Making Stringers & Knees from XPS foam [part 1] - Dream Boat Build

This video shows me making Stringers and knees from XPS (Extruded Polystyrene) for my boat. This is the first segment of the build, and it includes how I found dead center, made a line drawing fixture thing to mark my stringer placement, and epoxying and cutting XPS foam board for about a third of the stringers / knees.
Im still learning this editing software. Please forgive any screwups...
