There are a lot of pictures here. My intention was to show the entire fit as well as a shot of the edge of the sound board. Point being that it is all fit well.
First to load are smaller files. Click on any photo and bring up a larger image
Every board done in the shop is to this standard.
It is the feeling of more experienced rebuilders that this tight fit is an important part of a very successful result.
The importance of this image is that it shows that the cut that is fit to the case is actually square and flush to the case. The entire edge contacts the rim, better fit, better sound.
