Thanks.  The clip is a patch object.  Most everything else is just a lathe.
The grooves are created like this:

normal
{
  radial
  slope_map {
    [0.0 <0, 0.0>]
    [0.1 <0, 0.0>]
    [0.1 <0, 0.2>]
    [0.4 <0.2, 0.2>]
    [0.4 <0.2, 0.0>]
    [0.6 <0.2, 0.0>]
    [0.6 <0.2, -0.2>]
    [0.9 <0, -0.2>]
    [0.9 <0, 0.0>]
    [1.0 <0, 0.0>]
  }
  frequency 64
}
