Braces and Drills
Braces are tools to hold drill bits. Drills used gears instead of a hand crank and were typically used for more specialized purposes.
Levels and Inclinometers
Levels used during the Civil War were very similar to the levels of today. Their function is just as their name implies--to ensure that an object is level. Inclinometers measured the angles of a slope and looked like a mantel clock with a huge base.
Planes
Planes were used to smooth floors and door panels, eliminating the risk of splinters. Planes were made of wood. During the Civil War era, the wood was of a high quality. Rosewood, mahogany and ivory were popular choices. In the mid to late 1860s cast iron-bodied hand planes began to be produced.
Rules
Rules were the ancestor of our rulers. They measured objects but were generally flat. In the 1860s folding rules were produced.
Miscellaneous Tools
Saws of the Civil War period were much like the saws used today. There were many designs for saws. Each type was designed for a specific use or to be used with specific materials, Carpenters also used chisels, axes and knives.
