Henk,

Except where the neck meets the body of the violin. Think of all the bending stress created by the tightness of the strings.

Henk,

I think hide glue actually has quite a bit of shear strength to it. Mel mentioned earlier that it could and sometimes did deteriorate over time, but a lot of that has to do with the condition of the finish. Heck, look at old musical instruments like Stradivarius violins. They were made using hide glue. And I would bet that there are places on a violin that see more constant stress than our old fishin' poles. The finishes on most old Strad's are kept in pretty good shape, considering the age, and I would think that has a lot to do with how well the violins hold together.

Yep, but stresses on musical instruments are different in direction. Maybe I'm using the wrong terms here, but a violin's glue joints are under a stress perpendicular to the glue joint's plane, whereas a bamboo rod's glue joints are under a stress tangential to their plane.
