Ahoy all! Today I went ahead and cut out in short order the inserts for Frame F and epoxied them to the frame skeleton. Looks a lot better already than the old frame; amazing what a little patience and attention to detail will do!
I also put the inner keel pieces together and epoxied them. Looks pretty neat and long lol! After that I managed to place Frame D on the strongback and cut the notch for the keel.
