Shaping the Front of the Sound Box

After the sound box pieces were glued, I decided the front of the sound box where the long side connected to the pin block needed to be cut off and rounded to make the design more pleasing and unified. The curve at the front of the instrument would repeat the curves at the back of the instrument and the instrument would also be more comfortable to hold. The straight front of the sound box was cut off at an angle with a Japanese pull saw and then sculpted by hand with a file and sandpaper to smoothly join with the curved front piece.
