The EASIEST Method for Metal Casting (open mold)

Open mold casting. The easiest way to sand cast anything. The best way? not even close. Nothing great is easy. Otherwise I would be an Olympic gold medalist. And they don't count gold foil covered chocolate medals as official. I checked.

Jewellers sometimes use cuttlefish bones for casting. They're made mainly of calcium carbonate but the structure is soft, you can press the pattern directly into them.

Those bubbles? That is why a pouring basin is used. The Aluminum alloy used for beverage cans is a 3000 series and does not make a good casting metal.

I love your self-deprecating sense of humor in all of the videos.

What I found with flat casting is to make a cover to go over the cavity. I took a piece of MDF; drilled a hole through the Center of it; then used a chamfering bit to creat a funnel. Then I cut it in half. Then placed the 2 halves together over the cavity. Lightly clamped the pieces down over the cavity. Did the pour until the molten metal rose into the chamfer. Waited for the metal to harden; pulled the two pieces off and with pliers lifted out the casting by the chamfered plug. With yours make the top pieces out of some type of metal, I guess. I’m casting pewter with mine; over a Smooth On flat mold.

Rotometals shirt for the win. Have been using them for decades now... I feel old suddenly. Time to light a fire!

1:53 MAKE SURE you sand smooth your 3d printed "drafted" sides, otherwise they'll still grab sand. Notice the ringing in his print, that needs to be SMOOTH.

Thank you for all the advice! Just got some from that company. Wicked fast shipping.
This will be perfect for making replica hardware for my antique steamer trunk hobby.

We used ladles in the foundry. Pour slowly but steady from above. Have to have a vent and srop when you see the pour opening and vent filled. Make a board. or metal top plate with your holes since you cant make a backside sand mold

Theres a movie replica badge I purchased that is out of resin. Is there a way or place to go to get it recreated a little larger and out of metal?

Poor Martian. Doctors think it's a physical problem, in truth he is just watching Paul pour castings. Even the ones Paul doesn't film, Martian can feel it.

I'd like to see the results you get if you use that zinc alloy in silicone molds

[MetallyCorrupted]

Very Cool! I just started playing with sand casting, Great tips

[steverenken]

I was thinking of doing something similar with some cookie tray trains using plaster of Paris to make a positive cast.
But instead of covering the whole back side, I was thinking of using tuna cans filled with sand just to cover that area, and dig the channels, and build up the poor, and exit holes on each side of the can.

why do I feel freaked out that at 3:04, has my hometown water tower?

[DavidClunie]

Any reason not going with a silicone mold? Especially if using a low temp metal. Back in the day I used to use RTV engine silicone from the automotive store but that hit took forever to dry, until I found tin base and then platinum based silicone rubber.

[sammaldonado]

ah yes, metal casting videos in the morning!

[joell]

Interesting. Nope, I won’t be doing any open mold. Thanks for saving me some time 👍😎👍

Why do I love make open mould castings - When I am making billets to feed my lathe and my mill. Not looking for fancy surface finishes or detail etc, just want a billet of metal to machine. A 100mm of 80mm diameter aluminium from my nearest metal supplier is about $50 delivered... shove some cans into some green sand, fill the resulting holes up with aluminium and I am good to go for a fraction of the price.

Hi, I'm new at this and this is a bit off topic but I'm hoping you could answer me. Is there a way where I can make a temporary sand or plaster mold to cast a strong metal like (steel or graphite) and use that to make a permanent mold where I would later cast other metals with lower melting points and not need temporary molds anymore?

[richardepps]

When will we see more of the David Gingery series?
