Tom,
I think that a 7" diameter is not going to be big enough for the eagle design Because of the width of the wings, the segment has to be pretty wide. The segment needs to be about 4" wide. A 7" diameter would have to have six segments of 4" and with only six segments, the segment would have to be very thick (probably 1.5") in order to turn the radius. I think you need to have a minimum of 8 segments and 10 is best. The one I made had 10 segments and I was able to start with 1-1/8" thick board because of having 10 segments. I don't think I would have been successful with less than 10 segments. With 10 segments, my Repeating Unit was close to 4" wide. Any less than this and you'll be able to make the segments, but I don't think you'll be able to turn it.
My suggestion for a 7" diameter bowl is to go with a nice SW design for a first attempt. I would make it 16 segments with a feature ring of 8 segments which would have a Repeating Unit in Lamination PRO of 3" (2.88" Segment Edge Length in Segment PRO).
