The
crank pin design has also changed; there is still a pin (thicker now)
but it's pressed into the boss cast into the main gear. The main
gear has had its teeth cut from the solid rather than cast to shape as
in the earlier types; on closer inspection, the teeth have sharp
corners along their edges. And the gear now has a decorative bead cast
into the rim. Consequently, the gears mesh much more
smoothly. |
