Almost in plant equipment was built on sight and sometimes no drawings were used. The ability of American fabricators in the late 1700 and the 1800 amazes me. A case in point is Otto Mears a German immigrant that built most of the three foot gauge railroads in the Colorado Rockies. He had a third grade education

A clothing iron‚ also called a flatiron or simply an iron‚ is a small appliance: a handheld piece of equipment with a flat‚ roughly triangular surface that‚ when heated‚ is used to press clothes to remove creases. It is named for the metal of which the device is commonly made‚ and the use of it is generally called ironing. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are
