Re: Unusual Panal Size

Thanks for this John, I didn't see your reply until just now. I guess I should have done a search before starting my post. Your info is very helpful.

Re: Unusual Panal Size

Thanks for the re-direct Trevor. I had read that, but didn't correlate the two subjects.

Re: Unusual Panal Size

Thank you Trevor, I looked at that page and it's a section summary, none of which talks about a three point bend test. I also reviewed the panel tap testing sections of both Design & Build books, but could not find any information on this. Could you elaborate more on this three point bend test, or r...

Unusual Panal Size

A few years ago--pre The Books--I purchased the attached four piece book-matched set of Honduras Rosewood with the intent of making two guitars out of it. As you can see, I will not be able to get full rectangular panels for the backs to do analysis for target thickness. Two OM sized templates just ...

Re: Spectrum change with age

Thanks for both of the replies. It's interesting to me, so I'll try to track it over time.

Thanks again.

Spectrum change with age

I was talking with the new owner of my latest guitar about the likelihood of it sounding better as it "settles in" with more use. It's fairly well accepted that as instruments are played more and age, they tend to sound better; or at least different. This got me thinking, and wondering if anyone has...

Re: Spectrum results

Thank you so much for the advice Trevor, you really sent me in the right direction, and your advice was spot on. This is all starting to make sense to me. I strung it up and fine tuned the relief, nut slot depth and action. Ended up with 13 mm string height at the bridge. I averaged 10 plots on the ...

Spectrum results

My guitar is 99% complete. It’s a OM sized, 14 fret, live back, falcate. I did the spectrum with no strings so I could get to the inside easier if necessary (I’m not sure if taking spectrum analysis with strings on or off makes any difference). Bridge with intonated saddle and 6 bridge pins = 25g. N...

Re: Bridge Rotation at 2.3deg

Thanks for the heads up Trevor. I'll look into it. Coming from Alaska makes it difficult, but knowing your travel itinerary, I guess I shouldn't complain. With your connection to Charles Fox, have you approached him to sponsor an symposium? I very much enjoyed the time I spent learning his process. ...

Re: Bridge Rotation at 2.3deg

Thank you both for your replies. I think trying to manipulate the braces in a no-go. And Trevor, you have put my mind at ease. I'll put bridge rotation lower on the priority list. Thank you so much for your books. Such a pleasure to have great and relatively easy to follow guidance in this passion. ...

Re: Bridge Rotation at 2.3deg

If you don't mind, I'd like to jump in here as I've just measured the rotation on my current build last night. The subject is a medium body, 14 fret, falcate (sitka spruce) with carbon fiber per the Books. My 3rd guitar and first using the Gore/Gilet process. The tops (sitka again) thickness is good...

Re: Wood for Falcate Braces in UK

Thanks Martin,

Yours is great too. The ingenuity of the luthier bunch never fails to amaze me. Anyone else want to share their process?

Re: Wood for Falcate Braces in UK

I have had 100% good luck with sitka. I use very precise male/female forms that clamp together and support the wood well. I use three, 1/16" thick plys. The forms were made using a 3/16" diameter, bearing guided straight router bit so they exactly match the width of the three finished plys. I glue w...

Re: Help with my spectrum

Thank you Trevor, Those references help considerably. I'm going to dive back into the books in more detail to proceed, but in your opinion, would you continue to relieve the back brace at this time, or wait until the bridge and saddle are attached? It's not nearly relieved as the books suggest to st...

Help with my spectrum

Hello to everyone, I have completed the box of my first falcate braced guitar and would be grateful to you all for some input/advice on the resonances it has at this point. Some details: OM sized medium body. 14 fret body join. Tzalam back and sides (752 Kg/m3). Sitka top with a bit of bear claw fig...

Hello, my name is Eric. I'm new to the forum, forgive me if this is tired subject matter. I live in Anchorage Alaska and build purely for fun. I have two OM sized SS's completed, the first was under the supervision of Charles Fox at the American School of Lutherie. His class was a terrific experienc...
