ENGLISH TRANSLATION of the written notes in the video, in order of appearance :
00:05 - Top plate thicknesses part one - Gouge roughing
00:18 - Start by tracing the lines to delimit the gluing surface of the blocks and ribs, keeping abundant about 1 mm
01:36 - Using an adjustable thickness gauge set to edge measurement (4.5 mm) draw the limit of the fluting to be used as a reference during roughing. Trace also the F- holes so you can visualize their position, to avoid digging too much in these areas.
02:54 - Using a fairly curved and wide gouge (No.6 x 35 mm) begin to rough out the lower bout, creating a channel on the maximum width line. Set the graduation punch to a measure of 4 mm, so that once all the holes of the punch are removed, an effective thickness of about 3.5 mm remains
05:40 - Use a flat and wide gouge (No.3 x 35 mm) to connect the lower area from the channel up to the gluing surface of the block, bringing it to the same thickness of the channel (3.5 mm)
06:32 - In the same way, also roughen the upper bout, bringing it to a thickness of about 3.5 mm
07:42 - Rough out the central part in the longitudinal direction, paying attention to the direction of the fiber to avoid tearing the wood, creating two channels on both sides of the center joint using the curved gouge. Set the graduation punch to 4.5 mm so that once all the holes of the punch have been removed, an effective thickness of about 4 mm remains
09:42 - Connect the lateral parts using the flattest gouge, paying attention to respect the convexity of these areas to avoid digging too much, especially in the lower eye area of the F-holes
11:14 - Check the frequency of the highest note emitted from the top plate (mode 5, percussion and listening at the center) that at this stage of the working should still be higher than Sol (G 392 Hz)
