25 - Special Table Saw Issue, страница 32
Scenes from the Shop A Built by the J.M. Marston & Company, this 1873 forerunner of today's table saw is used in a turn of the century shop at Des Moines' Living History Farms. After tilting the table to adjust blade height, the saw blade is rotated by stepping on afoot pedal, or having a helper use an optional hand crank. A A simple set of gears transfer the momentum of the spinning flywheel directly to the arbor the saiv blade is mounted on. A By turning this small hand-wheel under the front edge of the table, the top is raised and lowered instead of the blade. |
