Default RE: Large composite shell using molded balsa

The turtle deck and fin assembly will become integral stressed portions of the fuse, so composite shells are used. The method used is a bit different than discussed in the previous posts.

- Frame structure is built on top of fuse, but not yet attached.
- Balsa skins are glued up.
- Balsa skins are water saturated and then pinned to the frame structure for drying. Skins assume compound curvature of the frame.
- Inside surfaces of skins are glassed.
- Frame structure is glued to fuse, skins are glued to frame structure.
- Outside surface will be glassed.

A bit tedious, but the results are good. This method also works well on fuselage structures if the compound curvature is not too severe.
