ENGLISH TRANSLATION OF THE WRITTEN NOTES IN THE VIDEO IN ORDER OF APPEARANCE

00:06 - Cutting of the channel

00:10 - Check that the edge has the desired thickness

00:15 - For me 4.1 mm in upper and lower bouts

00:18 - 4.5 mm at corners

00:21 - 4.3 mm in the C bout

00:42 - with special marking tool trace the channel width

00:50 - 11 mm in upper and lower bouts, 7 mm in the C bout

02:18 - I use a gouge n°6 x 13.7mm with a radius of 13 mm for upper and lower bouts

02:25 - Start by cutting a central channel more narrow and shallow

02:36 - Cut only the inner half of the channel reaching the marked line

02:51 - and cut only the outer half of the channel stopping at barely 1 mm from the edge

03:16 - Remove alternately on the two sides perfecting lines

03:31 - and reach the final depth removing even at the center of the channel

03:45 - With a thickness gauge check from time to time the thickness reached, which should be 3.1/3.2 mm in lower and upper bouts, 3.4/3.5 mm in the C bout

03:57 - Refine the channel by removing all the bumps, reaching a uniform thickness

04:04 - Feel by touch the presence of humps and irregularities, eliminating them where needed

04:09 - Proceed with great caution in sections with problematic grain, taking away a little at a time to avoid tear-out

04:33 - Bring the channel directly into the C bout, without entering in the corners, obtaining a profile in the shape of "8", passing inside the line of the blocks

06:58 - Connect the two channels in the upper part at the button, taking care to obtain continuous lines and not to dig excessively this area particularly stressed by the pull of the neck

07:35 - For the C bout I use a gouge more curved and narrow, n°7 x 11mm with a radius of 7mm

08:34 - As the last thing cut the channel in the corners, taking care that it ends to zero depth at the exit from the corner, linking it well without digging it too deep

08:40 - For this task I use a small and flatter gouge : n°6 x 10.5mm with a radius of 10mm

08:57 - Connect well with the rest of the channel finishing carefully the edge line

09:30 - At this point, we will proceed with the marking and cutting of the purfling channel, as described in the video "Filettatura Parte Prima" (Purfling Part One)
