There should be, but often there is not.
I repaired a 70's grand Bouche can't remember the brand which was severely distorted around the soundhole resulting in very high action.

Re: Lefty Build
You would not want to wire audio taper pots in reverse. It would be useless.
You can get the Lefty Pots from these guys

Re: Acoustical effect of back woods

Re: Twisted Ringed Gidgee
If the blank is overthick and oversize as they mostly are, cut it to length and width (to minimise the amount of twist you have to deal with) then flatten one side and use that as a base to thickness to final. The exact process will depend on what gear or machinery you have. Dealing with it this way...

Re: Old build, dead guitar
The guitar may just be overbuilt with a top which is too heavy and stiff.
You can't really tell just from a tap spectrum unfortunately, and tapping the back is fairly irrelevant.
You would need to do the deflection testing and uncoupled testing tap testing.

Re: Testing existing top and back
I'd suggest you just use the existing top and back at current thicknesses, brace and assemble and then test. You can always thin the plates in situ. The results from static testing of a shaped back and top are going to be suspect and can't just be rectified my averaging the width as suggested. For o...

Re: Testing existing top and back
If you are testing "existing top and back" disassembled from the body as your title implies, all the regular material testing methods will not work since they rely on using rectangular uniform pieces.

IMHO length is vital,
A 16" beam with 320 grit is far superior to a shorter file, even if you get a good one.

Re: Interesting intonation problems with two small high-performance guitars I just completed
A few comments, When testing for body, top and back, forget about plugging the soundhole, it's the open soundhole frequencies and only from tapping at the bridge that matter and these are the ones which can put off notes nearby. In the Gore method, the plugged soundhole results are only used for mon...

Looks like he is basically making dobros or banjos with a wooden soundboard instead of a metal cone/skin head.
I'm not to impressed with his dismissal of the rest of the luthiery world, though perhaps that is a product of editing down to a short clip

Re: Need E4 string for 500 mm length.
If you really need to get down to 10lbs tension, then a 16 is going to be too thick A standard guitar scale is 650mm more or less so a 500 scale length would end up midway between the 4th and 5th fret. 5th fret on the second B string is E, so selecting a guitar B string with a 10lb tension will get ...

Routing and inlaying like that will leave a vulnerable area at each edge of the channel.

I'd be pulling the frets, get them too hot to comfortably touch with a soldering iron first, then the CA will release. What do you mean by "a 12" compound radius". If you truly have a compound radius, matching fret press cauls to the board radius all the way is difficult. Using the hammer is fine, b...
