Earlier I post a link to a way to add actual movement to a turning - that I accidently stumbled on. Thought it'd be interesting to incorporate a bearing I had that was part of a router set. The hope is that the bearing will let the "box" spin - by just blowing on it.
What I hope this gets acrossed is that working movement into pieces isn't hard to do - and is fun. Maybe YOU will do a piece that moves.
Hi Charley,
There are many, I think, which are like me. We enjoy posts like yours here, and we learn from it. Seeing things done which we never thought could be done. But like myself, I have so little experience and knowledge on turning, that while we enjoy the different postings,and do learn from them, we can add nothing, and so say nothing usually.
For myself, I did follow your link and really enjoyed learning how you did this piece. So do not think that just because there has not been
1000 additional postings off of yours, that what you post is not appreciated.And so I appoligise (spell) for not having posted a "I like it" post before now.

While receiving compliments is always nice, what I hope my posts do is show ideas that any turner can do - not to make a copy - but to use the basics of the process and the idea - to create their own unique pieces.
Bowls, plates, tops, christmas ornaments and tops are fun to turn. But there are so many more possibilities that can be done mainly using a lathe. For now, it's actual movement that interests me. But multi center turning can be a lot of fun. There's so much more than just Brown & Round.
Here's the latest Wild Hare Idea I'm playing with.

As always, I find your experiments enlightening. This also.
For your bowl bottom, maybe you might consider a drum skin of some sort. Made of course, to vibrate, and certainly more durable than a styrofoam plate. tom koehler
for the singing bowl references on YouTube -- I look forward to seeing where you get with your singing bowl. What else can yo use as a driver beside the cell phone vibrator?

I was thinking that a speaker, the same diameter as the diaphragm in the bottom of the bowl could drive the diaphragm, if the airspace between the two is closed, by that I mean there is no venting between the speaker and the diaphragm. The small air volume between the two will have some damping effect on the higher frequencies. Maybe the trade-off would be that you have a wider range of frequencies to play with than the fixed speed of a vibrator motor. You could drive it with your HiFi set. tom koehler
I picked up an inch and and eigth, 0.1 watt speaker - cone and coil suspended in a metal frame. The trick is going to be to fix the frame in a wooden ring which in turn is fixed in the bowl. So the bowl, ring and speaker frame will function as one piece - that doesn't move - and only the speaker cone, membrane the cone is touching and the seeds on top of the membrane can move.
The cell phone vibrator puts out a lot of movement - but it produces annoying noises and getting it to put out specific frequencies is tricky. The small speaker can put out any frequency from about 20 cps to about 12,000 cps and it's easy to do that - but it doesn't produce much movement. If I can figure out how to increase the volume - and thus get more movement - the speaker will be the way to go.
May not be able to get this idea to work - but it's been interesting to play with.
