Difference a cube, rotated at 45 degrees from a cylinder and translated 
so the edge touches the outside of the cylinder.

difference {
  cylinder {
   -0.5*y,0.5*y,1.0
   scale     <1.0,10.0,1.0>
   translate <0.0,5.0,0.0>
  }

  box {
   < -0.50, -0.50, -0.50 >, < 0.50, 0.50, 0.50 >
   scale     <3.0,3.0,3.0>
   rotate    <0.0,0.0,45.0>
   translate <1.112,0.0,0.0> /* translated so the edge touches the 
outside of the cylinder */
  }

}
