Hi,

 

I am aware that to tune a six string as the scale gets shorter the strings either have to be tuned to a higher pitch or the strings need to get fatter.  I managed to tune my uke to DGBE by using hard tension classical strings from 2 strings over (low E used for D, A for the G, D for the B and G for the highE) and this works well on the 14 inch scale.

 

I recently picked up a cymbala/lap harp off ebay which uses 40 gauge piano wire and was thinking of trying to make a short scale fretted travel guitar with 6 strings with as small a scale as possible using piano wire - thickest I can easily get is .051 diameter (size23).

Available sizes are  

Available diameter sizes of wires:-

  • Size  00        .008
  • Size  0          .009
  • Size  1          .010
  • Size  3          .012
  • Size  5          .014
  • Size  6          .016
  • Size  7          .018
  • Size  8          .020
  • Size  9          .022
  • Size  10        .024
  • Size  11        .026
  • Size  12        .028
  • Size  12.5     .029
  • Size  13        .030
  • Size  13.5     .031
  • Size  14        .032
  • Size  14.5     .033
  • Size  15        .034
  • Size  15.5     .035
  • Size  16        .036
  • Size  16.5     .037
  • Size  17        .038
  • Size  17.5     .039
  • Size  18        .040
  • Size  18.5     .041
  • Size  19        .042
  • Size  19.5     .043
  • Size  20        .044
  • Size  20.5     .045
  • Size  21        .046
  • Size  22        .048
  • Size  23        .051

Like the cymbala I was thinking of using 1 gauge of wire to tune for 2 strings (tuning peg upto wrap around pin and back to other tuning peg).  I was going to stick to standard guitar tuning EADGBE and was hoping somebody out there could give me an idea of how short a scale I can use?

 

Regards,

David

I assume you don't want to learn new chords names but this instrument I call a ukitar uses the same same chord shapes but like a regular guitar being capoed at the five fret. A D chord becomes a G chord, four full steps. The scale is 14.75 " Twenty inches is a good length for a travel size if you use very heavy guage guitar strings. .011 to.048 Heavier the better for tension feel. http://www.palmguitar.com/html/models.php

Why the piano wire???? Get a set of heavy guage guitar strings and be done with it.

Would this help? You can trial-and-error your low E. I got 44 gauge for a low E at 19". That is one fat string!

Oh I forgot, David the cymbala is a plucked instrument, not fretted. Trying to use the same guage of string for two notes a fifth apart is well, how do I say this........a very bad idea. Hammer dulcimer ok, fretted instrument horrible idea.
Diane, I use .048s on all my short scales, they play like butter. It's all relative.

Thank you Diane for the link to the strothers.com - I have had a play around with it.

...And a big thank you to Don for the helpful information.

What set me off on the idea of a ultra small scaled guitar was a video Roosterman posted a while ago of a mini 4 string guitar http://www.cigarboxnation.com/video/the-totally-awesome-mini made by Gakken http://www.japantrendshop.com/gakken-mini-electric-guitar-p-834.htm...
so I was thinking about what is actually possible with regards to playable size (basically with a fretboard below 14inches the frets get too close together for me to play easily) and thickness of string needed for the smaller scale. It looks like to get the full 6 strings EADGBE a 16inch scale may be a more workable option.

Don - am I right in thinking the cymbala idea fretted doesn't work because the strings are too rigid to fret easily and/or at such a small scale you would get major intonation problems?

The idea behind piano wire was a really cheap material to work with - although looking at the available guitar string sets with nice fat strings I realise there is cheap and then there is fit for purpose :O) I must admit though I like the idea on the cymbala where one string is used to tune to 2 different notes using a zither pin-string anchor-zither pin arrangement.

Hi Swampapple,

There is a recent post here where someone had a similar problem http://www.cigarboxnation.com/forum/topics/how-to-get-more-sustain which might give some ideas. If this is no help you might be better adding a new post to the forum giving more information - strings used, type of box, material used for nut and bridge and photos - everyone loves photos. A new thread would open the discussion up to everyone as those with no interest in small scale instuments are likely to read it here.

Regards,
David

i have a 19 in 3 string sounds dead any sugestions?
How anyone can call that electric ukulele a guitar is beyound me. But people misname things all the time. bleh.......Good luck building a 16" scale guitar using only three gauges of strings. One string will be floppy the next very taunt. Not the kind of guitar I'd be interested in playing. Difficult to play, why? Save a couple of bucks? Guitar strings sets are designed to have close to the same "feel" sheesh, why mess with centuries of evolution of the musical instrument. I'm all for inovation but to me playability comes first.

A good point well made Don.
Ha, Found a picture of of another acoustic ukitar I built. Notice how steep the saddle slant is? Needed for intonation as the shorter the scale the more critical fret placement and bridge placement becomes. Plenty of room for inovation in building. Inovation? Check out my pop bottle ukulele. Both bottles have tire valve stems and are blown up with air. Kind of a banjo uke sound. I know I've never seen anything like it.
David, before I forget, I measured a regular guitar neck at the fifth fret and made that my nut width for a wider fingerboard. Pretty cool, huh?

Thank you for sharing this Don - it is the first time I have seen a uke like this!.
It puts the Gakken "miniguitar" to shame. I have seen a few larger sized travel guitars with a similar design and have wondered why they run the strings around a bar and have the tuners part way up the body? Is it simply to save a couple of inches that the machineheads would add or does the extra bit of string mean less string tension overall?
