Step 1: Basics of Sand Casting

Sand casting is a process that uses a mold made from either metal, wood, or wax to create a negative impression in a special sand that will be the mold for the molten metal.  This mold is then filled with a molten metal that is left to cool and solidify. Once the metal has solidified the mold can be hit with a hammer, pipe, or any hard object to crack the sand mold and expose the metal object. 
a simple way is a screen from a screen door to check 4 unwanted items.
or old soda cans. if yr over 21 yr empty beer cans. or u can get them from a local park. i love trash can diving tho(wear gloves, the good kind with long sleeves if u can afford them) and anti germ wash to wash yr hands an arms!!!!
got it. also yr local vacum repiar shop an bike shop are great place 4 scrap metal . also be kind to the employees, even if yr having a bad day. remember this they will remember wat u did. and that source of free metal will dry up fast.
This studio looks like where I studied sculpture in Little Rock.
Just a quick terminology correction: A <em>mold</em> is a negative image, like your sand. The object you are using as a stand-in for the final object is a <em>pattern</em>.<br> <br> In lost-wax casting, you can use a resin mold to create multiple wax patterns. When you invest the pattern and burn out the wax, the casting flask itself is also a mold.
I remember hearing that there is something that can be applied to the negative to allow the sand to more easily come loose.... wax or cooking oil? not sure if I missed it, but what additive is used to facilitate the mold hardening?
This reminded me of doing this in 9th grade shop many, many years ago, and I've wanted to try it again. &nbsp;Thanks for the inspiration. &nbsp;But as I remember, the very fine sand--almost like powdered &quot;dirt&quot; in consistency--was a barely moistened mix of sand and water with something added to the water to make it sticky. &nbsp;Then we'd add sand and pound it in place so when the upper mold was taken off the lower, the sand would not fall out [at least after a few tries]. &nbsp;Are you using dry sand or adding something to it to allow it to stick together in the mold? &nbsp;Source for your sand? &nbsp;Did you dust the mold and the separation area with talc or chalk to facilitate separating the mold halves? &nbsp;How did you remove the original model and leave the central sand core intact? &nbsp;
How does the sand solidify by just sitting for 40 minutes?
I'm curious about the sand. It's not regular silica sand, what do you use?
This video is private?
Sorry about the video mishap, it was showing in the editor but got lost when I published. Seems to be working now thanks for the notification.
make sure the coat is leather or a heat resistant materiel. not some cheap cloth type!
here where very heavy gloves will come in handy. I.E. high quality stick welding gloves will work in a pinch also use a remote temp senor unit as well. or if u wanna use the heat cumin off to charge those batteries use a thermal electric generator of some kind
i.e. best to wait a day or 2 if yr not in a hurry. if yr in a hurry then wait 4 hr.s or so
un i think u 4 got the video
