S31E3: Spinning Reels, Plasma Protein Therapies, 3D Cups, Stainless Steel Beer Kegs

Precision gears, spools and drag mechanisms are assembled into fishing reels; donated plasma is separated and purified to recover proteins used in medical therapies; moulded cups receive graphics designed to create a three-dimensional effect; and formed stainless-steel sections are welded and pressure-tested as beer kegs.
