Nut width history 

Hola.

Lots of good reading here about various nut widths. As I am following a Santos Hernandez drawing which uses a 50/41mm nut configuration I've decided to make such a nut and try it out on an existing guitar so I can at least feel what such close strings are like on a flamenco guitar (not too bad for me as I normally play a 335, though rarely in 1st position). That's also quite a gap - 9mm in total - between strings and the fingerboard edge. Seems almost overly generous. It goes down to 58 at the bridge.

Maybe the zeitgeist has changed over the years and a 52mm nut with larger string spacing has become the norm, but why did makers favour small widths (C.Vega ref I think) back in the day do you think? I am worried that 'balance' may have something to do with it and increasing one dimension will throw the thing out!

I'll probably make it as suggested several times as 52/43 but would like to know what you think caused the change (if change there was).

Thanks.

RE: Nut width history (in reply to El Burdo

el burdo--most of the torres guitars and guitars following torres i have seen or read about had nut widths at 52mm. it is likely torres set that as well as 650mm as his standard which became "the" standard. there are a couple of torres at g.s.i. museum that have 52mm nuts and a manuel ramirez with a 45 mm nut. i sort of wonder if the less than 52mm nuts were commissioned jobs--that is, the customer wanted a narrow nut.

RE: Nut width history (in reply to keith

It's a common misconception that Torres "standardized" the nut width and/or the scale length. The majority of his remaining guitars have nuts narrower than 52mm. Most are in the 48-51mm range.
At least half of his existing instruments have scale lengths that are not 650mm with most of them being somewhat shorter although there are a few that are longer, up to 661mm.
Santos Hernandez guitars generally have nuts measuring about 50mm and scale lengths in the 655mm range.
The Romanillos, Urlik and Grondona/Waldner books have these measurements along with a bunch more.
String spacing at the nut can be varied to some extent to suit the player.

FWIW, I have two considerably newer blancas, a signed 1973 Contreras and a 1963 Ramirez (I.M. stamp). The Contreras has a 50mm nut and am 658mm scale length and the Ramirez has a 51mm nut and a 656mm scale length.
And both have real pegs.

RE: Nut width history (in reply to C. Vega

I was thinking more of the string separation. 41mm seems rather close for a nylon strung guitar. And the 9mm spare in a 50mm neck width seemed a lot. Maybe he wanted a significant mass of wood to vibrate. These days it seems 43mm in a 52mm neck is common. Not standard but common?

RE: Nut width history (in reply to El Burdo

Can't help with the history, but I guess that people are higher now than they were 100 years ago (and also have larger hands so it's only natural to make wider necks)?
From my experience I would go for 52/43 with your build. I play fender strat most of the time (which I guess has even narrower neck than your 335) and getting used to 52/43 flamenco neck of my 1st build took me no time at all. Actually, it's harder to came back to strat after playing flamenco for a while than other way around.
Also, from my experience with acoustic guitars the string spacing and the profile of the neck have more impact on the feel than the width of the nut.

RE: Nut width history (in reply to El Burdo

If you're making a guitar for yourself just find a combination of nut width, string spacing and neck profile that's comfortable for you and copy it. It's really no big deal whether you're building a Santos "copy" or not. Be realistic. Chances are you ain't gonna end up with anything even remotely close to a real Santos anyway. Make the guitar, have fun playing it and don't sweat the small stuff.
I seriously doubt that any variation in the string spacing at the nut is going to have an effect on "vibration" or whatever in any way.

Sr. Vega--yes you are correct that Torres did not "standardize" nut and scale dimensions although being the "father" of the "modern" guitar it is easy, albeit erronously, to attribute those to him.

RE: Nut width history (in reply to C. Vega

Mr. Vega - my point is simply that I am using a plan of one of his guitars. I'm not impressed with myself that I'm doing it. But if I alter the dimensions I worry that I will throw its balance out without knowing why - I am not a luthier and I anticipate the forum will have some insight, for which I am grateful, though I am beginning to recognise that more experience is required here.

I may well not come remotely close to one of his guitars but I hope that with care, and by following his plans I may come closer. That is why I am reluctant to deviate. Have you ever thought of teaching as a career? Don't.

I take your points about measurements. I guess I just need to hear them from an experienced maker.

As for 'having fun' playing, I have done that every day of my 30 year professional career as a musician.

Mr. Vega is a wealth of knowledge that many of us "luthiers" value enormously. Please don't insult him. In case you're wondering, I've been building guitars for almost 50 years and playing flamenco guitar for about the same length of time.

Mr Shelton - You've misread everything I said there. Maybe "needed" would have been better, it's what I meant. Mr Vega answered my questions and I am grateful as always - and this is not the place for insults, but neither is it the place for patronising. I don't expect you to agree so I'll withdraw from posting from now on.

I will accept your interpretation that I misread the connotation of your post. If that is the case than please accept my apology. There are very delicate egos to be considered here. A luthier pretty much has his "heart on his sleeve" so to speak so please be a little understanding when one of us sees someone attaching a fellow luthier for no reason.

RE: Nut width history (in reply to El Burdo

Gut strings might have something to so with the smaller nut widths, but then again maybe not. Gut strings feel different and are different in diameter for each pitch needed on the guitar. depending on the set of gut strings the diameter could be smaller than nylon giving a feeling of more space, but of course that is compared to what.

I've made a few vihuelas which are "double coursed", two strings per pitch. The nut widths are quite narrow, without looking at my notes I seem to remember 47mm - 45 mm 48mm as possible nut widths. There is always talk in the early music scene of musicians who play modern guitar wanting to get into lute and vihuela playing and complaining about the narrower nuts. They will often ask for a vihuela to be made with modern nut width that matches that on thew guitar so they can move back and forth from modern guitar to vihuela easily. There are a few problems, mostly that the lute family of instruments, into which the vihuela loosely falls, use a right hand "under-over" thumb & forefinger technique for plucking the strings. It requires you clip your finger nails and use the fleshy pads of the fingers.

So this has nothing to do with left hand, right? Maybe not so fast, it could have a lot wot do with left hand and nut width. Here's why; the way the right hand activates the string has a lot to do with the space between strings at the bridge. One type of technique might be better if the strings are closer together, the example I cited is the over-under lute style, but what about the "classical" guitar in the 19th century? The styles of right hand playing must have been different than they are today. There was one style where the player rested the pinky on the top of the guitar, another where the player did not use fingernails to engage the strings.

Think about all the ways in which those Torres era guitars where played, how they were set up with gut strings and how the right hand would activate the strings in relation to the strings spacing at the bridge. Today's flamenco or classical player would perhaps have a more robust right hand style in terms of arpeggios and picado. Maybe a lot of wider bridge string widths developed as a matter of how right hand technique has become very strong.

There's a funny often missed geometric quirk about the Torres guitar which has basically not changed into modern guitar making. The bass E to treble E spacing on a Spanish guitar bridge is usually equal to the width of the neck at the 12th fret. The string spacing narrows by that proportion all the way back to the nut. So if you come up with a distance you want the string to be from the edge of the fingerboard, like say 5mm on the treble E at the nut, you can project the fingerboard taper by knowing how much distance you want is between for bass E to Treble E.

That all sounds wacky, but here is what is salient, overall nut width may not have been first determined by saying "Hey Tony I want a 52mm nut" the player might have said I want this much distance from string to string, one inch and 7/8". - (Torres used inches not mm, anyway another topic) - or maybe the guitar makers just had a standard string spacing at the nut, they projected back and forth from bridge to nut to arrive at a neck taper. The outside dimension of the nut at the peghead is determined outside neck width. Maybe we've come to talk about it as outside nut width, like 52mm to 54mm, because the guitar has been round long enough to have changed. But whn you speak of 52mm you're really talking about how much distance the two outside strings have from fingerboard edge vis a vis how you project neck taper........... which brings you back to the ratio of body neck join width being equal to that of string spacing at the bridge.

Maybe in Torres' day they were thinking more about string spacing at the nut in terms of gut string diameters. And also that geometric idea that the 12th fret width is generally equal to the string spacing at the bridge and this projects to the nut. ( Yes go to your guitars and measure it. A classically built Spanish guitar will express that ratio!) Also that right hand technique may have favored less string spacing at the bridge and how that effects the way the neck taper ratio works.

Confused? You should be.

So they were not pulling these measurements out of their asses, they were working with the ratio of distance between strings and type of strings, gut and how those factors effected the way people played.

Thats not an insult??? Give me a break!! You've insulted two of the finest guitar builders around and have the guts to say "this is no place for insults" ? If you "withdraw from posting from now on", you'll be doing everybody a favor.

RE: Nut width history (in reply to estebanana

Thank you John. The written word is often opaque and we can all be, and have a right to be sensitive, and for many different reasons. I was back there, so I spoke. Nonetheless, a period of quiet contemplation will be undergone now.

Estebanana - wow. That's very interesting as usual and you have unwittingly answered one of my unexpressed confusions, that of the width of the end of the fingerboard, which 'might' have been indicated in my drawing but might not have been. I've often wondered about the ratios between bouts etc building in Imperial units rather than metric as well. Pythagoras is in there as well as Torres I see.

What strikes me most of all from almost all the posts on all my queries is that written dimensions are quite pragmatic and that common sense is a reasonable way to go as well. Accuracy is important but there's no need to fear the units.

Thanks again.

Out.

RE: Nut width history (in reply to El Burdo

I read somewhere that modern nut widths around 54mm come largely from the influence of Segovia, whose hands were bigger than saucers and whose fingers were like sausages. Nonetheless, he set a precedent and wider nut widths became standard. Most people could comfortably play on much smaller nut widths, I like a 49mm nut with string spacing at 41mm on my nylon string guitars. Plus a 16 inch radius on the fretboard. People comment how easy they are to play but can't recognise the radius. 16 is pretty flat so I can't see any issues with playability over a flat fingerboard.
Cheers
Dom
