The lathe object is not suitable for that purpose.
The sor object allow more freedom in the shape. It can make torus-like 
shapes.
BOTH can't have wavy surfaces along a given circumference. They are 
shapes that are rotated smoothly around an axis.
So, while the sor can be used to make the body of your gear, it just 
can't model the teeth of the gear.

You are correct about the isosurface : IF you can come out with some 
function for your gear, it will make the ideal gear. It problem is 
devising that function.
