I cut the side panels for the shell last night. Started by tracing the top profile onto a side piece. Then offset the line down 1" so that I could lay the top panel over top of the side panels.
Copied to other side:
And then glued a second strip of foam along the top of each side panel so that I could sand far enough into them to get the curve I want. The pic isn't so good, but you can see the glue coming out along the curved top of each panel:
I'm going to be out of town all weekend, so next update, attaching side panels and top, will be next Monday. Happy Friday!
