Creating the Metal Foundry!
After a long delay, I finally managed to build my metal foundry. The design has changed a lot. I decided to use firebricks to create the housing of the force instead of casting one with plaster of Paris and sand. This would allow me to easily build and rebuild the foundry when needed, and expand it if needed.
To Build the forge, I used 10 Vermiculite firebricks, assembled into a cube to create an enclosed area. I also needed an air source to force air into the forge. To do this I used a steel pipe and a bubble bath machine, which worked really well.
For the fuel, I used regular BBQ coal, this worked okay but I need to experiment with other fuels. I Used a graphite crucible and tried to melt down some aluminum, and it worked!
