Pin Jaws
Pin jaws are typically used to expand into a deep
recess cut into a bowl-shaped workpiece for initial
roughing of the outside and tenon (or foot).
When used to grip the inside of a recess, the
advantage to pin jaws over step or round jaws is
that they offer a lot of surface area for gripping.
They also have ridges on the outside for greater
gripping power. The disadvantage is that the
recess must be fairly deep. However, this is usu-
ally cut into the waste portion of the workpiece
and removed later.
The smooth center surface of the pin jaws can
also grip externally around a small tenon on
objects such as Christmas ornaments, wooden
tops, lace bobbins, or other delicate work without
marring the workpiece.
