Making Green Sand From Kitty Litter For Aluminium Casting
Вставка
- Опубліковано 15 жов 2015
- I show how to test kitty litter for bentonite clay, grid the kitty litter to get a fine powder in a junk homemade ball mill and then show how I mix the sand and water to make the casting sand. You will need to experiment to see what ratio works best for you.
If you want a filter like mine look for "Mesh Flour Sifter Sieve" on eBay. They are super cheap.

Finally someone who says aluminum right 🤩
Thanks man great video exactly what i was looking for i love that ball mill too nice and simple for starting out! Thanks
What you are aiming for is @ 10 to 12% bentonite clay to sand. Try using a batch method with a cup or container. or you could weigh the ingredients.
I did like the El Cheapo ball mill though.
I learn so much from you mate!
i have only heard about the sand/kitty litter thing working, but it is great to see it actually done
+thestalkinghead Yeah! It took me a while to get around to actually trying it!
I like the ball mill you made: much easier than what I did. For my Gingery lathe project, I stole my wife's hand crank wheat grinder and ground up enough kitty litter for 100lbs of green sand. It was good exercise, but took too long to make. More recently I bought some southern bentonite and black diamond sand from Lancaster Foundry Supply in eastern PA. Shipping to Georgia was pricey but not prohibitive. $10 for 50lb bag + $30 UPS.
+Makercise Thanks! I thought about using a hand crank wheat grinder. I thought the gravel in the kitty litter would kill it though. We have the grinder for survival situations so it needs to be in working order... I should look into getting some sand from them as I live in PA.
another awesome video I am looking forward to the casting videos.
+Richard Wheatley I should have a video with the first cast using it up a a few days.
Thanks, I've wondered how I could make some green sand without having to order specialty supplies, I've watched a few of your videos, you're a very impressive young man and have given me some hope for your generation.
You sound like an old man whining about today's generation.
Simon, you sound like a young punk that thinks he's done everything.
+Shane K Calling me a punk as if it were a bad thing just further proves how old you are.
+Shane K Oh right, old people only use slang, stupid me. Other than that good arguments, you got me good.
You started it Simon, I was just paying a complement to a young man with potential.
AWESOME Thanks for posting.
Just wanted to share that I bought a 50 pound sack of bennonite for 37.50 from a ceramics supplier nearby and it's the constancy of fine flour, no clumps. I use 2 parts bennonite with 8 parts sand which I've had good luck with so far.
+Clarke E Cool! That's pretty cheap and it sounds like really good quality stuff too!
Excellent demonstration on the difference between kitty litter with bentonite clay vs without. No one ever shows this and its really hard to find kitty litter that plainly says bentonite clay.
Excellent...Nicely done, thanks for the video..👍🏻👍🏻👍🏻, (Subscribed)
Doesn't have to be the best stuff in the world it looks like it'll do the job
Good video.
can I add oil instead of water?
Also, Dustless kitty liter has more bentonite in it.
what mil screen did you use to screen it?
going to try making some green sand in the near future, I am using discarded glass beading media (free) and it looks much finer than most sand so hoping for a better casting finish I also got my powdered bentonnite clay from a seller on ebay 2 pounds powder for like $10
+Todd Morrill Oh for like sand blasting? Good luck!
let ya know how it turns out...
Thanks for the ball mill idea! I modified by putting arbors on both ends and just stuck it on my lathe at the lowest speed. How long do you normally run it for?
+May the Schwarz be with you that would work great! As long as your lathe spins slow enough. Check on it every hour and shift out the fine stuff and put the course stuff back in with new for another round.
Um, don't you mean bentonite?
ben·ton·ite
+William Labes LOL yeah my pronunciation isn't that greats!
No worries. I just wanted to make sure. Sorry if I came off like an ass.
I'm actually going to follow your method to make green sand pretty closely. Out of the many I've read about and watched this one seems to be the best end result for the least amount of work.
Also, have you looked into adding like a mineral oil? I've read about some green sands using engine or mineral oil in their mix.
William Labes No you didn't sound that way.
Thank you! I tried to make it as simple and easy as possible.
No I haven't really. I guess I went with the water method because it's less messy and I know it works. What are the benefits of using oil? I would think the oil would also smell really bad as it burns off. I guess the oil would not evaporate so the mold would be able to sit around for a while before casting without drying out. You can see one of my newer videos where I did a simple casting with this sand: ua-cam.com/video/z-OP4EIhGWI/v-deo.html Thank you!
Its an american thing
another one is
al·u·min·i·um IUM
not "al·u·min·um"
Very cool! I wanted to try this sometime soon, really handy! Greensand is almost impossible to get, and if you can get it, its way too expensive. Bentonite clay powder is also very expensive, so this is my best bet I thought. Nice explanation about the litter, have to look carefully which one to get. No cat expert :P
+Triangle_DIY Yeah you have to get it from a casting supplier which are really hard to find. So this was the best and cheapest method for me. Good luck!
I sourced mine from a well drilling company 20 or so bucks been awhile co-op has it I think it's in pellet form they use it as binder in some feed and for sealing ponds that will not hold water
Bentonite clay is ridiculously cheap
Great stuff! Thanks for the tips 👍 though I think I am going to buy a bag of 25 kgs bentonite clay instead 😁👍👍
thank im try it out
What if you used oil instead of water?
hmm, you should try using "moon sand" for casting and see how it goes :D
+TheFugiapple12 I though about that actually!
Bentonite(just coz it bugs me haha), also you should do an in depth vid of your internal combustion engine! I wanna know how you did it lol
+jam9297 The video are coming! I have some videos that lead up to it that need to get posted first! Plus I need time to edit all the videos!
+jam9297 LOL yeah my pronunciation isn't the best!
seems like there is some water content in the kitty litter. maybe it wouldnt cake up if you oven dried it first?
+ironlionkalo That's a good idea!
+Clanner Jake Yeah I had thought about cutting a hole in the paint can and covering with some screen. Then anything that hot ground small enough would exit. Good idea. Someone else actually just sent me that exact same video! I am thinking about making one using that method. All though I would not go the the extent he has with that complicated mold and everything. I'd probably just form it with my hands.
+Clanner Jake I'm considering making one using a method like one of those. I'll certainly keep looking into it! Thank you!
Wow that castle they are building is awesome! They started to build a similar one in the US but it seems they have stopped because of financial reasons... seems ironic considering they are doing it off the land... I guess the workers are not volunteers. I have forged a couple of knives! It's a lot of fun but it sure does take a lot of work. About 3 hours for me since I'm a noob. I need to post some videos on it...
i would suggest that you weigh the sand/clay/water before you start mixing and after you finish mixing a perfect batch and you will have your own 'calibrated' ratios. then test that ratio on the next mixing.
once you have that ratio worked out, if you have the (jerry rigged) ability, set up a bigger ball mill to mix the the green sand with you new ratio's. just dont add the water all at oncd (to prevent clumping. lol)
+Randall Lasini That's a good idea! I guess I'm generally not to scientific about things. I just kinda mix things and see what happens... But I will do that when I mix up some more! Thank you!
I can't get mine to work. Whenever I lift up the frame everything just falls apart. Any thoughts?
+Zac Shaheen sounds like a few things could be going wrong. Could be too dry. Could be not enough clay. It could be wrong kind of clay. Did you do the clay water test to make sure it's bentonite clay? How fine is the clay? How much clay did you add to the sand? How dry is the mixture?
Makerj101 thanks for getting my back to me. the clay is bentonite, extremely fine. Is it possible to have too much clay In the mix? also is it possible to have it too wet? one last thing. I am using a 2x4 with a box about 3 feet by 4 inches, I don't know if the dimensions of the frame have anything to do with it
+Zac Shaheen more clay makes it hold together better. However it clogs the pores between the sand which doesn't let steam and other gases escape which can cause issues when casting. It could be too wet. Does it comp together when you press a handful? Does it break cleanly? Hmm 3 foot is a pretty long frame. The boards could be flexing which is letting the sand fall out. Try using a router or circular saw to cut grooves on the inside of the frame to give the sand something to hold onto.
Great advice! Thank you
Let me know how it goes. If you still can't get it to work properly make a short video of your sand and I can take a better guess at what is going on.
aw why dont my one look like that???
Re-Chris Jones comment on pronunciation of BENTONITE. Great video.
who is Chris Jones?
I was able to extract clay after boiling it in water.
Yes please it’s bentonite. Ben-ta-nite. Pronounce It ben-tá-nite or Ben-toe-nite not bentanyl.
BUT SUPER VIDEO AAA+
I think you can get bentonite from farming suppliers.
+Courtenay Blackburn (Libertarian Socialist) You're probably right.
Why not just use a scale to try different ratios?
How to find Your mix ratio? Start with exact known amounts of sand, bentonite and water. Make sure You do NOT spill anything on the floor or elsewhere. Once You find the magic blend, just look what is left of what You started with, and You have Your ratio right there.
BTW, take some time to study videos of molten metal exploding in moist environments. You may want to refine some of Your working methods, after seeing how dangerous this really is!
But a blender at Goodwill for 2 Bux.
+73turbopinto That was the other thing I thought about doing.
actually not a bad idea!
+Triangle_DIY All the gravel would get ground up with the clay and I wouldn't have to worry about sifting it out.
+Makerj101 I use an old coffee grinder (good will), it turns the litter to fine dust pretty quick, I did a 20lb bag in bout half an hour, worked great
larz0001 I'll have to look for one of those. I've seen other people grind some pretty weird stuff with them and they hold up really well.
It is BENTONITE. Not BENTINOTE.
ben-toe-night
Drilling mud
Your water experiment doesn't determine if it's bentonite clay or not. It determines if it's calcium bentonite or sodium bentonite. Calcium doesn't expand, sodium expands .
Ugh. bentonITE, not bentonOTE. Yer killin me.
It's pronounced "Ben-toe-night"
Where is A Next part ?
its pronounced ben-to-night
are you a boy or a girl
he's a boy
He sounds like a little kid
Hey it's bentonite clay not Bent-a-note clay that pronunciation is actually ridiculously annoying
