Note. I will not be including the making of the neck in this instructable, which on hindsight was the most labour intensive part of the build. All it took was a piece if wood a few files lots of love and care and an incredible amount of time.
Step 1: Parts & Tools
A Neck ( I built my neck out of a straight piece of wood that i shaped until i was happy with.)
A small drum. (I originally bought mine from here. Which was ideal.) Try to look for one with an uneven number of tuning pegs as then there will always be a space where the neck will be opposite a tuner where the tailpiece will go.
Tuning Pegs. (I used the cheapest friction pegs i could find from,
A Banjo Tailpiece. (From Here.)
A Bridge. (From here.)
A Ukulele Nut. (From here.)
Small Gauge Fretwire. (From here.)
And some strings.
You will also need some excess wood for finishing and some wood screws.

Step 2: Attach the Tailpiece
Then replace the existing tensioner with the new one!
