Consider a new post or moving it.

It's always the functionality that matters. The player shouldn't feel the protruding nut sides on the index finger. If he does, then it's wrong. If not, it's good.

You've got to start somewhere then go from there. In general I usually recommend studying Sacconi's recommendations for thicknesses. I know that Manfio has been very successful.

I didn't say poor graduation. But you are right, poor graduation is disastrous.

Consider that the air inside the violin vibrates when played and the vibrations are projected out through the F-holes. Mastering how these vibrations behave determines the quality. Thicknesses of the plates is also a contributing factor but less so than the shape of the arching.

The best violin I've ever made (I believe) was made with zero tap tuning. No knocking on wood whatsoever. Just to prove that tap tuning is pseudo science.

Pray.

The upper curve seems a bit odd but it could be distorsion from the camera. The kidneys reminds me of Peter Prier's bridges although yours are a bit more extreme. Overall I think it should work. It's much better than the second one IMO. Personally, I would shave off more wood from the legs. Perhaps you took away more wood than needed? Or maybe just enough. Why are you asking btw? It's also a question of who's gonna play it?

Hello Roger, I'm looking forward to read your novels. Interesting topic. I think it will be a success. Your work have always been high quality and certainly worth a study.

You may be correct about that. I see the rib structure as a means to create space inside the acoustic box for the air to move. I wonder what more you could do with that.

The ribs should match the plates for a fair balance. Just my intuition telling me this, no research.

Andreas, have you done this? It seems a useful experiment.

Is there a European retailer? I believe Mr. Darnton has a pretty good grip on these things...

What brand is the E-string? As I understand it a parchment is foremost to protect the E-string from digging into the bridge as tubes almost always do.

Thanks for the clarification, Davide. I will hold on to the Ponto then.
