Introduction: HOW TO MAKE a MINI-UKULELE [MINI-UK]
How to make a mini-Uk from readily found materials in craft supply stores. The instrument can be made in four nights by anyone who can drill ,cut and tune a stringed instrument.The instrument is small in size and number of strings. It does not follow the construction of a standard ukulele but uses 3 strings instead of 4.They are tuned to the same pitch as a guitar high strings of GBE rather than CEA of a Ukulele although they can be tuned to CEA if desired. Basically the choice is yours as to what to tune to.
Children will like the small size too.Chords can be played easily over 2 octaves.

Step 1: MATERIALS
FOR INFORMATION- refer to my earlier Instructable "Make a mini-harp from a plastic throwing disk.dated jun.28,2009". That design goes into detail on construction and materials that are used here.
For a quick review -
Resonator Box- wood jewelry box approximately 5x7x 2 in. high. but can be rectangular as you can find in the craft store for about $2.00 . Sand and lacquer as required. Be sure the the bottom is 3 ply not over 1/16 in. thick for good sounding.
Stock and fret board- Can be found finished in a lumber yard . oak or pine. Length can be 6 to 8 inches long.[See Drawing. ] Bridge can be plastic or wood hard board .
Frets if used - tooth-picks .075 diameter or smaller. can also be wire cut to length.
Strings. High polymer cord 1mm. diameterand stretchable to 300% without snapping.
Tuner screws- 5/8 dia. brass plated steel. closed eye hooks.[closed with a plier].
Crimps-Craft jewelry findings- can be round or u-shaped for ease of crimping with a long-nose pliers.Can be 2mm Inside diameter beads.
TOOLS- See picture of above referenced Instructable. [ Pliers, a hemostat and Goop (R) GLUE.]
DRILL BITS- For tuning screw use .093 Diam bit. For anchor holes use 1/16 bit.
TUNING- Can be a Casio[R] or a C tuning fork. piano middle C.

Step 2: ASSEMBLY
STEP 2- Assembly- refer to the Drawing-
Remember that you can vary this outline by using a different resonator box and stock materials.
The basics is still the same. Length of the strings can be to 9 inches here and can still be tuned to the pitch shown due to the novel stretchability of this modern day polymeric material.
The stock can be glued to the side of the box with standard industrial glue or Epoxy. The advantage of this string is that there is very little high stresses on the box unlike that as found in guitars using steel strings.
Spacing between strings- use .35 to .5 in. for a 1-1/4 inch wide stock.
Tuner screws[. See ref.] Close the open hooks witha plier. Apply a spot of mineral or silicone grease on the screw tip and start it into the .093 holes . Turn it all the way to the collar of thescrew then 2 more turns down effectively stripping the thread of the wood. The torque remaining will be sufficient to hold the string tension even after rotating the screw an additional 10 turns clockwise. Another advantage of this string type is low tension so there will be no screw - detuning .
Stringing- Use a crimp bead and attach one end of the string through the closed screw.Then rotate string counter-clock-wise around the collar and maintain tension and feed other end through the 1/16 inch holes in the resonator top.Pull untill the note is very close to the desired value. Then crimp inside. Cut off excess. Final tune upward to the desired note.The note will drift down ward in pitch for the first few hours and stabilize. After retuning upward the note will stabilize at about 1/4 note drift after 5 days of use before retuning.

Step 3: TUNING AND PLAYING.
Tuning- Assembly will be always slightly lower pitch than the final desired note as indicated above. For note drift stability- Retuning at least 3 times, 2 hours apart will stabilize note drift to less than 1/2 note down. All 3 basic strings will drift about the same downward. Final Tuning-
Tuning- Use a piano or Casio . Tune the basic open G in the octave under middle C. Same for the B string. Then the E in the middle C octave [two notes above Cm.]
Finally marking all notes--at G string place a finger nail on the A aboveG note and mark with a pencil at the same time playing that note on the Casio. Continue for all 3 strings. Dont worry about the sharp notes {black keys} as these are found between the whole note marks. If Frets are added then sharps are also frets but this makes the playing difficult due to closeness of the frets. So only use frets for the E open string but only for whole notes. I like fretless playing. Mark the pencil marks when you have cross-checked them. Use an ink pen .Laquer coat the markings so tha they dont wear off in use. Remember- the Middle C note on the G string should sound the same as the C m note on the B string. Same for the E note on the G string should sound the same as the E note on the B string and same as the open E 3d string
Sounding and resonance- The sound and volume can be varied by opening and closing the Lid under side. Have fun experimenting here.I used a one inch diameter hole on top side by making a circle then drill with a .o93 drill close as possible around the circumference then use
a sharp pointed blade to cut out the disc.I laquered the cut edges of the hole.
