I don't think I can express how much I appreciate having your knowledge documented so thoroughly on this platform. Thank you very much.
He can convey so much more information than many other RUclips contributors with all of their constant talking.
he is the Gigaluminum
I always think of my father when I see Myfordboy find other uses for common items that most people would discard as trash, e.g., cutting a plastic milk bottle to make a funnel. My father grew up poor during the Great Depression and never let anything go to waste. He always insisted, "I'm not cheap, I'm frugal. There's a big difference."
Extremely impressive stuff. I love the combination of old fashioned techniques and trying to improve that process with modern techniques like 3D printing. Very cool. Casting is definitely a skill I want to pick up later.
Your castings are always so clean and crisp!
Thanks for taking us along this time. (Can't wait to see the Sterling completed)
You definitely know what you're doing, that was a great looking casting.
Just done my first casting. It was only a sand rammer in brass, and came out a little on the rough side (think the sand was a tad too wet!) but I was still happy with the result. Just wanted to say thank you as your videos have been a huge help. Keep up the good work.
Ive never actually done a hot casting but I heard moisture in the mould can cause steam pockets
@@tommothedog It's my understanding that green sand uses water as a binder, unlike Petrobond which uses oil. I've seen a few people poking small vent holes into green sand to vent any steam pockets, but this seems to be done on larger castings. I'm sure the more I get into casting I'm going to run into these issues, but one bridge at a time lol.
myfordboy did a video awhile back which included sand prep and core making, if you've not seen it it's well worth a watch
ruclips.net/video/l3opkzAvVQk/видео.html
Oh man...can't wait to see the machining and final build!
So cool! Keep em coming!!!!
Fantastic. I have been watching your videos for a few years and you have a meticulous process. Thank you for showing us how to do it the right way.
just grabbed some of that green sand for my own little baby furnace. Managed to cast some tiny brackets with some 3D printed templates the other day as my first casting project! Cheers for the inspiration and info!!
It is incredible getting to watch a master at work. Great job man
Hello from France !
I watch your videos with passion, you do a wonderful job!
Thank you for sharing
I am in such awe of your talents, I've been wanting to do a 3D printed sand casting of an intake manifold for a small 4 cylinder engine. Just need a bunch of great tools like you have, and of course some of your talents as well.
Very nice work. N
The finest casting I've seen in YT. Felicitaciones desde Andalucía!
Great job casting friend!
Thank you for sharing your knowledge for the younger generation. I really like this trend of old timer showing us the world in their trade. No knowledge should be lost, only transfered
Sorry my previous negative comment was meant for someone else
I really appreciate yours.
@@myfordboy hahaha that simply made me laugh out loud! It was VERY obvious it was a mistake. I have a 3d printed and my friend has a foundry. We've been wanting to try lost pla casting.
Nice move actually incorporating the gates into the print!
I foresee a lot of request for castings, very impressive work. :)
This is just amazing work, AND so concisely and clearly demonstrated. Thank you. Based in part on your work and Veg Oil guy, I put together a prusa printer kit last fall, and have been learning cad. Next step for me is to work on a burner and forge. Then I'll have a hand at trying out some of this casting stuff myself.
I absolutely love your videos you are amazing and very talented I've learned so much from you and your videos. Your so knowledgeable
Good stuff as usual.
You've got great talent.
At last, back to the original theme! Good to see again quality content instead of TV-shop ;)
Very informative! Thanks.
Amazing work! I hope one day I can learn how to do all of this!
Pretty awesome
I hold the text down with the eraser end on a pencil and let superglue wick underneath to bond it. Nice job and video!
Very impressive.
Awesome!
Very nice work
good work
I made aluminum parts for a bamboo byke (the junctions) with the same technique , and I was thinking of making a Stirling engine to generate electricity, a reservoir with hot water (heated by the sun) and another reservoir with cold water. Very good project, just a quick note, it's a shame RUclips only has 2x speed.
Nice!
Pro at work
Wow I never knew the sodium bicarbonate trick, thats really neat
Carbonate not bicarbonate.
Using carbon dioxide to trigger the sodium silicate is freaking genius. I mean I know it would happen naturally when it's exposed to the air for so long, but accelerating it like that was genius. Now I'm going to have to ape you. 😉
Capo.!!
I've seen many tools come and go on this channel, but the green and white shower curtain remains unchanged. It's like a magic carpet, lol
Actually it's a tarpaulin and it has been replaced several times!
As soon as I saw those fins, I knew it was going to be a Stirling engine. Nice job.
Did you spot I used your 3D printed text, scaled 40%.
I put a link in the description.
Man I'd love visiting you so I could taste that delicious-looking brown sand because it looks like a tasty chocolate powder!
Boom in at the top
Hi buddy been loving your videos for so long now and it just dawned on me whether you are a fellow Black Country guy
South West.
@@myfordboy I thought you were down my way 😊
Man, I have so missed these casting videos! Did you see the momentary reflection of Myfordboy’s face on the inside of the measuring spoons? No? Me neither..still, I live in hope..
The metalsmith and foundrymen in Pakistan and India don't flux or degas, when they pour, they simply hold back the dross, I guess it performs the same function, but then I don't see you tamping down your core-boxes whilst barefoot either, so each to his own I guess.☺
The stuff from India and Pakistan is probably not as high quality and probably has bubbles in the final product. That would be my guess.
👍😎👍
What can be done to remove/reduce the small casting defects such as those directly above "KYKO" at 24.55? Great video. Thank you.
That will be a bit of loose sand that fell into the drag when the flasks were closed. Not an issue here, filled and painted.
Looks like the casting turned out well. I had wondered when you just dompted greensand on the mold and how good it went between the fins. Surprised the 3D software did not allow you to put the text in the print. Extruded text can be done in Fusion 360 as I have done it. Every time I see a casting video makes me wish I had the setup to do it but at 73 think it is too late to start.
I could have added the text and the gating in the CAD but was expecting to sand the print a little. The text would have made sanding more difficult.
It's never to late.Go for it.
@@myfordboy Looks like the quality of the print gave you a pretty good finish on the casting. The pattern sure seemed to come out of the greensand easily. Nice work.
Now you just need to design a cover for the moving parts, and then print it in clear resin.
I look forward to videos like this :). What does the tool at 21:00 do? Is it simply to ensure the sodium carbonate gets to the bottom of the liquid metal? And what do you do with the dross? Many thanks from Canada!
The sodium carbonate is put in a little foil packet and plunged to the bottom of the melt. I hold it there until it stops bubbling. Dross is discarded.
You are very exact in measuring the sodium silicate. What happens if you add too much? Or too little?
Too little and it wont hold together. Too much and hard to break up.
try acetates or sulphates then electroplate to a 3d printed mold (fill-in, instead of coat, from outside, with a seed start)
crank up the amps
any metal, in electronegativity order
⭐😃👍
I have to wonder.. Why not make a extruded aluminum frame. Something that either the flask sits on firmly, or the frame attaches directly to the flask. Put some guide rails on it with a gantry as well. To the gantry attach a base of sorts. This base can by rather thin and hook directly to the lifting screws on the pattern, and since it's constrained by linear rails, you can lift the pattern straight up out of the sand. So "fewer" worries about the hand shifting a tad and knocking over a fine detail? I dunno
Maybe when I am old and my hands shake but for now it's not an issue.
What kind of core glue is that?
Is that a special glue?
How long does it take from lighting to pouring the melt?
Core glue www.artisanfoundry.co.uk/product_info.php?products_id=42
About 20minutes from cold to the firts pour, less for subsiquent ones.
MONSSSTTTRRRYUUOOOO!!!!!
@myfordboy I haven’t yet tried casting but was curious as to why you didn’t seem to tamp down the greensand in the upper half mould?
It was tampted down same as bottom flask. Video was edited as I had already shown this.
@@myfordboy thanks
Well done! But never fill a mould until you are sure you have enough molten aluminum to fill the part completely. Casting will be scrap. Greetings from Germany, Stefan
I don't understand your comment. Plenty of metal to fill the mould.
@@myfordboy I mean scene at 22:39. There´s not enough metal to fill the form entirely. Best Regards Stefan
@@pulsorohr Casting came out fine although the feeder did not completly fill there was still plenty of head.
One of my favorite parts of backyard casting is eating and drinking whatever is in the containers we use for funnels and mixing containers or use as raw materials.
How to melt iron
Hi nice work, just wondering why you glued the text rather than intigrate text within the cad design ?
I was expecting to have to sand the print a little and it's easier without the text.
@@myfordboy Thank you for your quick reply, great work cant wait for part 2 cheers
Nice trabaggo can you tel my how the % is between the silica sand and the sodium silicate ? thank you
20mL of SS to 1 Kg sand.
23:20 is how my scones come out of the oven ...
really interesting, can I ask you what material does the inner souls make?
Inner soul?
@@myfordboy yes the internal sand cylinders
Do you mean the core?
@@myfordboy yess
The core is made from sand and soduim silicate as shown in this video
ruclips.net/video/CTfYNZhOyRc/видео.html
I have a question.
I wonder how long it takes for aluminum to melt.
About 20 mins from cold for that crucible fue using oil as fuel.
@@myfordboy Thank you so much. :)
thanks for sharing, what cad software you use?
It's ViaCad.
At What temperature did you pour?
About 720C
hello what ratio sodium silicate to sand do you mix. cheers
25ml to 1kg sand.
@@myfordboy cheers for the info
Where'd you learn to do all this?!
Self taught from books ( long before RUclips)
What is a casting sand granules size for good quality ?
I don't know what the grain size of mine is but it is very fine, like dust when dry.
How degrees do you use sodium silicate?
Add when metal is ready to pour.
Question: What is core glue? Thanks!
www.artisanfoundry.co.uk/product_info.php?products_id=42
@@myfordboy Thanks!
very nice, but why the vent holes at the core? Looks like it worked but why not at the highes point off the cylinder?
It's to vent the core not the metal.
doesn't that powder cause cancer?
What is the purpose of pressurized CO2? I know absolutly nothing about making sand molds.
It reacts with the sodium silicate and hardens the core sand.
@@myfordboy Thank you!
Where can I get files for this?
I don't have plans to make the dsing available. Just too much work drawing plans.
What/who is KYKO?
Google kyko fan.
hy .... please , can i find " core glue " ??? sorry for my bad english
joel
ok , I find alone with GOOGLE !!! lol !
I only have a link to a UK supplier that I put in the description.
youtube turned me down to sometimes noti's 🤨
Very good. Only get rid of the slow-motion video and it will be perfect!
