Adding actual movement to a turning is interesting. Adding movement AND sounds seemed something to explore. The simplist way I could think of to do that was to use the "rain stick" idea - a long hollow tube, with some groves in the inside surface and some sticks poked through it - for a bunch of small things to bounce over as the "stick" is turned over, end for end. Could use rice, unpopped pop corn, beans, seeds - or birdshot or ball bearings - or any combination of any of those.
Simple enough - make a tube of some sort, about 2 to 3 feet long, drill some holes for dowels, turn some grooves on the inside, turn some end caps - DONE!
That was the original idea, I have difficulty with K.I.S.S. (Keep It Simple Stupid) - so of course I had to go and make things less simple. I don't want anything other than the wood to show on the outside - no little round circles on any surface from the dowels. That meant an inner and an outer tube. And turning grooves in the inside wall of the inside tube is limited - both by the capacity of a JET mini/midi, and the tools I have that I can cut grooves with - in the inside of something with an I.D. of about an inch and a half.
Then there was the What OTHER Sounds possibilities - bells, twangers, . . .
Here's how this one's gone so far. Will add pages as things progress
