Recycled drum machine?

For a while I’ve been thinking I need to have a few more up tempo songs or just a fuller sound to my devopelping set , when I went to the shed to unpadlock my bicycle at the weekend I realized how many old bike frames ,wheels and parts I had in there I got a flash of inspiration! Well maybe only I would look at this pile of scrap and think mechanical drum machine! Not the giant one like James Taylor used on stage but one more the size of my rotary speaker. A search on google shows a few but they are all electronically controlled and have solenoids (electro magnets) operating the drums, cymbals or what ever but I think that is cheating a little and it isn’t so obvious to an audience how it works, I rather something that is a piece of kinetic sculpture. I’m thinking more like a bicycle wheel with bolt heads sticking out around it lifting and dropping rods, I could even have a derailleur on it to change the speed! It doesn’t need to be able to play more than one or two rhythm variations as I’ll only use it for a few songs. I remember as a child of about five being memorized by a 5 minute film of this huge 20 foot tall kinetic sculpture on Play School and somehow I feel that since digital music and the lack oa spinning disc or hypnotically revolving reels something has been lost, it’s all a bit sterile. Anyhow it fits in with my eccentric inventor image! I’ll keep you posted of course if this idea develops into anything more than just an idea.
