height you want. We use them all the time on firepits. We actually take fire brick and ratchet strap them to the inside piece and the concrete locks it all in once concrete is poured.
Way more expensive than foam
@jellman101 not if you do a bunch of them and cut them to whatever height you want. We do quite a few custom firepits and as with most companies labor is our biggest expense. You can't really mess up sonatubes they are done, kick it off, strap your fire brick to inside, pour and you're done other than carving or rock work. Every company is different. If you don't have many employees and don't do many of these in a year then you're 100% right
love your videos, thanks for all the effort you put into them
My son is 59 years old. You remind me of him. I love your sense of humor.😊
Love it! I also appreciate your intentional/instructional mistakes that teach us what not to do.
I’ve found a better way of vibrating the bubbles out. Attach a piece of pvc pipe on an oscillating tool. Screw it on an old blade. Stick it into the cement and turn the tool on high. Works better than the reciprocating saw.
Rotary hammer drill on hammer mode works great too !
Or better yet just use your wife’s dido 😂

Studies have shown the longer you keep fresh mixed concrete wet, the harder and more durable it will be due to lime crystallization. Great video though! Seriously considering building one now lol
Concrete does not hold up well to high heat. If you don't believe me. Take a torch to it and I hope you have your PPE on. With that said this might work because it doesn't let the concrete to get that hot (unlike standard fire pit). I will stay tuned for the results.
I made a video about this actually on the first pit. The sides are protected by the fire ring. The top doesn’t get hot enough to be affected. As long as you don’t light a fire right after a huge rainfall there are no issues. I deliberately tried to crack the original pit I built with heat and couldn’t do it. You are correct about heat and concrete. If you made a fire directly on concrete that would be a problem.
@@HAXMAN Hey mate, I've seen concrete explode, The fire was actually lit on the slab, it really does go off...!! I'm pretty sure you can get concrete that's better suited to heat...
@@HAXMAN Why not just get castable refractory cement and avoid the problem altogether?
Heat rises
@codycampbell2607 in high-school yeah it does but in the real world it conducts and convects w surfaces.
I build these for a living and I can never avoid that unfinished look that you rubbed concrete on, I don’t care how much I vibrate.
I usually just strip the out forms while wet and do so very carefully.
I use a product called force cement for vertical stamping. So usually I get it like you got it there, then I apply a stamp mix that you can work for like 16 hours, it’s amazing.
That was a really good video! I never knew that about baking soda? I always order the mud but guys that use bags utilize dish soap I’ve heard? Dawn dish soap? I guess it adds air to the mix, which you always want with outdoor and it makes the mix creamy. I’d check on this before doing it because I’ve never done it.
But really cool how to turn them smoke free. Again, great video!
Ok, Ill admit it, I laughed out loud with the "then it hit me joke"
Pretty dam cool! Enjoyed your video, as well as you pointing out your errors. Helps everyone learn. The baking soda finish trick was a new one that I didn't know about. Really good job on your video
Im 28 and its happening… these are the things i like to watch and do in my free time😭😭
Welcome to the club... LMAO 🎉
It’s too late, the algorithm has found you. There’s no getting out now. Enjoy adulthood.
Okay a couple of comments. I built one just like the video three years ago. It worked exactly as you indicated it would in your video. So very good! Now, the cap plates on ours broke the first time we fired up the pit. This was three days after they were poured. The water still trapped in the hardened, but uncured concrete, caused them to forcefully pop and break. So let that concrete fully cure before applying the heat. Secondly, As I said, it worked exactly as you said it would. What you didn't mention was that it consumes copious amount of fuel. In my estimation 3 to 4 times as much fuel. I had to take it out simply because I could not afford to feed it. It is a proven method for getting a hot fire that consumes its own smoke. The problem is I am not using this fire to forge metal. I'm not even using it for heat. A little fire and some friends; that's all that's needed. So you might mention the fuel consumption issues when you promote these smokeless fire pits.
Your definition of easy is nowhere near my definition.
😂
If I ever end up with enough land to do stuff like this, I'm definitely circling back to this video. Thanks man!
I like how you routinely mix your concrete too dry, despite knowing better.
I too enjoy underfilling my tractor tires, waiting too long to mow the lawn, and under-buying lumber for my next project.
those mud mixers are nice for projects like this one or for small footers or a small patio slab
0:06 What I want to know is, why is this guy sitting around a fire pit with my family?
Great video bro!! I'm going to give this a shot. And you have my subscription. Your dynamic with the wife seemed a lot like me and my wife....I said yep he goes what we go through my wife hates when I do stuff on the porch...lol
PLEASE wear a respirator when you play with concrete!!! Concrete dust is silica...which is glass...which means you're breathing tiny shards of glass. Silicosis is a very real thing!! It's a great project, and you've inspired me to build something similar...but please be safe when dealing with concrete. It will kill you, slowly and painfully!
This is about the dumbest thing I have read. The basic kn95 mask doesn’t protect you from silicosis. Silica itself is used to make glass, concrete and similar products and that’s what you don’t want to breathe in.
@@barretisaacs7718 that's why I said a respirator, not a mask.
I've been mixing mortar for 10 years now. I've been breathing it in nearly every day. I've always wondered if it's damaged my lungs and also if that's why running is so hard to breathe after a while. What do you think?
If the silica doesn't kill you, the poisonous gas from heating the galvanized metal will.
You should use the reinforced Quickrete with the fiberglass (Orange Bag). Thanks for the awesome video!
that thing is going to crack and fall apart in a few years...
Indeed, that’s why I don’t take any of these DIY videos seriously. 99 percent of the time it’s shortcut scab work. Looks pretty for awhile; until it shows its true colors.
There's not a better feeling that you make this and enjoy it! I love that feeling of accomplishment!
You're using the word "whenever" incorrectly sir. Whenever refers to at least a plural, you keep using it in the singular with specific instances.
Thanks queer
Absolute champion. Love people who engineer, plus build with their own hands !!!!!!
Awesomeness. I am a former concrete worker, and this is great idea
Thank you for the ideas. I love that you don’t take yourself too seriously!
It’s called a fabric tape measure. We have just found your videos and find you very helpful and entertaining!
I watched this twice now. Another great video………. And HaxMan is looking fit!!!!
I built mine with a steel pipe under ground going into the bottom of pit. Faced other end to the south, since we have predominantly south winds. South wind goes in the pipe and into bottom of fire. Works great and cost me nothing. Had the pipe paying around.
Great video! Enjoyed watching with my daughter. Looking forward to making one like this ourselves!
Awesome! Thank you!
Good job man ,thanks for the cool project idea
The molds are so aesthetically attractive! I am infatuated with them
Creativity gets me up in the morning, once you get in your unique creative flow ... sweet
Planning to print one of these soon / perfect example case of where printing directly instead of using molds will save hours of work. Will also use a fire-safe cement (Geopolymer)
That’s an amazing idea great work
Hey bud, I dig your videos mucho, and great sense of humor brother!!!! That Mud mixer is fantastical 🎊 🎉
Having worked in the CONCRETE industry for almost 30 years Thank You for calling it CONCRETE and not Cement like so many novices.
