I need a model of these sprockets, can't find any in 3d Contentcentral that

Peter,
A Sprocket model is not very difficult to make in SWX. Get
a Machinerys Handbook to get the dimensional information that you need
regarding the types and widths of chain, roller or ladder, the shape of
the tooth itself is all layed out and explained to you there. It is
just a simple sketch of one tooth, use the circular pattern and an axis
to obtain
the pitch that you need, extrude a hub and hole, (if required), and
revolve cut the tooth-face radii, and you should be Golden.
Good luck,
