bob How to tell a violin by outlook if it was constructed by BOB or inside mould

[Mr.Tung]

As I read some conversation here, I found some of the experts can tell if the violin constructed by BOB or inside mould by a just a photo.

I wondering how and which part of the violin can tell the method of the construction.

Just curious and would love to learn about it.

 

Thanks

It’s the ribs.

The corner blocks and rib corner joints are two big clues.  Pay attention to Jacob’s description of these.

One photo alone won't be enough usually. A typical bob construction can be detected by the pinched together rib joints, but a mitred joint could mean a lot of other construction methods, also built on the back around preglued blocks.

BOB can be obvious, but not always so.  Not built on inside mould can be obvious in many cases.

Not all cases are obvious.

 

( In my humble non expert opinion on this matter. )

Thanks everyone! I would like to know which method is better for an old violin? in term of sound and stability?

Or which method is more popular?

Neither is better or more popular - it depends on where the violin was made.

Great violins and terrible violins have been made with both methods, also outside mould and half mould.
