Cam profiles (i.e. the shape of the outer edge of the cam against which the Follower engages) can be drawn as a Displacement Diagram using Drawing Instruments or CAD software.

Cams for models can be made simply by drilling an MDF or Ply Disc off-centre to make an Eccentric Cam or by mounting a disc at an angle to a dowel axle to make a Swashplate.

The use of Cams can most easily be explored using Contruction Kits such as those listed below.

The Pilot Bore Chain Sprockets are designed for British Standard Roller Chains which at ½" pitch are likely to be 8mm wide between the link plates. It is probable that these sprockets are too wide to accept modern thin Bicycle Chains - check with suppliers.
Bicycle Chains and sprockets are ½" pitch and only 3mm wide between link plates.
