S32:E2 Custom Shoe Trees, Clay Targets, Squeeze Chutes, Composite Boat Propellers
First Aired: February 17, 2019
Runtime: 21 min
Wooden blocks are copied from precisely fitted models, hollowed, divided and hinged to create custom shoe trees. The episode also follows petroleum pitch and mineral powder as they are moulded into breakable clay targets, steel components as they become livestock squeeze chutes, and fibre-reinforced composite as it is injection-moulded into boat-propeller blades.
