Yes, get some oversized pins.

Re: Bridge rotation too high... countermeasures?
On some of my classical with tops close to 2 mm I can see the the main falcate braces through the top. I have not had over rotation of bridge, except one time I found the bridge was lifting off the top on the trailing edge.

Re: Falcate Classical #2 Build (in NZ)
Nice, I love the rosette design. I have yet to make my own classical style rosette. Are you showing how it looks when all are stacked during installation or is that one, two or three tiles?

Re: 1. falcate braced classical
Jurgen, It looks like your classical falcate braces worked out. What attributes of the sound seem different? My falcate guitars all have a characteristic sound that includes long sustain, clarity of each note played and a balance across the strings. Richard, I personally am happy if I have some brid...

Re: Double V Neck Acoustic
Wow, amazing that you built it and really good work in the construction. It seems like it would be a bit awkwards to play, unless there was a right and left hand couple playing it together.

Re: Wood bending fail - looking for advice
I also bend as hot as my iron goes. I have found as you mentioned the wood becomes plastic relatively quickly with a very hot iron. I have also found it possible to cook the the wood such that it takes a rather brittle set. There is a lot of gluing service so you may be able to use CA. A fix might n...

Re: Guitar bridge as a brace
Adding the bridge to my falcate braced classical guitars without a lower transverse brace raises the top frequency (T(1,1)2) nearly 10 Hz. My bridges are generally around 18 grams. So the bridge in this case has added enough stiffness to the top to more than make up for the added mass. I haven't use...

Re: french polishing courses/tutorials?
Robbie has a French Polish online course; it is much like the Milburn method but optimised. The best FP finishes I have seen are not really French Polished. It is the slow application of shellac with a FP like pad (no oil) over some weeks. The surface is leveled every day or couple of days. When the...

Re: Advice on removing HHGed binding
If I am not saving the bindings I just pretend they are not there and recut the binding channels with my binding jig. If I want to save the bindings I start at one end and use a heat gun and a spatula to gently work the bind off. I just work along the binding heating and removing.

Re: Classical Build (s) - Hopefully falcate!
Careful with the methanol it is very toxic, even the fumes. In the US cheap denatured alcohol is about half methanol. I avoid it for pure ethanol as I do not want to wear a mask through all the time it takes to French Polish. Methanol is highly flammable and toxic. Direct ingestion of more than 10mL...

Re: Classical Build (s) - Hopefully falcate!
The guitar looks good. I also wonder about the consistent lack of T(1,1)1 on your plots. I just wonder in you setup something is filtering out the lower frequencies. It should be showing up very clear. You can hum into the box around the frequency you think it is an hear where it resonates. I have f...

Re: Establishing the target plate thickness for Flamenco guitars
I had a very good Flamenco guitar in my shop with the back having a lower resonance than the top; a very thin back. I used Spanish cypress and use the same back vibrational stiffness that I use for classicals and pitched the back for semitones from the top. That might not be typical for a flamenco. ...

Re: Reducing BOBO neck weight
Just a thought, not my idea as it was posted on this site awhile back. Set things up so that you can install the bolt on neck sans fret board before gluing on the back but after gluing on the top. Then while gluing on the back you can set the forward angle by tilting the bolt on neck to the correct ...

Re: Reducing BOBO neck weight
Am I right in thinking that the 'wedge' for the BOBO classical neck might not be required for a flamenco, where the desirable saddle height is 7-8mm, rather than 10-11mm for a classical? I think you still need the wedge. Just imagine flat, no neck angle, with a 6 mm fretboard 2.5 mm of action will ...

Can anyone explain why a Ukulele should be tapered? Is there any Acoustical reasoning behind this, or is it just traditional? . They do not need to be and many traditional ukulele's are not.

Re: having a go at spectrums
They look sort of noisy to me, like maybe your mic is clipping. You might turn down the gain. Because of the extra peaks I can not tell what the back might be.
