Combination Squares, Farmed Shrimp, Ball Valves, String Trimmers

How It's Made – Season 27

Steel rulers are marked and fitted with adjustable heads to produce combination squares used for measuring and layout work. Shrimp are bred and raised in managed ponds; machined valve bodies receive drilled spherical closures that regulate fluid flow; and engines, shafts, guards and rotating cutting heads are assembled into string trimmers.
