One Piece Ukulele




This easy make ukulele is a perfect travel size and it's base is just one piece of wood. This is the perfect project if you have an afternoon off and want to make a cool creative ukulele.

Step 1: Supplies

For this instructable the supplies needed are:

- Block of wood 1×4×16
- Fishing Line
- Large toothpicks or wire for the frets
- Steel or copper tube 4×1/2
- 2 Bic round stic pens
- Ukulele tuning pegs or
you can be creative and make your own tuning pegs like my k'nex ones

- Drill
- Coping Saw
- Ruler
- Scissors
- Pen(this one for writing with)
- Strong multi-purpose glue (gorilla glue or super glue)
- Sandpaper
- Hot glue gun

Step 2: Making the Base

The first thing you should do is draw out the ukulele pattern on to the wood (shown in the picture). It should look like a lond trapezoid 4in. on one end, 21/2in. on the other end, and should be 16in long. Use a ruler and pen for accurate measurements. Then you can cut the base out with a coping saw or hand saw then sand the edges.

Step 3: Creating the Body

Next you can cut out the middle section and sand it. After you can drill two or four holes (depending on the tuners) into both sides of the middle hole to hold the frets in place. The last holes you need to drill is the four holes for the fishing line to go through at the head of the ukulele.

Step 4: Adding Parts of Ukulele

Now you can cut your frets from large toothpicks or fret wire, and cut two 4in pieces from the pens. Then you can hot glue the frets, steel tube, and pen pieces to the ukulele.

Step 5: Tuners

For this step you put in the tuners and I will also show you how I made mine. I used the k'nex pieces (shown in picture) and used gorilla glue to bond them and put them through the tuner holes.

Step 6: Stringing Ukulele

Now you put the fishing line through and can use a tuner or app to tune your ukulele.

Step 7: Your Done

Finish sanding and decorating, then enjoy your your new ukulele!

    Wouldn't it be better to use some kind of resonator like an oil can or something to make a better sound

    If you are going to the effort of making this you should space the frets properly to be able to play a tune.
    Measure the scale length. That is the maximum length of the string between the points where it is touching. Divide this figure by 17.817 and that is the distance to the first fret. Subtract this distance from the scale length and, again, divide the remainder by 17.817. That will be the distance to the second fret, and so on up the fretboard.

    This is important info, and might make this an interesting project for a very portable uke.

    Fishing line won't be the best string, either, though there's not much for a sound board -- what would you suggest?

    Gotta hear it! Where's the youtube video....?

    Thanks for the project!

    Hi, cool idea but could use a little more information ie size of tuner bay and distance from end, a pattern or pdf of fret location for those who have no experience with fret location, and lastly should there not be a nut at the end where the strings are threaded from?

    The exact fishing line i used was omniflex monofilament 6lb fishing line. it was under 3 bucks at walmart, but any monofilament fishing line will sound almost the same.

    do you have a video or sound file of how it sounds?

    Since its homemade you can space them based on your hands, but the largest spacing on mine was an inch and it got to the 12 smallest fret 1 centimeter apart

    I can't tell how you attached the strings, at either end. Could you add more details/photos?

    Thank you for commenting. I actually just tied the fishing line in the holes at the head and wraped it around the body and tied the line to the tuners.
