Here is a unique original-design blueprint-style poster featuring the "machines that made the machines" - four mighty locomotive shop lathes used for machining different parts of steam locomotives in the early 1900's. Four different styles of lathe are presented in blueprint-style line diagrams, with parts lists: a general "Engine Lathe", a "Double Axle Lathe", a "Heavy Duty 90-inch Driving Wheel Lathe" and a "Hexagonal Turret Lathe." These tools, operated by highly skilled machinists, built the machines that built America, and now you can display them as part of your home, man cave or train room decor. This poster makes a great gift for any railfan, machinist, engineer or other person who loves tools and mechanical marvels. • Paper thickness: 10.3 mil • Paper weight: 5.57 oz/y² (189 g/m²) • Giclée printing quality • Opacity: 94%
