I got the same result sewing an old bed sheet and it was free. Also I've found that if you make a watered down fabric softener mix in a spray bottle it keeps the foam beads from flying everywhere by reducing the static charge so your spray idea should work.

[@AbundanceBuild]

Thanks for the idea Herger. I will try that.

Oh, funny! I just added my comment about that above before finding your comment😂. Maybe I’m not alone in this issue.

[@dennistucker1153]

Love your videos. Version 2 of the shredder is OK. I was a manufacturing engineer that specializes in this kind of factory enhancements. The insulation bag is perfect. The use of an electric lawn mower is great. Here are the changes I would make. 1) Redesign the cowling/container. I would use something like the plastic 55 Gal drum but go clam shell design. (2 piece) fitted for the engine/chopper and seals well. Instead of top opening I would make the container longer and use a top-side feed port. Make it easy to change parts. 2) mount the container high(ceiling/wall), to do this right the top of the container would need to be about 15 feet up off the ground. This is to create a continuous column feed. 3) add a diagonal feed conveyor. 4) then hang the insulation bag from the bottom of the container. You want the exit port of the insulation bag to fit the height of the cement mixer.

[@maigematthews5620]

Ingenious upgrades Dennis! In your suggestion #2: Question, is the reason for this structure change to use gravity to naturally drop the styrofoam into the white insulation bag column? In your suggestion #4: Question, is this solution to completely knock out the moving of the styrofoam from the white insulation bag into the grey garbage container, and then having to pour the styrofoam from the grey garbage container into the cement mixer? If so, great idea, But then how would he measure the amount of styrofoam that is being fed into the cement mixer?

[@heartobefelt]

@@maigematthews5620 You could use two sliding gates , open the first one to fill the 45 gallon bucket , close the first then open the second to dump your 45 gallons of EPS directly into the ribbon mixer , you need to hoist them all up quite high but it would reduce spillage and increase the speed between batches. I would use a grout pump to pump directly from the mixer into your formwork too.

If you add a second blade to the mower and mount it rotated about 60 degrees from the original blade you'll get finer beads. I also recommend adding fiberglass strands mixed into the styro aircrete.

[@alexanderSydneyOz]

These videos are just awesome. Stephen: you definitely epitomise DIY, and I am most impressed by your endless ingenuity. My only contribution is this: regarding castors, my rule now is that everything in a work area that can go on castors, does go on castors. If there are too many, or too heavy items sitting on the floor, then the workspace is inflexible, and you end up discouraging yourself from moving items around. In my case, that includes several work tables, a drill press, 4x pallet rack units, press, etc.

Nice refinement! This really is awesome work. Now all you have to do is turn that mower sideways, rework the chute to enter from the side & you can mount it on a vertical sliding mechanism to raise & lower it for bag height/easy loading of new bags. Inside the chute, just add a brush you can push pieces through to ensure it does not escape for good measure. Looking forward to your next video

[@jkovar55]

I was inspired by your first shredder and made one of my own. I needed 1/4 screen for making blocks (aka -perfect block clone) To help with the chopping, I only have 1/2 the plywood deck open with the half over the exit covered to create a "grinding chamber". i used a 55 gallon fiber drum that fits exactly the 20" mower. My plywood shoot has a 45 degree entry port with the opening perpendicular and having heavy vinyl strips to prevent the blowback. I use the harbor freight dust collector as the added suction enhances the extraction thru the screen. My next upgrade will be adding brushes to the end of the blade to force particles thru the screen as on of your viewers suggested. I too added a switch. Be warned with the single pole switch, the braking after turning off is disabled. I am researching momentary switches to re-enable that function. I have made 2 blocks so far, but am still refining the formulation a both came out a little bit high on the density. Also, I use inexpensive recycle bags on the dust collector and collect the proper amount for one batch (45-55 gals). The recycle bags are fine since the particles of foam don't puncture.

[@bzmrgonz]

Can you share a link to more details or video about the perfect block clone? I would love to see something on that.

[@ozarkhillskennel6855]

Great upgrade! Much cleaner and user friendly. Here’s a couple of ideas. 1. Set the box of styrofoam chunks on a table beside the shredder so you don’t have to bend over each time to get more pieces. Easier on your back and saves time. 2. Put a wye in your discharge tube about a foot into the flexible tube. You can order a hi volume in-line fan sized for that size of tubing from grower supply houses that will alleviate the clogging issue.

[@AbundanceBuild]

Thanks for the tips! Subscribe for updates coming soon!

[@josiahstanley9291]

I love the concept and I could see myself one day collecting scraps from work to replicate this someday. But have you ever rented an insulaton shredder with the hose attachment? Maybe taking one of those machines and attaching an extended feeding tube like you made out of wood. But put heavy rubber ribbons inside, almost like mop hairs all hanging down so you can feed it but when it burps the foam should not spit back. Another thought for combining the styrofoam with the concrete is keep it in the bag but fashion a mattress inflator to a bigger tube with a way to secure it to the bag. That way you can shoot the foam out of the bag into the concrete hopper. Also maybe put a protective hood onto the concrete hopper to help minimize losing foam to the wind. And I see in the comments someone mentioned the concrete spray hose. And I think that would be neat to see for sure. I mean 3d printing housing is on the rise. Great idea though for real man. I hope you have many successfully structures!

[@davidhantz5936]

I don’t know if you have thought of, heard about or already tried this, but I think you could extrude the Styrocrete instead of trying to pump the slurry. If you use an auger something like a post hole auger from a pto inside the right size pvc pipe. You can experiment with different size discharge holes that would effect the density of the slurry. To get the slurry compressed before it enters the form so the consistency of the wall would be the same. A hopper and a Extruder with a hose and you could pump the slurry into a hole in the bottom of the form until it comes out a hole in the opposite side at the top of the form.

[@AbundanceBuild]

Good idea!

[@khandam7709]

use a 5 gallon bucket as your input shoot. it has a 10-12" diameter and you can get them for free from construction sites or a few bucks at lowes. just cut out bottom and use angle brackets to attach to your plywood lid. get a battery powered sprayer and mix water with fabric softener. spray on foam beads to reduce static charge.

[@keralee]

Or dont fully cut out the bottom, leave a flange inside, caulk to block leaks, and just screw that to plywood directly...

[@AbundanceBuild]

Good ideas Khan. Thank you

[@littlecreekhomes-movablelu2829]

@@AbundanceBuild I used the 5 gallon bucket idea on my modified Stephen Williams foam shedder V2 and it works perfect. You have to leave 2 inches protruding below the bottom of the mounting deck to stop the foam flying out. I use a leaf vacuum to cut the off take from the lawnmower to get 1/4 beads. I also use bounce sheets suspended in the hopper and it takes all the static out...nice smell too LOL. Thank you again Stephen.

[@genegreear4183]

I’ve been watching all of your videos. I’m going to be building a house soon and want to do it as cheaply as possible. Here’s my ideals on the shredder. In stead of a lawn more I would use a 110 volt, one horse power motor on the electric switch. The with pilot bearing and pulleys. I would get the speed needed to shred the stereo foam. To get smaller sixes you might try a mulching blade or on with barbs or spikes welded and balanced on the blade. Just use one of those lawn mower blade balancers. If you use spikes make sure they are sharp just like the blade and it will rip them better. The thing about using a plain electric motor is the cost as compared to buying a new lawn. Mower. You can get the deck at almost any junk yard. Later

[@rodneygiles3792]

Before I get into the engineering geek session I first have to give praise where it's due. I just watched all your videos again after a shout out from Aircrete Harry mentioned your "StyroAirCrete" as a solution on stabilizing aircrete in his recent video comparing compression at various depths. (The 12ft column video...) This is looking more and more like my wife's food processor. The main differences are that the chute is offset and the blade is closer to the lid. I have a sneaking suspicion that finer chopping is probably a result of these two things. I wonder if a better design for this use case would be to create an X of 2x4s under the lid to stop the big pieces from jumping around like popcorn. That would also block congestion in the center of then enclosure where backup is more critical. Keep posting updates. Very exciting...

Styrofoam has even more utility than just lightweight/insular aggregate. Its an effective epoxy resin substitute when dissolved in acetone, paint thinners, or even gasoline. Different solvents provide different results in the finished product. Turpentine is ideal for impact surfaces because the pine resin allows for ongoing flexibility whereas acetone will yield a very hard, but brittle, crystal clear plastic. I’ve been remodeling a home using only trash from the beach and styrofoam is beyond useful.

[@AbundanceBuild]

Wow way to go! We have done some tests melting it down but we need to make a video about it!

Uniform individual beads for most applications would be best. Likely require two stage operation. Wider outlet screen here to solve plugging screen. Then the batch is run through a rotating drum (expanded lath screwed to plywood disks mounted on pillow blocks. This would run close to another piece of expanded lath). You have solved the mess problem, and this would surely mean more engineering, but those individual beads sure would be beautiful!

[@Gasp7000]

Great videos! STATIC! 😱😆This is a little long, but worth the read if it works. I have a thought about the STATIC issue with the styrofoam. I used to stuff pillows with the mini styrofoam beads (extra large ones are now used in beanbag chairs), and the static was a big, frustrating issue. So, I put a dryer sheet in a spray bottle of water to mist inside the store-bought bag-and shake it good and hard-before making a larger opening to transfer the beads into the pillow, and sure enough, NO MORE STATIC. WooHOO! If Static Guard, Downy Fabric Softer (laundry anti-static liquid) don’t interact with the foaming solution in the StyoAirCrete, this could be a possible option you could try for dealing with the static issue. Another thought, for under $30, you could install a patio “misting” nozzle, the kind used for cooling off while sitting outside in the heat of the summertime, inside your system somewhere, maybe even as you feed it into the mower shredder from a tank instead of a garden hose, in order to prevent the static issue before it even gets blown into the large bag. If this is something that breaks down the foaming solution chemically once the misted styro bits are added to the whole mix, I guess it wouldn’t work, but it might be worth an experiment-maybe try a small batch of foam spiked with a hint of fabric softener just to see if that batch collapses more than would a batch without it, side by side. Even when I am opening packaging full of static-y styrofoam and bits get everywhere, a fabric softener misting bottle on hand makes cleanup a lot easier and less aggravating. I might even try this experiment myself😉 in styroaircrete. When I saw your entire shop snowed with the shredded stuff, my head instantly went to fabric softener. There may be an organic type of fabric softener that could be used if you are allergic to the artificial fragrances in it like I am.

[@AbundanceBuild]

Cohelix I don't have a wall compression tester yet so I can't give you an answer to this. the stucco skin gives considerable strength to the wall. If you build without any wood trusses in the wall as I did on my shop I would recommend increasing the stucco thickness. Mine is barely 1/8 to 1/4 inch thick. My next project will have wood trusses embedded in the wall which will add to the strength.

[@BigBrotherIsTooBig]

If I was trying to get a finer shred, I'd build a raised platform to put the shredder on and have the bag below it. I think I'd help with the flow using a finer mesh.

He does have rebar that he installs into the forms, after pour the mixture. And when it’s dried, he does line the outside with fiberglass/steel mesh when applying the stucco for structural integrity purposes. I think if anything, we will have to wait on his video postings of pressure tests that he’s been wanting to do.

[@Claycanplay]

Have you ever heard of the Hagfish? I’m guessing that that it’s slime could improve aircretes structural integrity while holding the styrofoam into manageable clumps during the production phase.

[@slyharvey5866]

Really good information and I can not wait to start my new aircrete projects. I am located in Ottawa Canada and I was thinking of doing a radiant garden planter in my passive solar greenhouse using foam aircrete. Would you have any suggestion about using foam aircrete with electric radiant cable?

[@AbundanceBuild]

Hi Sly. Glad this is got you pumped to tackle a project. Aircrete should be used for insulating underneath the slab. And then apply a 3/4 inch to 1 inch concrete topper that will radiate the heat well from the heater. If you embed it in aircrete it will partially insulate the heat from radiating.

I was thinking about purchasing a used 13 amp leaf mulcher/shredder, then installing a high lift lawn mower blade to pull material in, and pushing it out a fine metal mesh beneath the blade where the material exits the bottom. Any thoughts?

[@georgehirvela7435]

I have a Quonset hut-style building in Arizona that I'm considering covering with wire mesh and shooting styrocrete out of a plaster gun. What do you think about shooting this stuff? I'm not too concerned about cracking. Also is pumping a problem, you've probably already done that but I figured I'd ask. Thanks for engaging content.

[@AbundanceBuild]

You're welcome! Pumping is slow and you need a mold to pack the styrocrete in tightly. We dont shoot it or pump it for those reasons. Good luck!

[@ruthdoyle9085]

Don't know if you could use bigger bags but they used to make industrial strength plastic bags to put the big round hay bales in to make silage without a silage pit. Those bags were really long. Can't remember exactly but I bet 50 to 100 ft or more. They were meant to stay outside in the field for months or a yr or so. So if you wanted to grind enough Styrofoam for a whole house b4 you started or wanted to have a Styrofoam grinding business or just wanted to get the grinder and bag out of your shop, this might work. The bags were a little bigger around than diameter of a round hay bale. Wouldn't have to use the whole length of the bag. Check at a big farm supply store or a big haying equipment dealer to see if they still make bags to make round bale haylage.

To be honest, I have to say that I've watched every single video you've posted and I'm really interested about this matter. And the fact that I'm a subscriber too. I'm from Sri Lanka. I would really appreciate if you could let me know about the compositions and ratios of materials added in this project. And also I wanna know whether adding a wired mesh (chicken coop mesh) in-between the wall of air-crete and whether this mixture is made by adding soapy foam. Appreciate all your well understandable videos. Keep up with the good work. I'm waiting your kind response. Thank you.

John yes it would. Watch the Fire test video. You can treat the EPS with Borax and boric acid and it makes it fire resistant.

[@broderickelliott8527]

Would it be worth foregoing upsizing your chute in favor of installing a foam cutting wire on the top edge? Just take your foam and press down and the cut piece falls directly into the chute in one motion.

[@AbundanceBuild]

We thought about that as well. In theory it seems like it but in our experience with wire cutting Styrofoam it is a slow process. We fill up bags quickly this way! And we need to fill a lot of bags to build a house

[@broderickelliott8527]

@@AbundanceBuild Well, for whatever it's worth, I don't have the beautifully conceived set up you do (there's a reason I ended up here tonight,) but I've been cutting my styrofoam up on the band saw. I'm sure with only a little thought you could rig up a slide that would feed from the bandsaw table directly into the chute of your foam shredder. You'd obviously have to get the height right, but that might be the best of both worlds, with or without upsizing the chute. I'm only aiming for medium to small gravel sized chunks to add to traditional concrete in order to improve the insulative value of my foundation. I think your design is exactly what I need.

[@wingnutbert9685]

Not sure if folks have suggested already, but here's my thoughts, for what they're worth: (Sorry, it's gonna take a bit to type. In bed sick with the "you-know-what"....) - Take the mower completely apart so you just have the motor unit, shaft, blade and electronics. Cut a 3/4" plywood disk the O.D. of the top of your barrel PLUS 2". Cut a 1" thick ring out of plywood (make two rings, 3/4" ply, one should do two would be better) You can economize your sheet by making the ring in 1/4 sections as the sections can be nested on the sheet. The ring(or all the 1/4" segments) will have the I.D of the barrel top and the O.D. of the disk. (Can sand back the I.D. a bit so it's not super tight to the barrel top O.D.) Screw this/these to the first disk. Make another disk with an O.D. (or just shy) of the I.D. of the top of the barrel. Screw this, centered on to the first disk. This will make a channel that the barrel lip will sit in. Lay some sticky backed foam tape in the bottom of the channel to make it air tight. In the center of this "Lid", drill a hole this dia. of the mower blade shaft. Mount the mower motor to the 'lid' using the existing mounts on the motor (you may need to make some custom wood blocks/frame to do this, if the motor doesn't have built in flange mounts to just bolt it direct to the plywood). Wire the on/off switch like you did. - For the exit shoot, cut a rectangle hole in the barrel, just below the blade and make a shroud so the direction of the exiting material comes straight off the wall of the barrel in a flat plane, or close to it. For reference of what I mean, look at how the outlet of a ready made wood shop dust collectors impeller housing is designed, or how an old fashion, hand cranked forge blower is shaped (also a lot like the turbo in a car engine). Also look up "Thien Baffle" ( woodgears.ca/dust_collector/separator.html ) This outlet position with give much better air flow and less resistance. - Make sure your blade is oriented so it pulls air in the right direction (sucking in from your in-feed point) You could try to tweak the blade a bit to increase it's fan blade shape for more suction. ------ con't next -------

[@wingnutbert9685]

- To get finer shred on the styro: Add bolts to the blade on the in-feed side. 1/4-3/8" bolts mounted through the blade. Maybe 2" apart. These "teeth" should provide more shredding action. The blade may be tempered back enough to be able to drill it. If not, you can try spot annealing. Meaure and mark wear your holes for the bolts are going to go. *** These holes must be exact and equal on both sides and the bolts/nuts/washers must be equal as well. Any weight different from one side to the other is going to put the blade out of balance, cause vibration and could be a big problem!*** Use a center punch or small drill bit to make a dimple on each mark. Take an old, large size drill bit or, better yet, an old carbide tip masonry drill bit and run it in reverse, in the dimple. This will create heat and change the color of the steel. This heat will soften the spot with little propagation to the rest of the blade, so it retains it's hardness. Once tempered back, you should be able to drill your bolt holes. 2" bolts should be plenty. Maybe 3 per side. And definitely use nylock nuts! With the smaller size styro particles, you should be able to use smaller expanded sheet like you friend used. Plus, with the expanded sheet, you can bolt that to the outlet, inside the barrel, rather than glue. Better for playing with mesh size and maintenance. - You may want to play with having a larger outlet size. This might slow the exit velocity, letting the styro remain in the shedder for just a bit longer to get shredded. - Instead of a barrel, you could use a big rubbermaid garbage can. ----- con't-------

[@wingnutbert9685]

- Static dissipation: Try grounding the barrel with copper wire. Also could try introducing water. Run a pipe into the barrel from a kettle to intro. steam. Or get one of those ornamental pond vaporizers in the barrel. - Could also try adding a second blade, perpendicular to the first to get more chopping action. Might be the easiest thing to try first.

how much reduction in volume do you get after shredding all the scrap styrofoam? if one has a trailer and an inverter this couold be taken to furniture stores or appliance instalation companies and foam could be shredded onsite. big bags loaded on trailer and brought home.

[@AbundanceBuild]

Khan it would cut the volume down by around 40%. Yes this is possible but I typically am tight on time to go and collect and they don't want you hanging around any longer than to pick it up and go. I can shred in the evening anytime I have free time.

Stephen, have you experimented with the sharpness of the mower blade? Perhaps a sharp blade cuts part of the Styrofoam to dust while a duller blade might generate more evenly sized balls. Of course this is just a wild guess.

[@michaelyoung1892]

Stephen. Have you tried a hybrid mix. I was wanting to try a papercrete/styrocrete mix. maybe go 50-50 on the paper pulp and the styrofoam. The paper pulp fiber locks together and the styrocrete should give you a much lighter mix with better insulation than straigt papercrete. The idea is a stronger material (due to the fibers locking) and a better insulative product. I haen't tried it yet. have you?
