A cookie tin banjo has been on my 2do list for a while now. Finally got on my butt and made one. Who am I kidding, I was sitting down already. Partly inspired by Pete Seeger's passing? Anyways, the banjo was invented by people making do with what they had and could build themselves. The cookie tin was commonly used as a banjo resonator. So believe it or not, this is a legit traditional instrument. I planned on making something that looked half-assed but would (hopefully) sound amazing. I sorta got it backwards haha. Some build info: The cookie tin was full of cookies when I got it for Christmas. I don't remember who gave me this particular one. I have a few. The neck is birch I had cut for a different project and this piece was left over. The nut is carved from a shed antler I found. The inlays are elk hoof from a friend's elk a couple of years ago. The bridge is chokecherry. The pegs are forks cut from saskatoon (serviceberry). The tailpiece is also antler. The frets are #10 copper wire hammered flat and carefully filed. The strings are dacron B50 bowstring, 1, 2, and 3 ply. A couple of coats of boiled linseed oil finish it off.
I wasn't real happy with the sound though. It sounded like what a doubter would expect it to sound like. Pops, buzzes, clangs, and crashes, depending on the note being played. Chords were especially terrible. I noticed the distortion diminished if I kept my pinky finger pressed in a certain spot, though, so after a couple of failed remedies, I decided to bend some brass nails into hooks and mount them through the face as shown, tensed by rubber bands. It was a resounding success, losing none of the volume, but increasing brightness, consistency, and especially sustain. It actually sounds very close to how I was hoping it would sound.
I hope you enjoy! As a project it involves a similar skill set to bowmaking. I only used a belt sander to fair up the fretboard, and a drill and palm sander were the only other power tools I used. Mostly drawknife and farrier's rasp.
