How to make a green sand mold using a loose piece.

I need to buy bulk of resin at Home Depot but dont know whats a good easy resin to work with for begginers thats cheap for a lot of it and what silicons are compatable with these resins? I want to re create a shape over and over again with silicon. Remember i want to but a lot for cheap but need something durable and that has a hard cast not gooey at all when dry.

Making my own foundry furnace at home for melting aluminum. I came up with this design based on what i’ve seen others doing on You-tube, both DIY and pro guys (especially Tubalcain). I’m a firm believer that you get out what you put in. This project took about 6 weeks of part time work to do. Nothing was outsourced for fabrication. Everything was designed on the computer first. The acrylic brick moulds were made in one of the shops I regularly deal with that has a CNC. This furnace was designed around the need for single person operation and portability. I also had large reservations about casting the refractory cement (which is very expensive) in one piece. This would have also made the finished furnace body unmovable by one person. Casting bricks also allowed easer/effective/controlled construction and assembly. This also makes it very easy to dismantle and clean the unit. This has also been designed for possible production, so anyone with a marketing saavy that finds this interesting should contact me.

In part one he made the sand mold.  Now I melt metal and complete the casting.

Part one shows how the mould is made and in part two the metal is melted and poured.

Hello,

Welcome to the Metal Casting seven-day E-mail course.  Today you are
going on a journey.  You are going to learn about the basics of
Metal Casting.  I hope you are as excited as I am about this topic.

Here are the things we will be covering in the course:
What is Casting?

Lost Wax Casting
Casting Sand
Crucibles
Casting Furnaces
Next Steps – Casting Organizations

Lets get on with Day 1 of the Course:
What Is Casting?

Metal casting is an ancient technique that has a variety of applications and
purposes. Civilizations from the dawn of time to present day have used metal
working as a way of creating artistic, religious, and practical items.
The process of metal casting involves melting metals at high temperatures
and using molds to then shape the metal into new items. The furnaces used in
metal casting helped pave the way for the Industrial Revolution, without which
the course of history would be dramatically different. Metal casting is
just one form of metal working that has seen a recent surge in popularity as
resources are becoming more affordable and communities are springing up to
share information, ideas, and projects.

Metal casting requires specialized equipment, knowledge, and some creativity.
While metal casting is used on an Industrial level as the process cuts cost
and proves to be highly efficient, many individuals participate in metal casting
as a hobby and in artistic endeavors. Many people are drawn to metal casting
for one reason or another, although there seems to be two main motivations
that stand out. The first motivation that brings hobbyists to practice metal
casting is need; people may need to create items or parts for other ventures.
Metal casting is a great way to build hard to find pieces for models,
restoration projects, and even just small replacement parts needed for
common household items. The second motivation for using metal casting is
using it as a way to create sculptures or other artistic endeavors.

Whatever the reason, small scale metal casting is attractive because that
it can be done right at home, either in the backyard or workshop.
Individuals working in metal casting are able to create home made tools
and equipment like furnaces and molds. Metal casting is only limited by
the individual’s desire, so for those with the time and the need, virtually
anything is possible.

The actual casting process in metal casting has several forms, the most
popular being sand casting. Sand casting involves creating a mold from sand
which can be created at home, and then pouring the liquid metal into the mold.
Afterwards, the metal is allowed to air dry and the mold is removed.
This type of casting proves to be the most economical, but other types of
casting can provide fuller detail and higher quality results.
