This video shows the process I go through to make a mold suitable for casting an 18" cast iron parallel/prism/straight edge of my own design. The flasks used are cast aluminum and were cast in my foundry. The patterns used are 3-D Filament Printed.
Use of green sand for molding and a pneumatic rammer are discussed. I also show my shap-made remote control foot-pedal hoist and shop-made draw spikes and use of a bar to aid in accurate removal of a pattern from the mold. Risers and a ceramic filter (silicon carbide) are also shown.
Placement of an epoxy-bound sand core into the mold is demonstrated.
I would be happy to answer what questions viewers might have.
