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.
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."
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.
@@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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-l3opkzAvVQk.html
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
@@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.
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!!
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
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 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 RU-vid only has 2x speed.
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. 😉
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.☺
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.
@@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.
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
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..
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.
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.
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
