Casting a piston for a 1910 Brush car. Part 3b Casting, breakout, and discussion

Sand casting an aluminium piston for a 1910 Brush car. Part. 3b Pouring the sand mould. This final part of the video series also includes a "post casting" discussion centred on the gating system used. In addition it addresses the oft asked question of "why not just CNC machine the piston from billet". I recommend watching parts 1, 2, and 3a first.
