OK...
So I bought two 1/2 inch thick ply sections. One of oak and one of birch. I am going to use Mat Amp's guide on an aspis by extending the center point of each half circle about 6 inches. Easy. I take a sring and pencil and carefully draw a half circle section from each point. This afternoon I drew a cross section and realized the thing would be 40 x 34 inches. I note Comerus's two pics. One is clearly the diameter of an aspis. The other is slightly less that the opposing warrior's artist. (I measured with calipers.) I am not sure the artist had a concept of depth or not. The difference is not really apparent until you measure. I know how to draw circles with string but not an ellipse.
So. Do I:
1. Make the thing 34 x 40?
2. Attempt to narrow it to about 30-31 x 40, using a clever method that you will tell me how to do.
3. Give up and make an aspis, although I really want a Boeotian, knowing I will make uneven ellipses. Note: I also used my wife's checkbook to buy the plywood with and a new laser jigsaw because she was in Virginia visiting her family. Botching the job on top of writing the check would be not a good idea.
