A correctly dimensioned and properly positioned neck is crucial for the functionality of an instrument. A skilled violin maker / repairer can also use the neck to make significant tonal adjustments. There are many variables in neck dimensions and most makers have their own views on what is optimal. If the neck has been broken, or excessively worn, it may have to be replaced.  in this example the old neck had an accumulation of minor problems and the quality of the instrument justified the expense of fitting a new neck.

The procedure outlined here is the same as that to which most classic period instruments were subjected in the 19th century when the broad, low angled baroque necks were replaced with modern necks.  The scroll, which must be preserved as part of the original instrument, is grafted onto a block of wood which will be used to form the new neck.
