Violino - Filettatura Parte Quinta : incollaggio dei filetti

Sistema di incollaggio dei filetti del fondo di violino dopo aver fatto le punte a secco. Per la tavola il sistema è uguale, solo che le parti superiore e inferiore non sono in pezzo unico ma in due parti separate giuntate non in corrispondenza della mezzeria ma sfasate di circa un centimetro per rinforzare la giunta della tavola durante le successive lavorazioni.
Le giunte dei filetti verranno poi a trovarsi in corrispondenza dell'incastro del manico e del reggicordiera e non è quindi necessario farle in modo perfetto.
E' possibile fare lo stesso anche sul fondo tenendo le giunte più sfasate rispetto alla mezzeria e facendole in modo perfetto così che non si notino, tagliando verticalmente i filetti a 45° nel punto d'incontro (sistema cremonese classico).
System for gluing the purflings of the violin back after making the dry fit of mitres. For the top plate, the system is the same, only the upper and lower parts are not in one piece but in two separate parts jointed offset by about 10 mm from the centerline to reinforce the joint of the plate during subsequent processing.
The joints of the purflings will then be in correspondence with the neck joint and the lower nut and therefore it is not necessary to make them perfectly.
It is also possible to do the same on the back plate by keeping the joints farther from the center line and making them perfectly so that they are not noticed, vertically cutting the purflings at 45° at the meeting point (classic Cremonese system).
ENGLISH TRANSLATION of the written notes in the video, in order of appearance :

00:05 - Purfling part five

00:09 - Gluing the purfling

00:18 - Start by locking the upper mitre with a drop of glue

00:26 - Gently pull out and lift the C

00:37 - Apply glue in the channel using a pipette dropper

00:47 - Do not let the glue enter in the tip of the channel but stop at about 4 mm from there

00:56 - Insert the lower tip before the glue reach and fill the mitre

01:02 - ...and insert the rest of the C by pressing with fingers

01:09 - Press well using a little hammer with rounded head

01:22 - Hammering gently to seat well the purfling and glue

01:41 - Brush up a bit of glue on the purfling to seal it well

02:01 - Lock the upper tip of the second C

02:12 - Pull out and lift...

02:22 - Apply the glue...

02:37 - Stop before the lower mitre...

02:43 - Insert the tip...

02:48 - and the rest of the C...

03:00 - Press down...

03:20 - Hammer to seat...

03:36 - Brush up a bit of glue

03:44 - Repeat the procedure for the upper bout

03:49 - Lift the purfling without removing the tips (already glued)

04:44 - Hammer from the center to the corners, so to let the glue run into the mitres

05:10 - Press well...

05:30 - Brush up the glue...

05:44 - Proceed also with the lower bout completing the gluing of the purfling

07:27 - Clamp the plate on a flat glass during glue drying to prevent any deformations
