Rock Quarry tools of the 19th and early 20th century https://www.industrialheritagens.ca/apps/photos/ Rock Quarry tools of the 19th and early 20th century Prior to any rock drilling tools, to break the granite, holes were chiseled into the rock by hand. This was labour intensive, requiring two or three men working on every hole. One lucky man held the chisel/ drill bit in his hands and rotated it after every blow from a maul swung by one or two other workers. The hand-powered rock drill, complete with "star drill", shown here, must have been a welcome improvement for the sartorially elegant quarry man, https://www.industrialheritagens.ca/apps/photos/photo?photoID=203302790 203302790 Here's a photo of the traditional "plug & feathers" tools used to crack apart the granite. A set of these tools were placed into each hole along the cut line. The feathers were first inserted into the hole and the plug was driven into the hole between the feathers. As the plugs were tapped into the holes along the crack line the granite would split apart. https://www.industrialheritagens.ca/apps/photos/photo?photoID=203302791 203302791
