ENGLISH TRANSLATION of the written notes in the video, in order of appearance : 00:04 - Violin scroll part four - Marking of the back of scroll and pegbox 00:13 - On a marking gauge set a measure of half the width of the block to trace the center line of the scroll 00:23 - Verify that the measure is correct by matching the marks made by the two sides of the block, making the necessary adjustments for a perfect match 00:35 - Draw the center line using as backing only one side of the block for a better continuity of the line, avoiding that any differences between the two sides cause light doublings of the mark 00:51 - Draw markedly the plane of the neck and all the parts that will not be visible on the finished scroll 01:12 - Draw more gently the center line of the back as it will remain noticeable in the finished work, but making sure that it is still a clearly visible and continuous line 01:45 - Use the nut line (end of fingerboard) to locate the end of the back 01:58 - Use a reference drawing that shows the various measures and compass openings necessary for the full development of the back (cremonese method) 02:10 - Location of centers for circles 02:24 - Use a pencil compass to draw circles, setting the correct opening on the reference drawing 02:35 - Locate the center of the first circle starting from the end of back line 02:46 - Draw always full circles, because their balanced form will allow a better perception of the lines symmetry 02:59 - With the same compass opening used for the back, mark the maximum width of the pegbox at the height of the first peg 03:10 - This should never be less than 26 mm to provide sufficient space for the correct passage of the strings through the pegbox 03:21 - Put the square tangent to the volute to bring this point on the side of the back, finding the position of the circle at the end of the straight lines of the pegbox 04:08 - Using a compass with two steel points, transfer on the center line the centers of the circles of the first part of the development, which will end at the narrowest point of the volute 04:38 - Changing compass opening also transfer the centers of the circles of the second part of the development 05:14 - By setting the openings on the reference drawing draw all circles of the development 06:39 - With a flexible ruler draw the straight lines of the pegbox 07:07 - Transfer the width of the back on the front of the pegbox using a lower point, which will allow to draw more easily with the compass out of the throat 07:39 - Take the measure and transfer it on the front of pegbox 07:57 - Draw the straight lines of the box coming far forward as possible in the throat 08:34 - Also trace the widths at the nut and heel, connecting them with two straight lines to mark the gluing surface of the fingerboard 09:12 - Draw freehand the widening from the nut to the pegbox, trying not overlapping on the circles to avoid confuse them 09:33 - Do not draw any other line of connection between the circles to avoid to confuse them with overlapping of the lines, making them useless as a reference for the symmetry 09:53 - Index of videos : http://davidesora.altervista.org/vide... 09:59 - http://www.davidesora.it/ .
