I did mine by figuring the cut angles and rotating + subtracting bodies from a cylinder. You have 3 different cuts. I would approach it like a 6 sided object. Once you have the correct angle, simply rotate the the flat body 60 degrees and subtract. (see the top 6 triangles and the bottom 6 below them?) That will achieve the crown cuts. Then you have to figure the angle for the 12 upper girdle cuts.
In mine (see below) I drew a side profile on a construction plane, rotated it to create the 8 main features. I created a construction plane at the girdle and drew a top profile. That helped me figure the cut angle with the visual profile and top drawing. Note: you can create a construction plane between 3 points (See the triangles? 
from those I created a construction plane drew and extruded a body to cut from the cylinder, rotated 7 times and cut. I did this for each of the main cuts). Now some of the complex girdle cuts I couldn’t find the correct angles documented so I guessed.
