Queensland Metal - Introduction To Metal Spinning
During the metal spinning process a flat metal blank is held between a mandrel and clamping follower on a lathe that looks much like a heavy-duty wood turning lathe. The material is then worked by applying pressure by means of hand tool or rollers.
The hand tool is held under the operators arm and by using leverage off a peg in a T-rest, the material is worked in an arc motion from the bottom to the top. This motion is repeated until the blank has been drawn down to follow the same contour as the mandrel.
Roller spinning has the same basic concept as hand spinning but rather than a tool under the arm, a roller mounted on a hockey stick (scissor like tool) is used.
