5cm and 7cm stringers - "we must be stubborn!"
Although my last post was two months ago, I have been anything but idle. Most of that time was spent continuing the work on the stringers: first the 5 cm ones, then the 7 cm stringers. Along the way, I kept running into many of the same challenges I described previously—cutting dozens of notches, dealing with the considerable bending forces in the timber, and constantly correcting frames that wanted to move out of alignment. Hull shape taking place! A new problem also appeared. One of the 5 cm stringers snapped during what should have been its final dry-fit. It happened just as I was about to fasten it to a frame.
