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.

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

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 kzread.info/dash/bejne/nmej0s2zcdm8gc4.html

I foresee a lot of request for castings, very impressive work. :)

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 hold the text down with the eraser end on a pencil and let superglue wick underneath to bond it. Nice job and video!

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 KZread only has 2x speed.

Man I'd love visiting you so I could taste that delicious-looking brown sand because it looks like a tasty chocolate powder!

Nice!

Awesome!

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. 😉

Now you just need to design a cover for the moving parts, and then print it in clear resin.

Too little and it wont hold together. Too much and hard to break up.

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.

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.

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 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
