#49 The Wheel Machine

The Wheel Machine uses a wheel and a chain to send a number of fingers repeatedly onto the piano key. Very clever engineering, Warboys Community Primary School!

Sam’s idea for playing a key is very funny: if people play the piano using their fingers then a mechanism should also have a set of fingers, one after the other! Sam’s pictures shows the fingers on a long conveyor belt, but we couldn’t find the components to make a belt that was long enough and narrow enough to fit in.  Instead, we’ve made a belt about half the required length and the player drives it via a pulley and rope.  The fingers are laser-cut from pink plastic sheet, and connected to the belt by hidden rivets.
