00:00 - Back plate thicknesses part one - Gouge roughing - Creation of the channels

00:16 - Start by tracing the lines to delimit the gluing surface of the blocks and ribs, keeping abundant about 1 mm

01:49 - Using a thickness gauge adjusted to the height of the edge (4.5 mm) draw the limit of the fluting to be used as a reference during roughing, to avoid digging too much in this area

02:40 - Using a fairly curved and wide gouge (n°6 x 35 mm) start roughing, keeping within the fluting line

03:42 - Create a channel on the maximum width line of the lower bout

04:39 - Use a graduation punch to speed up the channel roughing operations, adjusting the measurement to 4 mm with the appropriate graduated wedge

07:27 - Repeat the operations at the upper bout, making a channel always on the maximum width line

08:41 - Locate the center of maximum thickness at the intersection point of the two diagonal lines that connect the tips of the ribs. Drill a hole to use as a reference, adjusting the depth to leave a thickness of 6 mm. Measure the distance from the lower edge, which should be around 190 to 195 mm (192 mm in this case)

09:30 - Rough out the central part, digging a channel in correspondence of the hole of maximum thickness

10:02 - To prevent the back from coming out of the cradle when roughing, apply two wooden swivel stops at both ends

10:32 - Adjust the graduation punch to 6 mm

12:08 - Adjust the graduation punch to 5 mm and dig the last two channels on the minimum widths at the corners. Be very careful to respect the fluting area , keeping within the reference line to avoid over-digging
