The
handle of the North Star extruder is longer than usual while the
barrel is smaller than usual. This gives plenty of leverage without
ratcheting. Consequently, there are no dangerous shackles, fewer
pinch points, no clumsy multi-jointed handle to come loose, and no post or
ratchet parts to wear out. The handle is anchored at one fixed
pivot point, completely eliminating the danger of a heavy steel bar
slipping or suddenly offering no resistance. Clay is loaded with the
handle in the down position, again eliminating danger from a heavy,
hard-to-control handle. These
machines hold about eight pounds of clay, which will give a longer
extrusion than most people can handle at one time. This model should not
be used with porcelains, pure white stonewares, or in situations where
clay remains in it for a long time.
