"A man who works with his hands is a laborer. A man who works with his hands and his mind is a craftsman. A man who works with his hands, his mind and his heart is an artist." St. Francis. Great video.
This is a beautiful quote. It's now up on my handwritten motivation board. It also reminds me of my lecturer's book: "RARE Total Leadership: Leading with the Head, Heart and Hands " Dr H. Ngambi
I'm a engineer at an iron foundry. But I'm tryna cast some stuff from home and your channel is so beneficial to me right now lol. W casting. W channel. W person
Thanks for this video- all these years later it is helping folks out. Prepping to teach this process in a sculpture class- and your video is clear and direct and informative. Thank You!
its really surprising how much better your pours are for objects with fine detail. That attention to the sand you make really is quite a good result! thanks for sharing/passing the knowledge on!
Makin Sumthin From Nuthin Yes! I watched the in reverse order...Greensand video first then this casting. You've certainly a detailed, knowledgeable channel! I feel you're "head and shoulders" above other similar content posters. I wonder if you could share some knowledge on casting "shrinkage"? I have heard it discussed, but never really seen anyone detail what it means. It seems important for things like precision casting. And your castings are as precise as I see out there.
Thanks!, most of my castings are not critical so I tend not to worry about the shrinkage rate. I machine most of the stuff I cast nowadays so leave xtra knowing it will need to be machined off. If you google "casting shrinkage rates" you will find a wealth of info on the subject. They even have special rulers made just for patternmakers that already take into account shrinkage rates for various metals. They all have shrinkage rates that differ.
Hi Mate another top job, i love your vids and what you produce. Another good thing is that you reply to as many people as you can. Keep up your great work....all the best from OZ.
Glad you like them! Too many TH-camrs do not reply to the people that take time out of their day to watch their videos....I decided a long time ago I would NOT be one of those people. Most get a reply within 15min :)
Well, here I am bud as promised. I really like your casting box. Well thought out. From what I see here the pour is great. Nice definition and very little flash. Well done my friend !
Thanks Much! The crucible was made from a fire extinguisher. It was the one I made in my video called POOR MAN's CRUCIBLE if you want to check that vid out, it shows ya how to make your own crucible. Consider subscribing if ya havent already! :)
would the casting technique the way you are doing it be the best way to cast a mailbox door? it is super simple and flat (less than a quarter inch thick) on the inside side of the door so do i need a two part mold like oyu are doing or can do i do something simpler? i read down in the comments that if i just used a one sided mold the surface tension would make it rounded off.also did you make the wood box for the casting? thanks so much
Sand casting would be an excellent way to make that. Yes I would cast one exactly as demonstrated here. If you did an open pour mold (1 sided mold) the top would be rounded for the reason you stated (surface tension). I have videos on how I made the casting flask (boxes) as well as a vid on how to make the sand :)
Hi from Tasmania Australia. Just setting up my foundry (73 yo learning something new) trying to learn as much as possible from a place that is a bit isolated from help.. Your video plus the one on making green sand is the best so far. Do you have any videos on casting bronze or brass as I make model steam engines and have gone into foundry work to get my hard to get & expensive roar material. Kind regards Mike
I was wondering if you could answer a question for me, could you do the same thing with an open face casting but still have a channel for it to flow into the mold so it doesn't destroy the finer details or will it not cast as well without the top box?
I attempted just that with limited results. A Megalodon tooth. Aluminum has a lot of surface tension, it wont make a flat casting without the other box
I bought a plastic plaster mold, cast one in plaster, then used the plaster piece as a pattern. I got the plastic mold online somewhere...cant remember exactly where
I looked at other videos that just used plain sand to cast coins and they looked pretty good and wasn't even close to being as fine as your's was, so I am definitely going to try making some coins out of gold or silver. I hear you can tumble them to shine them up. I will practice with aluminum first then go for some gold or silver thanks
where do you find the original statue for the mold? What material is the molding statue made out of? because I would like to do the same thing but I'm unsure of how much or where to spend on a statue just to make the mold
Great channel. Even if I wouldn't be interested in casting myself (soon). That damn nice moment when you see how the cast turned out is very satisfying. What is this white powder you use at the start? Can I use normal cans for the alu?
Hi, its just regular baby powder I pick up at the dollar store. Yes, you can use soda and beer cans.....you get a lot of slag with those but yup you can certainly use them. I am glad you like the channel! :)
Excellent work and excellent video! Thanks for sharing! I have a quick question, what made you choose to put the sprue where you did? Would it not be easier to clean up at the end if flowed onto the back face?
It just seemed like an out of the way spot. Pouring straight down thru the back may have destroyed some fine detail on the front of the casting from too much velocity
I only have an older iPad2 to shoot these videos and it doesnt do close-ups very well. I wish I had better equipment to film my vids, maybe one day if funds will allow :) Thanks for watching!
What a fine detail job. As I mentioned I made a electric furnace with nichrome wire with fire brick a small furnace and I actually bought from China A 1 kg graphite Crucible I've reached a thousand degrees already and I've got to get a bigger variac a 20 amp I have right now at 10 amp variac and I can only turn it up so high before blows the fuse out and doesn't reach the temperatures for melting aluminum but with a 20 amp I can bring it up to 15 amps in the wall 110 volt that should give me the temperatures I need for even possibly melting copper
Sounds like you got a handle on things....thats terrific. For copper you want around 2100 degrees so it flows when poured. I have melted some in mine....takes its toll on the furnace tho. Glad you are enjoying the videos 😊
absolutely beautiful. you did an amazing job on this. do you think that green sand casting would be good to cast the wooden props I made into metal for cosplay, such as swords?
You put the vent on the part but the pour spout off to the side ? Any particular reason ? What happens to any trapped air pockets inside the part ? Does it vaporize into the surrounding sand ?
I have been saving propane tanks for making a furnace. I have the valves off and rinsed them many times with water. Would you say they are safe to cut with a grinder?
At that point I would say its pretty safe, looks like you followed all the recommendations I have seen prior to cutting. Have someone you dont like drop a match in it to be sure....(just kidding) LOL
sir please be extremely careful. I had a very dear boy almost blow his head off cutting a propane cylinder in half. he knew better but being raised like we were you say yes sir and get going. he was burned over 95% of his body. please becareful
I understand the dangers of it and have taken every precaution to insure my safety. I had a man working at the local scrap yard start cutting into a large tank that had not been prepare, it still had gas in it, It blew up and killed him instantly so trust me It scares me even though I take all the proper precautions. But thank you for your concern.
Great video, im impressed. Do you think greensand casting would work for less flat objects? Like if i wanted to make a hand from plaster into aluminium, could i use greensand?
Thanks! A hand presents a problem because with green sand casting the pattern used to form the mold (plaster hand) would need to have draft angles and no undercuts for it to be removed from the sand without disturbing the sand itself
With something like that it's probably best to make an alginate mould, which you can do directly on your hand or the object in question. Then you can pour wax or even some kind of resin into the mould. With the wax you could do lost wax casting, with the resin you can do sand casting. I've done this for lost wax casting.
I have a question about how to mold a part I need. I'm inventing a device for small outboard motor to use electric tilt and trim. how do you get the part made of clay or what ever to make the void in the sand? like the part you powdered and then removed. great work!!!!
The part to be cast is called the "pattern". Patterns are generally made of wood and painted to a gloss finish so sand wont stick to them. In this video I use a one sided pattern(one side is flat), my pattern in the vid is made from plaster so no wood pattern needed. For a part that doesnt have a "flat backside" a 2-piece pattern is used. All patterns must have proper draft angle on all exposed surfaces and no undercuts so the pattern releases from the sand easily without damaging the newly made sand mold....such as shown in this video. For parts with a hollow interior section a sand core is used to keep that section hollow, the core prevents the metal from filling the void
Makin Sumthin From Nuthin Are your pieces made of plaster? I'm getting too much to make my beautiful pieces of aluminum, my pieces are bad in the sand, I'm now making the silicone mold and then I melt the candle and burial in the sand, I'm on tests yet; his pieces come out perfect from the sand, congratulations for the work, greetings from Brazil, Antonio.
Hi, yes...the pattern used was made of plaster. Plaster is good material to use for a pattern if it is feasible, otherwise I make them from wood. Thanks for the kind words :) ~ Richard...Florida USA
This was just a one piece pattern so only the bottom box (drag) was used for ramming the mold. You could pour aluminum directly into just the bottom but you will get a rounded bottom to the casting instead of flat because the surface tension of aluminum is high and it doesnt flow like water and lay flat. Good question! :)
Great vid!! Do you use anything to de-gas the melt? How about flux? I de-gas with sodium carbonate and flux with common table salt. We both use the same ingredients for our green sand, right down to the brands, but you went beyond me by sifting the sand. I tried to make a clay slurry instead of blending ( blender burnt up) and the finished product looked like oatmeal. Some of my castings can get kinda big, so I keep about 400 pounds of mixed sand in sealed buckets. Because I work alone and some of my castings and molds can be heavy, I built a jib crane that swings over all of the casting stations. I also mix and freshen my sand with a "2 bagger" concrete mixer. My next mold will be made on my new ramming bench with a 4" thick reinforced concrete top.
Great video but I have a question that how long can we keep on using that burner or torch?I mean can we keep on igniting it for hours or do we need to give it a rest?it is dangerous to keep it on ignition for hours because it could get too hot or can we use it for as long as we want?
That came out great! The finish looks really nice.I noticed you didn't degass or flux and your dross was minimal. Was this due to you using ingots instead of straight from scrap? I'm also guessing from the shininess of the piece that your AI wasn't from cans or extruded scrap.
Thanks eviltwinx! It did turn out quite nice....that was my first casting with the new flask and green sand I made in my other videos so was a good day :) Very little dross was due to using ingots but most of my aluminum is scrap converted to ingots (car parts, cans, mower engines, lawn furniture, etc...whatever I can get for free!) I have about 150lbs already in ingot form and probly another 100 that needs to meet the ingot molds!
I dont see a noticeable difference in using degasser & salt flux so dont waste my time with it. I have had friends and customers machine down aluminum I have supplied and they state its fine with no porosity so I skip that step. I have done it once or twice to be fair tho awhile back.
Makin Sumthin From Nuthin Good to know. I'm still learning. I've fluxed but haven't tried degassing yet. I do get some porosity, but it might due to the fact I'm melting scraps and using the lost foam method - which produces a lot of vapor. Hoping to cast from a pattern soon.
Flux is supposed to make it more "fluid" from what I have seen/read, but if the metal is the right temp it flows just fine (as in this vid) so see no reason to use it. Give green sand casting a shot....its really quite simple. I have a vid on making the sand and that's simple too! The handles I made with the lost foam method worked sweet! :)
@@MakinSumthinFromNuthin I'm running the Devil Forge and I've never went that high. Does it make for a better melt? I'm about to make the green sand u showed on ur channel and see how it does. My first green sand made. It looks like it will work great!!!
Are u selling yr castings I have a wood cnc. And I can make my own mold of many things. With cnc I can carve anything I can get a pic of. I was just wondering if u can make money that way after all cost. With our current situation in the USA I'm looking for other ways to make stuff as wood carvings ppl are just not buying right now. I don't see it changing any time soon.
I have never tried to sell castings, I just did it for demonstration purposes. Castings I do which isnt often is for stuff I need around the house/shop. With the work involved it would be difficult to make a living doing "one off" castings
If you are going to make a video in an attempt to show someone how to do something and save them a lot of trial and error-------you should give them the correct directions. Otherwise, just keep the process to yourself. In your video, you show that you are using a bag of "Kitty Diggins" cat litter. It is available at Walmart for cheap ,so I bought 6 bags for a large sand cast mold. IT IS NOT THE RIGHT KIND OF LITTER..It does not CLUMP and it may not even Bentonite Clay. Clumping, Bentonite clay litter is needed and this Walmart crap does not work no matter how much you add to the sand. I bought the CORRECT type of litter and it worked. So...go figure.

Thanks, I appreciate that. This video shows the process but not of Guadalupe... th-cam.com/video/9Zj-WSa53kI/w-d-xo.html
Very informative video, thank you sir. Do you clean out the aluminum left in the crucible after the pour or does it not matter too much?
it usually shrinks and pulls out easily

Nice videos man. Have you ever done one showing how to make the burner for your furnace? Id love to see that.
Yes, I have a video up on the burner....not difficult. If you need further help after watching my vid let me know. Thanks!
Great video, where did you buy the flask from?
I made it, I have videos on making them

Liked the the video. Just wonder how easy it is to cast things that has small details like coin replicas? Really loved the video thanks for sharing.
The detail on a coin would be extremely poor in my opinion Steve. The sand grains are too large to capture that kind of detail

What is the powder you are using first? and what is the ratio of sand to water to kitty litter! Thanks
Just talc powder (baby powder)
clay/sand ratio I use is 11% clay to sand by weight. Water ratio you must experient with

Yes....baby powder, just get the unscented stuff, make sure it says "talc powder" :)
great video but i wish if you put the time in it. for how long you let it stay and cast.
Thanks.....if you could be more specific about what time frame you are asking about I will be glad to answer :)
What a fine detail job.

You put the vent on the part but the pour spout off to the side ?

Some people don't use vents, the sand absorbs the gases if mixed properly

Do you know any of the history behind the Our Lady of Guadalupe you cast? It was pretty interesting to me.
Sure dont, thanks for watching
What kind of sand is used and how to get it
one question
why you only sift the first part of the sand and not the rest?
Because the first part of the sand you reference is what is touching the front of the plaster pattern and provides a better surface finish :)
awesome I understand that thanks for your response
amazingly accurate :)
Thanks!, hope you enjoyed the vid :)
For the mold do you have to have 2 parts? I have seen people use only the bottom box. Why keeps you from doing that?
This was just a one piece pattern so only the bottom box (drag) was used for ramming the mold. You could pour aluminum directly into just the bottom but you will get a rounded bottom to the casting instead of flat because the surface tension of aluminum is high and it doesnt flow like water and lay flat. Good question! :)
Makin Sumthin From Nuthin I made a mold twice and it collapsed twice any tips?
Sounds like a problem with how your green sand is made. See this video I made on the subject th-cam.com/video/2rAQxw6X6uc/w-d-xo.html
Makin Sumthin From Nuthin I don't think it's the sand because it does the break test good but I could be wrong I tried 5 more times same result
Hmmm, does your flasks have grooves cut into the interior walls to provide gripping surfaces for the sand? I have a video on flask making
Great vid!! Do you use anything to de-gas the melt? How about flux? I de-gas with sodium carbonate and flux with common table salt. We both use the same ingredients for our green sand, right down to the brands, but you went beyond me by sifting the sand.

Great video but I have a question that how long can we keep on using that burner or torch?I mean can we keep on igniting it for hours or do we need to give it a rest?it is dangerous to keep it on ignition for hours because it could get too hot or can we use it for as long as we want?
use as long as you want
The offcut big unlike ours amazing
That came out great! The finish looks really nice.I noticed you didn't degass or flux and your dross was minimal. Was this due to you using ingots instead of straight from scrap? I'm also guessing from the shininess of the piece that your AI wasn't from cans or extruded scrap.
Thanks eviltwinx! It did turn out quite nice....that was my first casting with the new flask and green sand I made in my other videos so was a good day :)
Very little dross was due to using ingots but most of my aluminum is scrap converted to ingots (car parts, cans, mower engines, lawn furniture, etc...whatever I can get for free!)
I have about 150lbs already in ingot form and probly another 100 that needs to meet the ingot molds!
I dont see a noticeable difference in using degasser & salt flux so dont waste my time with it. I have had friends and customers machine down aluminum I have supplied and they state its fine with no porosity so I skip that step. I have done it once or twice to be fair tho awhile back.
Makin Sumthin From Nuthin Good to know. I'm still learning. I've fluxed but haven't tried degassing yet. I do get some porosity, but it might due to the fact I'm melting scraps and using the lost foam method - which produces a lot of vapor. Hoping to cast from a pattern soon.
Flux is supposed to make it more "fluid" from what I have seen/read, but if the metal is the right temp it flows just fine (as in this vid) so see no reason to use it. Give green sand casting a shot....its really quite simple. I have a vid on making the sand and that's simple too! The handles I made with the lost foam method worked sweet! :)
Like Number 1k 😀😁
That video has 1000 likes? Wow! 🎉🤗
new to pouring aluminum it's fun alot of work that people don't understand hahah
Yep, a lot goes into it in the preparation....pouring the metal takes just seconds! :) Consider subscribin if ya havent already!
Did u have the furnace at 9 psi?
Thats about right with my setup.....8-10 PSI works well
@@MakinSumthinFromNuthin I'm running the Devil Forge and I've never went that high. Does it make for a better melt? I'm about to make the green sand u showed on ur channel and see how it does. My first green sand made. It looks like it will work great!!!
Forges & foundry furnaces are a bit different, go with what works best. Good luck with the sand! :)
How long did it take to complete the cast from start to finish?
30 min or so from a cold furnace, not including making the mold
Great job! Would you be interested in casting a small item for pay?
Sure, but a lot depends on what the small item is and if it can be molded in sand. Email me a pic of the item at makinsumthinfromnuthin@gmail.com

Great video, Thanks. Be aware that the Teflon fumes are really toxic
Are u selling yr castings I have a wood cnc. And I can make my own mold of many things. With cnc I can carve anything I can get a pic of. I was just wondering if u can make money that way after all cost. With our current situation in the USA I'm looking for other ways to make stuff as wood carvings ppl are just not buying right now. I don't see it changing any time soon.
I have never tried to sell castings, I just did it for demonstration purposes. Castings I do which isnt often is for stuff I need around the house/shop. With the work involved it would be difficult to make a living doing "one off" castings
Teflon has incredibly toxic vapors. Glad you did that outside.
“Ora et labora” pray and work
sir ferr silicon is rock
I dont recall mentioning silicon in the video ?
little cheap funnel works better turn upside down put can over fill can
Yes, have seen Brian O. Use that technique, looks quick and effective 👍🏼
Good to see that the woodprix has new instructions to save my money and energy to build it.
Check my how we do it with brass
OldGuy like me would send ya to Mom to PUT ON your damn BOOTS !!
Do as I say and not as I do!.....WEAR BOOTS! :)
Makin Sumthin From Nuthin
add no damn STEEL TOED boots either !!
(smashed toes can be fixed.. AMPUTATED cannot)
Revelation 12:1
not roar but raw, brain not in gear :-)
never cast with bare legs, always be covered and wear boots……
If you are going to make a video in an attempt to show someone how to do something and save them a lot of trial and error-------you should give them the correct directions. Otherwise, just keep the process to yourself. In your video, you show that you are using a bag of "Kitty Diggins" cat litter. It is available at Walmart for cheap ,so I bought 6 bags for a large sand cast mold. IT IS NOT THE RIGHT KIND OF LITTER..It does not CLUMP and it may not even Bentonite Clay. Clumping, Bentonite clay litter is needed and this Walmart crap does not work no matter how much you add to the sand. I bought the CORRECT type of litter and it worked. So...go figure.
