Well we've finished our vibraphone and it's pretty great
But I can't find a good motor. I've got probably the same motor as Jim ($21 from Jaycar) and it's too noisy. Seriously I need to knock about 30dB off. The instructions point to the forum to share ideas, so here I am.
Has anyone got alternatives. I went to the wreckers yesterday to look at wiper motors, as they use helical worm gears, which are apparently a lot quieter. The bloke wanted more than I was willing to pay ($35 to $100, depending on the model). I'd rather get

I've asked the diy robot people, and all their gear motors are similarly noisy, but they suggested an AC motor from a turntable. Interesting idea by I don't know where to start on that one. Might need a double pulley system to get the speed reduction.
In the meantime I might try to wrap what we've got in wavebar or something like that.
Any more ideas? I'm desperate for my kid to play jazz with me, but he insists he needs the vibrato.
Thanks
George
