Making Aluminum Sand Rammers for Metal Casting

- In this video I will be using sand casting to make aluminum sand rammers. Sand rammers are foundry tools used to tightly compact the sand in a mold. I designed these sand rammers to be more ergonomic than the design I was using previously.

If you ever start a band, it should be called Seth Robinson & the Sand Rammers. :D Nice job. I've been enjoying watching your videos for a while now.
Haha that’s clever! Thanks, glad you enjoy watching them.
I didn't expect to find you on one of these videos lol
Sounds pretty gay to me
ive seen a pretty decent range of metal cadting content on youtube; this is by far the cleanest cast ive ever seen. no overflows, no fires, no bubbles, no lumps. clean, efficient casting and a gorgeous end product.
bravo.
Agree
After how many tries, we don't get to see ;)
It would be fairly easy to mill out a square void within the mallet head of the tool and pour in molten lead or bismuth, followed by a flat recessed aluminum cover plate hold in with flush machine screws. That lead or bismuth core in the head would make the blows way more substantial. You could also fill it with lead or bismuth shotgun shell shot to make it a "dead blow" type hammer. #7.5 shot would probably be good. :)
I wouldn’t have thought you’d pull out and replace the object in between the mold creation, interesting
Thanks you!
Yeah me either. Then it totally made sense.
I wouldn't have done it that way either, and I wouldn't of had to screw the board on either.
I wouldn't have used the half pattern at all, and did it with a false cope with the full pattern, which I've done before. A lot less work, but he did a very good job.
When the old rammers clock in at the office in the morning only to realize at the end of the day that the paperwork they were working on was their replacement's contract.
Thank you for making the stl files available. These are great.
Would love if you could do a video on all the different tools you use.
Since I'm a friend of Dorothy, I immediately laughed realizing that the ol' backdoor washout device could be repurposed into a casting sand mold dusting bulb. I love things that have dual uses, especially when both uses are very fun! 😸
I'm pretty sure that's a Giottos Rocket air blaster for camera equipment and not an enema. But they do look similar now that you mention it.
@@par5endos562 I guess I was a bit vague in my comment. I didn't think HE had an enema bulb in the video. I was just saying I laughed realizing that others could repurpose their own for this reason. 😸 Every good bottom has one, and they look basically identical. 😸 Also, I just realized that the little baby amniotic fluid nose sucker bulb thingy also could work because it looks identical too. 😺
Thanks for adding Celsius, makes it so much more interesting to watch
Relly? I dun think it does..
It does make the video more relevant, for those actually intetested in learning the process! 🙂
@@mariusmossum2923 but ppl who want to make it, they can just convert the nums, rel easy with google
@@JackTheAwesomeKnot even easier with it in the video -_-
Even though I'm not in metal casting anymore, it's still super cool to watch this stuff.
My dad used to say it's it's easier to to something right than it is to do it over. I like your method. Everything was clean and organized. You explained well and the video was nicely done. Thank you.
Good looking tools you made there. Nice, clean job. They look like a good design. Last time I sand casted was in middle school shop class in the late 70’s. We had big chunky sand rammers made of wood. Tapered on one end and flat on the other. They were all chipped up and nasty too.
Sand isn't the only thing you can ram with these tools ;)
Was the flesh-colored printer filament a purposeful choice?
You know it was.
Gotta have the right color for a rammer
Just the tip and only until the swelling goes down
This channel has to be my favorite. I've easily watched every video at least twice now. Keep up the good work.
Ah. Fancy. Long time ago i just looked around on the ground for something to use to ram- saw a chunk of 1×2 and 2×2, made nice smooth ergo handles on em with a belt and palm sander. Been using them for a LONG time😂 that and a rubber mallet for my final pack. Have a mold drying up a little bit rn actually going to go pour in a minute
Those look great! Thanks for sharing the files, too
You could easily get yourself some golf club grips and put them on the handles of your rammers. Would definitely be more comfortable than bare aluminum.
I'm glad the description said sand rammer, I saw the pick and realised I'm not well.
What happens to the petro sand that is burnt? Is it reusable? Do you mix it all together afterwards? Scrap it off and reuse the rest? Just curious. Wonderful videos! Keep up the great work.
Your tools and methods are so nice and well thought out
Those look absolutely amazing
Thank you!
Beautiful job on the rammers and the video. Well done!
Thank you!
As always, great work man! Keep the videos coming.
Thank you! I will!
Great content 👌
Very smart, only using one half to establish the parting line...
Thank you!
Looks great
Those are so cool and great step by step guide I learned a lot
These are beautiful
Very nice…great job!!
Your voice and video structure really reminds me of Grant from the King of Random (may he rest in peace) in his older videos from the mid 2010s
I'm impressed, good job. You might want to say why the spurs did their job, shrinkage. It can be seen in the spur, but not in the casting. I might make a pair similar, but not the same, because I like a different shape to pound with. Good job.
WOW you did awesoe.. and thanks for the free files .. :-)
Like they came out of a factory production line ! 👍🏻
Bravo Amigo! Great video...
Thank you!
Can’t tell you how cool i think this is. Thanks for sharing. (Came from functional 3d)
Thank you!
This is so satisfying...
Beautiful
4:50 in the bottom left corner. The plates of my childhood lol
Really really awesome foundry skill sir
Love it!
I still don't understand the false drag concept, but the large feeders with a relatively small sprue is genius, higher flow keeps the metal from cooling before filling the feeders. That is a really neat design!
Nice. Great job I love them
Very nice work. When making your models how did you slice the turnings into two equal pieces and how much distortion of the diameters did you get?
Hotkinkyjo be like.
Hotkinkyjo : Oh my, i need this.
Really needs to be longer for her taste
Have you thought about selling the rammers or your other utensils you use to make the spores and runners?
Perfect job. Very nice control when you poured because I didnt notice any air sucked into the mold.
Either way I still use my multi sand rammer 😉
Thanks! The pours did go very well. Waaay too much metal in the crucible though.
@@robinson-foundry for the first pour actually yes. The way I count my ammount that is needed for my 3d printed casts is to slice the part in slicer with 100% infill. Then the slicer gives you information about the volume of filament that would be used for the print. I just add to it about 20% for the sprue, runners and feeders/risers and I am ready to go 👌.
Try it with your next project maybe it will help a bit. Either way I must say this project of yours was still a success! Good job and keep it up 💪
I loved the Castings a lot ..Very Elegant design and Super accurate Metal solidification..I wonder How you managed shrinkage allowances .. Though you made huge Feeders.I still wonder..Osm work sir
So that thing is for pounding sand? Brilliant
Can also wrap some leather around the handles, or stick a bike handle on for some extra shock absorption.
Can you reuse the used sand?
Thank you for sharing your files for these, I am definitely going to make a pair. Do you know where I can find a crucible pouring handle like you have, I have a 10kg crucible that I use for aluminum and a tipping handle like that would be very helpful.
Thank you so much for all of your videos, they have inspired me, lol. I only have a 3 kg crucible, how much do I need to cast one of these at a time?
Flap wheels are a game changer. Material just disappears!
look good
I saw your post on fb group i am in. I jave been wantong to learn to sand cast as i am a medical and areospace engineering student, but funds are soooo limited. Anyway, do you have the STL for the rammer? I just built a prusa i3 from sourced parts and i want to test it with this file. Thanks
Edit..
Obviously i disnt listen to the end of the video haha
I have been looking for some good sand rammers, hope you don't mind if I print your design and make them on my channel? Great video.
Thanks! I don’t mind at all. Please do. I look forward to seeing them.
The flat one makes sense to me, but have you talked somewhere about why the pointed one?
I think the sand is a paid actor.
Could just use a shake weight
excellent rammers!
What do you do with the used sand? How do you recycle it? What can be recycled and what has to be discarded, if any of it?
nice plug
Can you reuse any of the burnt petrobond? Im assuming the black burnt parts are waist.
Well that's a ramming device for sure
You could just ad some tape for more grip, your work is still good
I'm wanting to try some casting. Where did you get your tongs for lifting and pouring? I seem to be only able to find the pliers type that you pinch the rim 9f the crucible with to lift it out of the foundry. The only pouring one's I've seen are the scissors type, I don't want those either.
check bigstacked on RUclips for making a set he shows how to make a set at home with no welder.
Those have the same handles as the usmc k-bar basically.
nice clubs
I would love to see how you recover the molding sand. You can't just throw it away, can you?
I need to be making spreadsheets right now
So you sand cast a sand casting tool
Y acá estamos...
What sand do you use for casting?
Can you reuse the burned sand or do you have to add new stuff after casting?
So the difference between this and the aluminum meat tenderizer in my utensil holder is what? Bet there's a price difference.
Why not make two halves and use pins to hold both halves together when ramming up the other side? You had holes in the halves that could have been used for pins.
Looks like a lot of work the way you did it, even if you did use a split pattern.
Sensual though it may be, the handles remind me of WW2 daggers. I wonder, would you try making a knife with a cast aluminum handle. This was not uncommon at the time!
Do I need to become a Patreon member before I can get a copy of the print for the sand rammers. Thanks Rudy
Your have taught me a lot, As I am person of Color in 1880 high school didn't give f8K.
damn i wish i was sand so bad 8-)
What did you use as parting dust? DE?
He usually uses baby powder
1:34 Ka-Bar tactical sand rammer
Do you ever accidentally hammer the wooden frame and mess up the whole assembly really bad? I ask because that's what I think would happen to me all the time and it looks so casual when you do it...
how did the metal reach the circular bit where your hand is stopped? I thought there would stay an air pocket
The sand is actually very porous so gas can penetrate it eliminating the need for vents in many cases.
I am confused, why did you put the half printed in? What does that do to help the sand form to the object?
He needs the two halves of the sand mold to press together with a perfectly flat and even surface at the center of the mold where they close together (or else you get a sharp seam where they closed together). The easiest way to do that, would be to just put a flat bottomed half model in the bottom of the sand container and pack the sand over it, so it becomes the right shape when it's flipped over and you don't need to worry about extra steps packing the sand specially for it. You can't do that with a fully printed model, and you shouldn't put a full model on the top and pack around it because it would not pack well without shifting and no amount of careful packing will leave the top smooth.
Why the 2 different one and why not just the flat one?
Do you just scrape off the black sand and reuse the rest? Or does it all go to waste once you add heat to it?
The burnt black sand is separated from the red sand. The red can be reused without issue. The burnt sand can be washed and retreated with the mold chemicals but usually gets discarded
@@danhammond8406 okay
I usually keep my hands 6 inches from the tip too.
Yes, "sand rammers", exactley what i thought when i saw the thumbnail
Seth, I love the content, but I'm 1 minute into this one and the wife and I have said "that's what she said" about a BAJILLION times.
“I’m one minute into this…”
That’s what she said.
@@soundmindtv2911 🤣
2 ways of using this you can use it for the sand and for you to
The second I saw that I thought those are some weird shaped butpluggs😅😂
I can't be the only one looking at this extended ultra heavy dido buttpulg am i?
Yes, sand rammers, that's what I thought they were, nothing else, especially not something inappropriate...
RF. Rat Fink. Coo...
Литниковую систему, рассчитывать не пробовал???
Other than the concise voice-over, great editing, and flawless casting, that banjo was simply the cherry on top !
Edit : chill banjo @ 6:30 :D
And its ribbed, for your pleasure ;)
Is this farcry 5 music?
Any Kleschguitars fans recognize the music lol
