Casting a piston for a 1910 single cylinder engined Brush car, Part 1

Sand casting a piston for a 1910 Brush car. Part 1 casting the chills Here I cast some chills that will be used to improve the structure and decrease the porosity of some pistons to be cast later in Part 3 of this video series. The chills them selves will also be chill cast as they are quite thick and "chunky". The chill casting is a definite aid in making such castings much sounder and finer grained. Part 2 of this series - to be released soon - will cover the reinforced Silicate CO2 core that will form the inside of the piston mould.
