Welcome to the forum Ken!
You will meet great people here!
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 use a 1/8 ( 3mm) saddle so this give me +- 1.5 mm...

Please consider that linseed oil will turn quite yellow over time. Just like 'old oil paint' was doing in the past!

From the manufacturer/seller web site: Apply the initial coat to finely sanded wood, at least, 240 grit. Apply with a brush, soft cloth or rub in with 1200 grit wet and dry paper. Leave to cure for 5 to 10 minutes, or until sticky. Rub off the excess with a clean cloth and leave to cure completely b...

LSA is now available for Mac users. You can find a copy Here: https://drive.google.com/drive/folders/1oGqALjZbIEzcvmBvFxp87wma6DI_mu6z?usp=sharing Please consult the readme file for instructions. This has not been tested intensively, please report any problems. The windows version is still available...

From product info: «E6000 is formulated to meet high performance industrial requirements. The self-leveling formula forms a powerful bond with most any material and will remain flexible once cured. E6000 Industrial will handle just about any project DIYers or PROs throw at it.» This would be almost ...

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

I'm using duck-duck-go for the search engine.

That might be the problem. Just type you search in the MIMF search box! Not in your browser search

Works for me 100% Win10 + Firefox

Update: I have made several additions/improvments to LSA. It now come with an installer , which may make things easier for some. The "sound shape" graph is now saved with the spectrum. The cursor now show the frequency in the status bar, the decay/duration can be measured with a left click, Etc. You...

I made one such software also and if you own a PC with a microphone you can download a working copy from here:

This will help you decide if you should try to go up or down with your frequency change.

Here is my 2 cents: Seems to me that the B4 is also one of the frequency of the instrument or the Helmholtz and therefore cancelling the note. You need to shift this frequency of the instrument a little bit. Try blocking the sound hole. Does is also cancell? If not may be changing the sound hole siz...

Hi Chuck, the software will acquire the microphone signal from you PC or Laptop. If the mic is onboard or USB or connected to the soundcard . As long as you have a valid sound input device in windows it will list it. After that it does an FFT to find the frequencies and displays it as a graph and va...

As Barry said.
This is designed to measure the response to a tap rather than generating a signal.

I have been building guitars as a hobby for the last 17 years. A few years back, I started to use Audacity and later Visual Analyser (VA) to find resonnant frequencies of plates and instruments. The many steps one have to go through to get a usable spectrum lead me to make my own software. Over the ...
