Metal Spinning Trycksvarvning

An animation showing metal spinning (by hand). Called trycksvarvning or metalltryckning in Swedish, metall drücken in German. It is simplified,
in reality you need many more strokes to produce one item.

This craft is an old and spectacular one. The basic idea rely on
the transformation of a round sheet (a blank), into a symmetric object. Metal spinning performs just that, in contrast to more wellknown works by the lathe.

The lathe is more of a sturdy wooden type. At the lathes shaft will a form
(mandrel) be located. A mandrel can in its simplest form just follow the inner contour of the desired shape, but can also only support a smaller part, or be dividable. To fix the blank against the mandrel, will a support (follower) be used. This and the blank will then be hold in place by the force from the tailstock.

As support for the tool will a steelpin in the toolrest be used. This has a row of holes, so the pin can be moved on, when work proceed. With rhytmic, smooth strokes, will then a circular blank transform into a bowl, chalice, et cetera. You may though had to spin in several steps, or use more then one part, to perform a complete item.
