Hello David. I don't think that I understand the photo with you routing the binding ledges. Could you explain? I don't think that I've seen it done with the guitar body held vertically.

Hey Rob ... that jig is used a lot up here in Canada ... another example of the influence of Jean Larrivee. Jean made this jig in Bruce West's machine shop back in the early '70s. It's elegantly simple and takes up very little room in the shop ... love it!

Really enjoyed seeing how the arm bevel comes together in the process. Looking great, David!

Care to share some detail on what you're doing here?

What's the SW you're using?

What's the measurement method?

What's the analysis method?

How do you interpret the data purposefully and usefully when building the guitar?

Hi ecguitar ... thanks for viewing this thread! I'm just using Audacity to do my frequency analysis in that photo. I use magnets to simulate the mass of the bridge (shaving about 1/3 of the weight of the bridge/pins/saddle off to account for the stiffness added by the bridge once glued on) ... then record myself lightly tapping the top in the bridge area. You can then highlight the waveform and analyze the frequency spectrum. I pay the most attention to the resonant frequency of the air, the main top monopole and the main back monopole frequencies. Typically, on my Concert Model, I like to place the main air frequency between G2 and G# ... if you place it right on a note, it has too much mobility which manifests as a note that blasts out there quickly but loses a noticeable amount of sustain ... quite noticeable to the player both when playing the note individually and within the context of a chord. Manipulating the main top and back frequencies (and the interval between these two notes) has a sonic impact as well. I talk about these things in a bit more detail on the "Workshop" section of my site.
