OK, here’s a little explanation… What you see is just the lower part of the engineering hull from the first horizontal frame down. The templates on the floor are the two main horiz frames
and the third one is the partial frame, that connects directly to the lower primary hull frame.
The first set of frames will be laser cut styrene, then those same patterns will be used to precision laser cut aluminum. The styrene will be epoxied to and screwed to the aluminum frames, the aluminum frames will have steel supports screwed to the aluminum. The shellwill be layers of petg and styrene.
Trying to make this as light as possible
