DIY Miniature Ukulele

Assembling a DIY guitar with ukulele conversion
BIG BRAIN SCIENCE
BUILD A MINIATURE DIY UKULELE FOR SCIENCE EXPERIMENTS

This is the first installment to describe our DIY kit assembly of a very tiny miniature guitar that will be converted to a ukulele for Big Brain science. This tiny instrument fits in one hand and can supplement the larger Quantum Uke, potentially reproducing a larger range of upper octave scales.
Punch-out shapes on 4 balsa wood sheets
Photos are the best guide for assembly
This "made in Taiwan" kit is in half English and half Chinese languages. Instructions are on the box and include a very general overview which is not intended to supply any significant detail or useful information for assembly.

You'll need to refer to the photos and try fitting the pieces. This is where a complicated point arises. There are several pieces that do not fit.

The insertion tabs are over-sized so these need to be trimmed and sanded. The diagram shows the punch out parts found on the four balsa wood sheets.


This section was modified
The tiny photos (use a magnifying glass for viewing the details) may be the most helpful during assembly. The enlargements presented here may be helpful. Note, the guide for string the guitar strings was abandoned as this section was originally non-functional. White wood glue, like Elmers Wood Glue, is not included. We had the Chinese translated to English and again the wording was not useful for assembly - so don't be too concerned over this. Just follow the photos.

Use extra care in punching out the parts. If any sections are difficult to remove from the surrounding balsa wood sheet, remember to use a sharp tipped hobby Exacto knife. Note the section that was modified, to provide actual string tuning pegs. These are small screws fit into glued left over wood pieces. We also substituted taught rubber bands in place of the supplied thread.

Tiny guitar conversion does not need six strings
A Uke has 4 strings and a classical guitar has six. This instrument also works with one string fingered like a violin. Replace the thread with thinner, smaller taut rubber bands. Cost for this project is $6 for the kit, $1 for the glue, plus a Mass Railway Transit fee.
