I know I am a deity heathen for not knowing this. But, what was the point of the green sand in this? Why not A) build the ducts into the original plaster mold. Or B) just heat the mold and pour the metal in on top with a retaining wall?

This is rather clever. With investing casting generally the metal if forced into the investment mold. Either by spinning the mold while casting or sucked in using a vacuum. Placing the open top investment into the drag allows air to escape up through the sand in the cope.

This, gives little place for air to 'catch' and displace the molten metal. Most castings displace a significant volume of sand in the cope (for symmetric parts, as an example), that may trap air, hence the need for a vent.

It's more about the fluid hammer than the heat (the mold's already been proven at close to aluminum's melting point in the oven, and should be fully dry). Aluminum isn't dense for a metal, but it's denser than water - so when it drops into the molding height, it _hits_, causing the potential for erosion and/or cracking. The well prevents damage to the mold by absorbing that impact, and limits the inclusion of eroded sand into the investment.

@garywheeler7039

There is also a recent idea that ideally hot metal should come in from the bottom. This almost achieves that idea but keeps a more standard method of working. Doesn't require an opening in the bottom that would have to be cut either.

They all had some problems with gas as well as the aluminium sometimes cooling before it got to the edges of the mould. Each time the feeders went straight into the mould void. If we'd had larger and taller feeders that would have held the heat better and the weight of the metal in the taller feeder pushes more metal into the mould form? Is that what you've done here? Great video and cast by the way.

Really enjoyed your video. I remember during the late 80's when i was in Junior high we had shop class and learned woodworking, welding etc. This was demonstrated to us by our instructor but I never tried it. I have Adult ADHD (ADHD) back then, but that was when it wasn't even heard of. The point is I could not focus on things as paying attention to the instructor describing the technique or the type of sand. So I was apprehensive. Now that I self-manage my ADHD I look back and see how I did not understand, but yet when I was focused on something I liked, my mind went wild with it. Now I have embraced my learning condition. Not that this means anything other than the point that I remember this being done. To do this at home though. I would need a refresher and where to get the materials. Finally, with all the different casitng methods I have seen people demonstrating and talking about bubbles in their molds. I am thinking to myself. "Why are they not using a massaging vibrator to get the bubbles out. And you sir are the first to do that. Yay! Again, Great video.
