TITLE: Wood Lathe OBJECTIVES: 1. To be able to operate a wood lather 2. To familiarize the students with the different parts of wood lather. 2. To be able to produce a required rounded specimen of given dimension METHODS/DISCUSSION/ANALYSIS: Lathe is a very ancient tool and its first use dates back to 1300 BC in Egypt. Lathe was also known and used in Assyria and Greece. Ancient Romans came to know about this machine and they further developed this machine. During the medieval period, the use of this machine had spread to most parts of Europe and it was during the Industrial revolution when this machine gained popularity with its use in all the industries. As humans began developing tools and technology, honing new skills, and began more efficient ways of production, different power sources started to become standard. Motors now required electricity, meaning the conventional way of operating machine tools by human touch was being phased out as more and more machinists were “turning” to automation. But before automation and metalworking became regular practices in the machining world, there was woodturning and thus, wood lathes. Woodworking lathes are the oldest variety. All other varieties are descended from these simple  lathes. An adjustable horizontal metal rail – the tool rest – between the material and the operator  accommodates the positioning of shaping tools, which are usually hand-held. After shaping, it is  common practice to press and slide sandpaper against the still-spinning object to smooth the surface made with the metal shaping tools. The tool rest is usually removed during sanding, as it may be  unsafe to have the operators hands between it and the spinning wood. Many woodworking lathes can also be used for making bowls and plates. The bowl or plate needs  only to be held at the bottom by one side of the lathe. It is usually attached to a metal face plate  attached to the spindle. With many lathes, this operation happens on the left side of the headstock,  where are no rails and therefore more clearance. In this configuration, the piece can be shaped  inside and out. A specific curved tool rest may be used to support tools while shaping the inside.  Further detail can be found on the  woodturning  page. Most woodworking lathes are designed to be operated at a speed of between 200 and 1,400  revolutions per minute, with slightly over 1,000 rpm considered optimal for most such work, and with  larger workpieces requiring lower speeds.
