Curved wooden staves are fitted with metal hoops to create barrels, cast metal bodies and valves are assembled into fire hydrants, steel frames, foam and upholstery are combined into automotive seats, and glass envelopes and electron-gun components are manufactured into cathode ray tubes.

Iron is alloyed with chromium and other elements to produce corrosion-resistant stainless steel, molded shells and protective padding are assembled into football helmets, liquid resin is cast and decorated into figurines, and heat-resistant glass tubing is shaped into laboratory equipment.

Metal cylinders are formed, tested and filled to create fire extinguishers, rings of dough are fried and finished into doughnuts, pistons and hydraulic components are assembled into automotive shock absorbers, and wooden rims, stretched membranes and strings are combined into banjos.

Molded body sections are covered and mounted to make adjustable dress forms, metal is cast and precisely machined into boat propellers, insulating filling is enclosed in stitched fabric to produce duvets, and cast bodies, valves and handles are assembled into faucets.

Molten bronze is cast and tuned into bells, laminated hardwood is shaped and balanced into airplane propellers, powdered charcoal is compressed into uniform briquettes, and ceramic logs, gas burners and control systems are assembled into decorative fireplaces.

Steel blades and folding mechanisms are fitted into pocket knives, soft soapstone is cut and polished into decorative and functional objects, electrical windings and insulated cores are assembled into pole-mounted transformers, and wooden frames and woven webbing are fashioned into traditional snowshoes.

Sheet steel is rolled, welded and sealed into shipping drums, metal chambers are formed and tuned into police whistles, small-scale components are molded, painted and assembled into miniature train cars, and pressed sections of molten glass are fused into hollow building blocks.

Sweet batter is baked and rolled into ice cream cones, collapsible frames and furnished enclosures are installed on trailers for camping, waxes, dyes and solvents are blended into shoe polish, and steel is forged, machined and fitted with grips to make pliers.
