Top Plate I

I’ve just finished the shaping and thicknessing of the archtop mandolin’s top plate. The external profile takes a long time to shape: checking against templates, shaping the re-curve, ensuring symmetry etc.etc! But carving the internal surface is much quicker as “all you need to do is” check its thickness with callipers.
At the same time I’ve been trying to record some of the top’s physical attributes to allow for objective comparisons when the next one is built.
Here I’m using a dti to measure the deflection when a 1kg mass is placed on it: this will give me an idea of the top’s stiffness.
