Cost: $-$$ (Depending on the cost of the paddle)
This project didn’t take a long time, but it turned out to be a really fun instrument. A friend gave me a child sized paddle that was 30 inches long. I decided to give it a 21 inch scale with 15 frets. If you have never made a custom scale fretboard, this fret calculator tutorial will help you get started. I used a zero fret as the nut.
I glued a wooden bowl on the back of the paddle to act as a resonator. I got the wooden bowl from a second hand store. With a forstner bit and a drill press, I made a flat area for the bowl on the back of the paddle. The soundhole was made with a 1.75 inch forstner bit.
String holes were drilled at 45 degrees through the headstock behind the zero fret. Having the four string holes at the desired string spacing, along with the zero fret eliminated the need for a traditional nut.
For my paddle I needed to flatten out the handle headstock before I installed the outside down tuners. On the bottom end of the paddle I drilled four holes for the strings. When I strung up this ukulele I tied knots in the strings and feed them through these holes. Some scrap wood served as the floating bridge.
