How can I make this barrel organ idea? Answered
So, I want to make a "programmable barrel organ" like the $1100 version below (called the Gloggomobil) but instead of using a xylophone to make the notes, I want to use kalimba-style metal rods that are plucked by pegs. My problem is, I can't think up a good way to do the barrel. The pins need to be strong enough to pluck these metal bars without breaking, but also secure in their spots so that they don't fall out when the drum is upside-down. The only thing I can think of that would be effective would be a metal barrel with threaded holes that you put screws into, but not only would drilling and threading hundreds of holes be impossibly time-consuming, programming a song would take hours and hours. I've been pondering this thing for the last week and I'm at my wits end. I'm asking the Instructables community to give me a hand figuring out what to do. Pretty much any material is at my disposal: wood, metal or plastic. I want this thing to look good though, so I don' want to do nails in a coffee can or something el-cheapo like that. Thanks for any ideas, I'll be sure to write up an Instructable once work gets underway.
