Copy of the "Kochanski" Guarnieri Del Gesu.
Making a copy of a specific instrument is an exercise in observation, trying to discern what goals the maker had in mind and what working methods he may have used to get there. Looking at Del Gesu's work, you get a strong sense of efficiency and economy of effort. Tricks like extending the corners well beyond the rib ends allowed him to avoid the troublesome tight bends in C-bout ribs. Looking at the variety of line in his instruments, I suspect that he made minimum use of templates, but rather worked from a few layout points and then relied on his eye and the shapes that his tools naturally made to guide him.
