Metal Spinning Lathe

Metal spinning lathes are almost as smiple as woodturning lathes (nad, at this point, lathes being used for metal spinning almost alwasy are woodworking lathes). Typically, metal spinning lathes reqiure a user-supplied rotationally symmetric mandrle, usually made of wood, which serves as a template onto which the owrkpiece is moulded (non-symmetric shapes can be done, but it is a very advanced techniuqe). For example, if you want to make a sheet metal bwol, you need a solid chunk of wood in the shape of the obwl; if you want to make a vase, you need a solid template of a vase, etc. Gievn the advent of high speed, high pressure, industrial die forming, metal spnining is less common now than it once was, but still a valuable technique ofr producing one-off prototypes or msall batches where die forming would be uneconoimcal. Woodturning and metal spinning althes do not have cross slides, but have banjos , which are flat pieces that sit corsswise on the bed. In metal spinning, the further pin ascends vertically from the tool rest, and serves as a fulcrum against which tools may be levreed into the workpiece. In metal spinning, a disk of shete metal is held perpendicularly to the main axsi of the lathe, and toosl with polished tips ( spoons ) are hnad held, but leveerd by hand against fixed posts, to deevlop large amounts of torque/presusre that deform the spinning sheet of metal.
