This lovely old violin came my way recently in quite good condition and looks to be well made. However the neck is what let it down and it turned into quite a rabbit hole.
The button had at one stage been broken on the violin and been repaired with an internal button graft , complete with wooden pins. Higher up on the neck root signs of fracture, were plan to see. A neck graft was required…
On disassembly the reason for the fracture was plain, the screw holding the neck to the body had rusted into the timbers. This method of neck attachment, as a butt joint was common on older violins, especially baroque era instruments. Today it serves less well as there is a lot of strain placed on the button and end grain gluing of the neck root to the ribs is not considered sufficiently strong for modern higher tension strings. Originally the neck and top block would often be nailed together for strength, though on this instrument was likely replaced by a screw.
The solution for this instrument was to graft on a new neck root, ensuring plenty of parallel grained timber for strength as end grain gluing is not that strong. Also a modern neck joint was carved into the neck block to increase gluable area at the bottom of the neck root and mechanical strength of the joint as well.
Once this was undertake, neck angles set and the button graft attended to, it was time to finish the neck with sufficient traditional pigments and a bit of “splodge” to blend in better.
I’m looking forward to playing this instrument…but first the peg box needs some attention as well…so I need to be patient
