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)
