This nice Italian violin from the 1940’s hit the floor from shoulder height….causing the neck to erupt at the button are and the center seam of the back to open up. (There were also cracks on the top and ribs which I restored but won’t be part of this post)
The button is a very delicate spot….at once, stressed by the string tension pull on the neck and compromised by the purfling channel which cuts through almost half the thickness at that area. It looked like this violin hah been repaired here in the past … but not patched to span the weak area of the purfling channel cut. So its no wonder that it erupted….
The first step is to carefully remove the back and free the damaged button from the top block.
Once the button is carefully re-assembled and precisely glued back t the back a cast is made of the upper back to aid in the delicate cutting of a channel to fit the patch and eventually glue it in without distorting things.
Once the maple patch is fit and glued in the channel ( which has been worked down gently to 2 mm thick) it is planed flush with the platform that will be glued to the top block.
Once the back is re-glued to the ribs and the neck reset …. the only evidence of the accident is the the sliver of the patch existing as a layer between the button and the neck stock…. until with patient varnish restoration everything disappears…the only slight reservation in this instance are the lines on each side of the button repair that are from the previous repair that can’t be removed …. also on the side photo of the upper rib ….there is a 2″ crack in the mid part between neck and the rib miter …coming up diagonally from the back ….see if you can see it
Mr Moennig was quite a master of varnish touch up and restoration …and working with him has had a life long effect. You learned by doing the wood work and handing it to him to restore the varnish ( all the while carefully examining my work!). Eventually you were able to do the whole repair and then hand to him to cast his eye over it….an eye that was very at home with looking at the finest instruments and the finest restoration….just the eye you want looking at your work
