How To Make A Ukulele From A Plastic Bottle? – Great Way To Recycle

Making a diy ukulele from a plastic bottle is an interesting and fun way to recycle. It’s also surprisingly easy with just a few tools and materials. This blog post will take you through the process step by step so that you can make your very own unique musical instrument! 

You can then use it in many ways, such as taking it apart again, decorating it, or giving it away as gifts. 

Let’s dive right into this How to Make a Ukulele From a Plastic Bottle guide!

How To Make A Ukulele From A Plastic Bottle?


  • Old laundry detergent bottles, cleaned and dried. We recommend using a 50-ounce bottle
  • Solid pine (15⁄8 x 5⁄8–inches), approximately 24 inches in length
  • Hardwood pins (3⁄8-inch (1) and 1⁄4-inch(2) ), over 4 inches and 8 inches
  • The fishing line of 40, 50, 60-pound type, over 40 inches length
  • Ruler and pencil 
  • Eight small screw eyes
  • Handsaw or jigsaw
  • Utility knife
  • One sheet each of medium and fine sandpaper
  • Wood glue
  • Drill and 1⁄16-inch bits
  • Small C- or spring clamp that opens at least 1 inch wide


Step 1: Fasten the neck to the bottle

  • The pine should be sanded until it is smooth. Mark with a pencil at 434, 15916, and 1634343, 434, 15916, 16316, 1678, 17916, and 1838 inches.
  • After you’ve created the contour of one end, cut along its form using a utility knife. For optimal results, make sure your cuts are flush with the front of the bottle.
  • For the neck, you’ll need two different-sized holes cut out ( about 5 – 6 inches from the bottom opening). Next, in the traced shape on the bottle end at the top, mark where the exit hole should go; slide this through the bottom until 3/12″ sticks up from the rear.
  • Trace a line down the front lower edge, as we will be cutting there later when creating our cork stoppers 😉
  • Take a pencil and a ruler and measure 414 and 434 inches from the neck of the plastic bottle and connect the two spots. Do the same thing at the bottom edge as you did above.
  • Now that you can see the joints that make up the rectangle cut it off using a knife. Return the bottle to the neck and match the bottom of the bottle with the mark you made; you can still see the pencil line at 43/4 inches.
Glue the dowels to the neck

Step 2: Glue the dowels to the neck

  • Take out the ready-made dowel. Cut a piece (1) into two little pieces 158 inches long. You should stick (1) piece to the upper surface of the neck. Slide your fingers through the rectangular cutout.
  • Cut a piece (2) into four little pieces of the same length.
  • Stick a piece of wood (2) along the initial pencil markings in step 1.
  • Stick one piece of wood grade (1) at the 13916-inch pencil mark.
Secure the strings.

 Step 3: Secure the strings.

  • Place the ukulele faceup on a table, with the neck 114 inches from where it should be when secured. Mark this position and then drill three holes close together off of that edge, spacing them evenly approximately 3/8 inch apart for screw eyes that will keep tension without breaking free under pressure!
  • Mark a line 13⁄4 inches from the right end of the neck and drill pilot holes 3/4″ and 11/2″. Mark another line 31⁄4″ in from this edge for mounting screws and drill 3⁄8 inches and 11⁄8 inches from the edge. Screw four screw eyes.
  • Take 36 inches of fishing line and tie one end to the top left screw eye to connect the strings.
  • Then stretch it across the ukulele until there are approximately 34 inches of string slack beneath the right side, with ours up against the bottom nut slot for stability.
  • Next, use a flathead screwdriver or any similar instrument as a guide to ensure that the needle tip passes through both layers: Before threading in the other way, make a tiny notch beneath the edge closest to the hole.
  • Rep, connecting one end of your 60-pound line to each of three pairs of screw eyes. Tie an extra 50 pounds to the first two lines before connecting them at the bottom.
  • You may use the various programs to tune the ukulele. The notes G-C-E-A will be the ukulele’s main tones.
