Building Tage Frid's Workbench Deadman Using Only Hand Tools
"If you are working on long boards or panels, you can make a simple device to support the other end of the board. Cut a sturdy piece of wood, such as a 2x4, to the height of the bench top. Drill a series of holes at least 3/4 in. in diameter in a straight line down the length of the piece, about 1 in. apart. By clamping this piece into the right vise and placing a dowel in the hole just below the work, you can easily add support to a long piece." -Tage Frid
