'End of Fingerboard' neck tuning....
(Modified 3/2018)
...This will be one of the last tuning steps to complete an acoustically tuned violin. Complete the scroll and peg box areas with tuning pegs installed. Complete the shaping of the underside of the neck and fingerboard tuning. Then : ....
...When we tap the neck wood sideways just under the intersection of the fingerboard and nut, we want this tap tone to be the same as the back plate {198 HZ/ G below middle C on the piano).
...The side tap of the neck wood just under the fingerboard should already be at 198 HZ Tap Tone; this is the last step; and is adjusted separately by the shape of the back of the peg box... You will need to adjust separately so that this side tap is the same on both sides of the neck and both equal to 198 HZ.
...This will also help with the beauty and brilliance of the tones played.
Ideal Tap Tone...
........198 HZ
..This is the side tap frequency we want to adjust to 198 HZ
..This back surface of the peg box controls the side tap we are interested in adjusting.
..If the side tap shown above it too high (above 198 HZ), then a even layer of wood will need to be glued on to make this end surface thicker.
..If too low (below 198 HZ), then wood is removed evenly from top to bottom on the side that is too low. If both sides are evenly low, then remove wood evenly from the back of peg box until the side tap is adjusted.
..I normally use a sharp flat blade chisel to carve away the excess wood.
..Only small amounts make a change.
..Tap along this surface from bottom to top in area of adjustment and remove first the any areas with higher tap tone than others.
