S27E12: Race Car Oil Tanks, Plaster Mouldings, Lemongrass Oil, Fly Tying Vises

Lightweight metal is formed, welded and pressure-tested into oil tanks designed for racing vehicles. Decorative profiles are reproduced as plaster mouldings; harvested lemongrass is steam-distilled to extract its aromatic oil; and machined jaws, pivots and adjustable bases are assembled into vises that hold fishing hooks during fly tying.
