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.
How to Use a Drill Press Machine: A drilling machine comes in many shapes and sizes, from small hand-held power drills to bench mounted and finally floor-mounted models. They can perform operations other than drilling, such as countersinking, counterboring, reaming, and tapping large or small holes.
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.
