ENGLISH TRANSLATION of the written notes in the video, in order of appearance :
00:04 - Fluting of soundholes wings
00:11 - The fluting of the wings, typical of Stradivari and Cremonese work in general, is done after closing the box so that the arching has assumed its stable and definitive shape.
This is necessary in order to properly evaluate the stiffness of the wings and of the entire area of the C bout channel that would otherwise be misleading in the free plate due to its excessive elasticity.
00:27 - From the aesthetic point of view, the cutting of the wing will have the purpose of lowering the lower part of the outer margin of the stem making it less slanted and with a more similar inclination as the inner margin in the side view of the box, with a more pleasant effect.
During the making of the free plate, the thickness must be kept higher than a few tenths of a millimeter across this entire area taking into account for final thinning.
