Just going to work the outer wedges for awhile to prep the main funnel shape. The two verticle lines in the center are the first stations, the diagonal is station 2 at the top and station 3 at the bottom in this picture. The lines help define the area to be worked, helps keep you focused on a smaller section of the part.
Worked the wheel in both directions staying out of the middle for now. Once the metal raised up some worked raising the middle up some more, now it looks like this. With light finger pressure it touches the four stations now.
