S32E8: Belts, 3D Metal Printers, Detectable Warning Panels, Model Stirling Engines

Carefully inspected cowhide is cut into strips, bevelled, dyed, decorated and fitted with buckles to produce leather belts. Precision components are assembled into machines that deposit and laser-fuse metal powder, glass-reinforced resin is compression-moulded into tactile warning panels, and finely machined pistons, cylinders, crankshafts and flywheels are combined in working model Stirling engines.
