Making an Impression of the Back and Button Nub
In preparation for replacing the button on the back plate which will attach to the new neck Been needs to make an impression of the remaining button nub and the area surrounding it on the back plate.
On the left below you can see the green dental compound that will be used for the impression.
To protect the plate and make it easier to remove the dental compound Ben usually oils the surface and or place a piece of plastic wrap between the wood and the compound.
The dental compound has to be heated and worked in your hands until it is soft enough to be be pressed over the surface of the wood. Below the softened compound is shiny as it is pressed against the outside of the back plate with a block of scrap wood. You can clearly see the button nub against the green compound.
Below the impression is shown after it has hardened and been removed from the violin.
