The principle of the lathe goes back in time to ancient Egypt. This machine, which is used for making round objects, is necessary for making recorders and other woodwind instruments. This one has an electric motor and several turning speeds suitable for the different operations.
The lathe on the right, illustrated in Diderot & Dalembert's Encyclopédie (18th century) is operated by the spring pole fixed above the machine and linked to a treadle underneath via a cord wrapped around the axle. The machine turns at fairly low speed and in both directions. The operator would push the pedal down and work the piece of wood on the down stroke and then let the pole bring it back to the start position before being able to continue. | |
This lathe has a pedal and flywheel mechanism giving continuous rotation and variable speed. (from Bergeron Manuel du Tourneur) |
