Because of the First World War, Wegener's book went unnoticed outside Germany. In 1922, however, a third (revised) edition was translated into English, French, Russian, Spanish, and Swedish, pushing Wegener's theory of continental drift to the forefront of debate in the Earth sciences.
A drilling machine, called a drill press, is used to cut holes into or through metal, wood, or other materials (Figure 4-1). Drilling machines use a drilling tool that has cutting edges at its point.
Drill press table benefits. Drill presses are designed for working with metal, not wood. Thatâs why, 10 years ago, I screwed an old scrap of 3/4-in. treated plywood to the metal table so I could screw down or clamp stops and fences.ut the clearance hole on the fence with a 2-1/2-in. hole saw on the drill press. Screw the fence together before applying the laminate, then rout that as you did with the tabletop. Lag screws (1-1/2 x 5/16 in.) and washers work great for securing your new top to the existing drill press table.
