Aircraft-grade aluminum is forged and heat-treated into carabiners and other climbing equipment; wet leather is moulded over a metal bicycle-saddle frame; and lightweight chassis, powerful drivetrains and carefully finished body panels come together in luxury sports cars. 07 Replica Foods, Traffic Cone Dispensers, Rocking Horses, London Taxis Episode 77th May 2010 Real dishes are used to make silicone moulds from which durable plastic replica foods are cast, trimmed and hand-painted. Welded frames, motors and robotic arms form machines that deploy and retrieve traffic cones; hardwood pieces are carved and joined into traditional rocking horses; and purpose-built bodies, drivetrains and passenger compartments are assembled into London taxis. 08 Miniature Furniture, Garden Steam Locomotives, Hovercraft, Folding Bicycles Episode 814th May 2010 Craftspeople reproduce the joinery, upholstery and finishes of full-sized furniture in miniature. Precision-machined boilers, cylinders and running gear become working garden steam locomotives; lightweight hulls, flexible skirts and propulsion fans are assembled into hovercraft; and hinged frames with secure locking mechanisms allow bicycles to fold into compact packages. 09 Crosscut Saws, Haggis, Collectible Firearms Episode 921st May 2010 Steel blades are cut, toothed, hardened and sharpened to produce crosscut saws capable of slicing cleanly across wood grain. Organ meats, oatmeal, onions and seasonings are prepared and packed into traditional haggis, while machined metal components and carefully fitted wooden stocks are finished and assembled into collectible firearms. 10 Alligator Bags, Lockers, Bench Planes, Deployable Flight Recorders Episode 1028th May 2010 Selected alligator hides are cut, reinforced, stitched and finished into luxury handbags. Sheet metal is punched, folded and joined to make storage lockers; cast bodies, sharpened blades and shaped handles become woodworking bench planes; and protected recording units are enclosed in deployable housings designed to preserve aircraft data after an accident. 11 Grapples, Flavorings, Dog Sleds, Athletic Shoes Episode 114th June 2010 Heavy steel parts are cut, welded and fitted with hydraulic mechanisms to create industrial grapples. Natural and synthetic ingredients are extracted, measured and blended into concentrated food flavourings; shaped wooden components are joined and reinforced to build dog sleds; and layers of fabric, foam, rubber and supportive materials are cut, stitched and bonded into athletic shoes. 12 Retractable Cords, Wood Frame Sports Cars, Sushi Episode 1211th June 2010 Insulated electrical conductors are wound around forms and heat-treated so they repeatedly return to their compact coiled shape. Traditional timber frameworks are shaped and joined before receiving metal body panels and mechanical components in wood frame sports cars, while seasoned rice, seafood, vegetables and seaweed are carefully prepared and assembled into sushi. 13 Leather Wallets, French Horns, Soy Sauce, Children's Ride-On Cars Episode 1318th June 2010 Leather is cut, thinned, lined and stitched into wallets with precisely fitted pockets and compartments.
