My goal was to make an electric string instrument that uses drone tuning. I don't know anything about music theory, but drone tuning is a way to tune an instrument that makes it sound good no matter what you do with your fret fingers. Sitars, some dulcimers, and bagpipes use drone tuning. The clubhouse strummer uses GDG tuning (the Gs are one octave apart). I copied the fret layout from a strumstick, but I could have used this handy mountain dulcimer fret calculator to figure out the fret spacing.
Because I don't have many tools, and I hardly know how to use the ones I already have, I didn't try to make metal frets. Instead, I simply used wood matchsticks for frets and epoxied them at the measured and marked spots along the neck.

I used a set of ukulele tuners (now I have one tuner left over to make a one-string electric bass), and the three highest strings from a package of baritone ukulele strings.
I made a lot of changes along the way. For instance, I was able to shorten the neck, and I hollowed out the area for the tuning posts, rather than just drilling three holes. I think it looks better this way (see photo above for way it looked earlier).
I'm pretty happy with the way it sounds. I'm looking forward to applying what I learned when I make another one.
Here's a sample of the way it sounds without amplification. (I used my iPhone to record it. It sounds better in real life, I swear!)
