I made my first guitar with it some 20 years ago.

Do not use it for structural joints. Maybe binding, even there I am not sure I would use it again.

Huh... so bigger sound hole equals more bass, is that what I'm reading?

If you read Alan reply:

the larger the sound hole the higher the 'air' pitch will be

Higher pitch means less bass more treble

Surfaces for gluing must be freshly planed not cut

Aluminum tape even better!

Looking forward to hear from your Staufer project.

Sometime, these fans are loud because the air passage is restricted. When running with a lot of "air room" they calm down. This is assuming this is not a bearing problem or vibration problem.

A fan from an old kitchen range hood or a bathroom fan would be relatively quiet and move a lot of air.

If not too late, her is how I do it. I glue my bridge after finishing. My tenor has a scale length of 17 inches which is 431.8 mm I get correct intonnation by placing the saddle CENTER at 434.5 mm form the nut edge, which is 2.7 mm of compensation.

I would say that is too thin (1.5 mm) as you will also do final sanding once the box is assembled.
You could possibly laminate with some other wood, but still you will need to be careful in your sanding to not go through.

Do yo use sandpaper with some kind of backing?

This site has good picture of the bridge.
Not same model but the bridge look similar

Welcome to the forum Alessandro.

So I project the form and the the inner curvature trying to create an inner area where armonicals frequencies can vibrate mixing themselfs armonically inside the violin.

This is interesting. Can you elaborate on your theory or method to achieve that Alessandro

This is not much about voicing, but for a basic knowledge of acoustic there is: https://www.speech.kth.se/music/acviguit4/
Howard Wright thesis is also a good primer to understand all the vibrating modes. Especially the firsts chapters. http://www.hakwright.co.uk/thesis.html
