Jose Catoira Posted June 18, 2014 Report Share Posted June 18, 2014 I am just finishing the plates on the second of a pair of 5 string fiddles I was comissioned to make. The wood choice was the same for both instruments, fronts came from the same log and backs as well. I have never been trully convinced by platetuning but there is no harm in measuring things, maybe they'll come in handy someday. Both backs were made using the same archings, I was very careful about it. It resulted in a near perfect match of frecuencies and thicknesses. Both backs are the same. Now, the fronts I made one with a very low arch, just over 14mm. I was aiming for a 305hz mode 5 before bassbar, which I got to with an overall thickness of 2.9mm-3.0. Slightlly thicker between Ffs. The second one I am tuning right now, the arch is higher, 16 mm. Wood from the same tree. I am at 324hz mode 5 before bar and overall thickness of 2.4mm. Sacconi numbers they all are. Am I correct if I draw some conclusions from this ? Higher arch, gives me a stronger front resulting in raised tap tones and decreased thickenesses?
