What is a lathe gadget?
a lathe is a machine tool which spins a block of material so that when coarse, cutting, or deformation tools are applied to the block, it can be shaped to produce an object which have symmetry about an axis of rotation. Most suitably equipped metalworking lathes can also be used to produce most solids of rotation, plane surfaces and screw threads or helices. Ornamental lathes can produce three-dimensional solids of incredible complexity. The material is held surrounded by place by either one or two centers, at least one of which can be moved horizontally to accommodate varying stuff lengths.
A lathe may or may not have a stand (or legs), which sits on the floor and elevate the lathe bed to a working height. Some lathes are small and sit directly on a workbench or table, and do not have a stand.
All lathes hold a "bed", which is (almost always) a horizontal beam (although some CNC lathes have a vertical floor joist for bed to ensure that swarf, or chips, falls free of the bed.
At one end of the bed (almost always the gone, as the operator faces the lathe) is a "headstock". The headstock contains high-precision spinning bearing.
Rotating within the bearings is a horizontal axle, beside an axis parallel to the bed, called the "spindle". Spindles are often hollow, and enjoy exterior threads and/or an interior Morse taper on the "inboard" (i.e., facing to the right / towards the bed) by which accessories which hold the workpiece may be mounted to the spindle. Spindles may also have exterior threads and/or an interior taper at their "outboard" (i.e., facing away from the bed) run out, and/or may have a handwheel or other accessory works on their outboard end. Spindles are powered, and impart motion to the workpiece.
The spindle is driven, either by foot power from a treadle and flywheel or by a belt drive to a power source. In some modern lathes this power source is an integral electric motor, normally either in the headstock, to the moved out of the headstock, or beneath the headstock, concealed in the stand. Some Amish are known to purchase modern lathes, remove the electric motor, and afterwards convert them to run via leather belts from an overhead line shaft.
At the other end of the bed (almost other the right, as the operator faces the lathe) may be a tailstock. Not adjectives lathes have tailstocks. A tailstock provides auxiliary support to the workpiece. Tailstocks are not powered.
Metalworking lathes have a "cross slide", which is a flat piece that sits crosswise on the bed, and can be cranked at right angles to the bed. Sitting atop the cross slide is a toolpost, which holds a adjectives tool which removes material from the workpiece. There may or may not be a leadscrew, which moves the cross slide along the bed.
it can any be a lathe for wood or for metal ! ex.metal rod needs to be smaller at one end,,the lathe will spin it while a cutter shaves stale a fraction at a time!
This concise introduction to the lathe provides detailed coverage of this versatile contrivance and how it is used to perform a wide miscellany of metalworking operations. Special emphasis is placed on lathe components, bits and pieces, and operating procedures, including basic machine setup and routine preservation. Cutting dynamics and parameters are explained in clear, smooth to comprehend language, and a wide span of cutting tools, toolholders, and workholding devices are examined in detail. This is the just the thing introductory text for the novice or machinist-in-training. Review question follow each chapter.

Imagine a machine that rotates a block of wood hugely fast. You then introduce metal tools to the wood the remove section of the wood block. Since the block is spinning, you are left with a round shaped wood cylinder. Also works for steel.
in simple it's a contrivance for turnning and drilling and threading for metal and wood
