The drawing of the shape of the table (ellipse) and the inlay is done very fast - the ornament as well. I just used an existing jpeg and converted it into vectors.
To cut the ellipse of the table (30 mm) I decided to use the SO just for cutting the shape with a depth of 6 mm. For the final cut I used a jig saw and a big router with a router bit with ball bearing guide.
A litte tricky was the 3 mm walnut-inlay: the radius was too narrow to bend it into the groove. So, I had to steam it with hot water carefully...what worked very well.
