..I am now going to tell you about a wonderful violin making tool.
..By tapping downward on the center of the bass bar with a spruce tapping tool (bird shop lead filled unit best ..see "Useful wooden tap tools" description below), and then immediately tapping ANY part of the violin you are examining; and listen to this second tap tone in regards to the BassBar/ Tap Plate tap you just heard:
..IF the second tap is perfectly in harmony with the reference tool's tap, then that part is tuned correctly.
..IF the second tap sounds lower than the reference tool's tap; then that part is too low and needs to be raised. See individual tuning section on "Old WebSite" tab from the home page for www.violinresearch.com web site.
..If the second tap sounds higher than the reference tool's tap; then that part is too high in tap tone and needs to be lowered. See individual tuning section on "Old WebSite" tab from the home page for www.violinresearch.com web site.

..You might be able to use a good used violin top plate and just retune it and the bass bar. If not; it is definitely worth making this tool for use in your violin making and adjustment from now on as your primary diagonostic and adjustment tool. You see, you do not even have to know what the subject part tap tone frequency IS; this tool simply tells you it needs to go up or down; and our web side will show you exactly how to move it in the direction that you need; to get it sound in harmony with this tool!
..Now there are certain standards that this tool MUST have to work correctly:
..The plate must be tuned to 213 HZ evenly and all over.
..The bass bar must be tuned to 188 HZ evenly all along its length.
..This is my new favorite 'tapper" tool : {2020 Material : ...} [Really reduces the unwanted high overtones...]
..6 " long and 0.3" by 0.4" cross section, made of split spruce wood with "213" wood tone and # 22 rub tone. (As before, but now split it with a thin metal wedge in the center line; in line with the tree growth rings, into two equal halves.)
..Longitudinal Cross-Section as seem from the side..
..Cross Section in the middle...
..Now that it is split apart, dig out the wood in a mortise shape leaving enough wood on the edges for gluing back together after the hollowed out areas of the two halves are filled most of the way with lead 'bird shot' (fine lead pellets from sporting shops). Leave a little room so the lead shot has some room to move when assembled.
..Now mix up your violin making hide glue and wet all the joint areas and tip the two halves together quickly and clamp in place until dry.
..This "Dead Tapper" will eliminate much of the high overtones which really helps us hear the lowest overtone, which is what we are listening and adjusting our violin parts from...HIGHLY recommended for tap tone tuning!
