Re: Downdraft table - suction?

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.

Re: Downdraft table - suction?

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

Re: bridge placement

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...

Re: water based finish over linseed oil

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...

Re: Did I plane my sides too thin?

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.

Re: Intro

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

Re: Good reads about flat top guitar voicing

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

Re: Resonate Frequency Problem ?

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.

Re: Resonate Frequency Problem ?

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...

New Spectrum Analysys Software: Beta Testers wanted

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 ...
