I tried 'Flow' but...

 From:  Mike K4ICY (MAJIKMIKE)

For a revolved surface like that, you should consider the method I use for Flow.
Where you align your objects on a flat revolved reference surface that mimics the same point arrangement as the target surface.

See an example here: http://moi3d.com/forum/index.php?webtag=MOI&msg=4673.1

As for the wavy result... I bet you used "Projection" to place those clock objects?

If you see here: http://moi3d.com/forum/index.php?webtag=MOI&msg=4668.1

Michael notes how the Projection mode takes into account some type of ray-tracing calculation that gets very funny after the surface normal is too high in degree away from the target object.

With a standard Flow with every object simply being wrapped around the target surface, the result is more point-to-point.

Hope this helps.
