I Built A Smokeless Fire Pit With Foam And Concrete That Actually Works

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.

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

I LOVE when people don't edit out their mistakes. It gives me more confidence as a DIYer. It's great to know that can be a normal part of the process.

Your wife snorting at your mistake - GOLD! I oft hear that same snort from my wife. It encourages us to do better.

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.

Imagine the real estate agent if you guys ever sold your house. "Sir, why is there 13 smokeless fire pits on the property?"

I like how you do not edit out your mistakes. Humanizes you to the viewer. Great job on the pit!

The diy smokeless fire pit got me to subscribe 3 years ago. Still watching today. 😂

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.

"Y'all better red-neckorize." Thank you, Uncle Hax, thank you.

That mud mixer looks awesome! They really need to get them in every Home Depot rental location.

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.

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.

Thank for not editing your mistakes. It’s so much more educating. Great Video; a project I’d like to tackle one day. (Ironically I did edit this comment 😅)

Im 28 and its happening… these are the things i like to watch and do in my free time😭😭

The all thread not to be confused with the all spark because that makes a transformer come back to life is one of the reasons I watch this channel

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've been following you for 3 years. wow! already!

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.
