advanced violin restoration techniques - International Specialised ...

Attachments
thin as possible flatten the edges of the corresponding paring using a
scraper check that they fit together well fix the paring with tape
− prepare a piece of rubber and a piece of hard wood to use to press the paring on
the table
− glue with hide glue
− let it dry overnight
− do one by one in this way
− when all the holes are filled, scrape the uneven edges and press some thin lime
wood veneer on the patch area
− when dried scrape it again and. fit the patch
Through wood method with new wood:
make a plaster cast
make a groove where the worm holes are and flatten the edges of the worm
holes, as thin as possible so that you get a canyon-like inside to the violin make a
plaster cast of this inner side landscape copy it with a milling machine
− soak it with glue
- copy it again glue with hide glue

Why do you think it’s necessary to change the angle? The violin needs specific
pressure on the bridge on the table. 3 points determine the pressure:
1. What is the overstand at the neck foot?
2. What is the projection of the fingerboard at the stop?
3. What is the height of the saddle?
To get the best possible acoustic resul4 you have to think about these 3 points
in relation to the arching and the thickness of the front and back. The overstand has to
be between 6.5 - 8mm and the projection is almost always 27.5mm at the stop.
The saddle should be around ehlnn.
Why does the angle gel lower?
- After a couple of months in use the angle sometimes changes in recently
restored or newly built instruments. The arching sinks and / or the back gets
rounder, the fingerboard drops and the strings rise the musician complains about
greater playing difficulties - decreased attack, too much pressure on the fingers.
the cause: if the violinist plays a note, the angle of the string at the bridge
has increased so the pressure is too high. It is preferable to lake some
pressure off the bridge
If you look at the overstand, there are 2 possibilities: reset the neck change the angle
If the overstand is OK, then choose option 2. It is easier, cheaper and also works well.
