The bottom rear turtle deck will be sheeted with 1/16" balsa.

The skins can be laid out and rough cut to shape by trial fitting (dry). I simply use masking tape to hold the sheets together. These sheets can be glued together (ambroid is a favorite) to create the skin as well. This core is about 41" long and if you do not have any 48" long sheets, you will have to add another section of balsa to reach the full length. I have not found this to be any problem and in fact, by picking a very plyable scrap piece for the tail end of the core, I can get the sheeting to wrap rather well around the tight radius at this end.
