vibratory polisher

Made a vibratory polisher for my daughter to polish her special stones with! the plastic container lifts off so that she can have different polishing medium in seperate bowls, thus avoiding the mess!

Neat job but I for one would like to know what you are doing the vibrating with. Motor and cam? Innards from an old orbital sander (probably not - noisy things)?
Either way, if it works and your daughter is happy with the result I call that a win.

 Hi, it is a large 12v server fan with a hole drilled in one of the blades and a nut and bolt fitted. I started small with a 2ba steel nut and bolt, and will increase the size if it doesnt vibrate enough. Pick a fan with ball bearings as opposed to bushes, as I think the life will be longer!

SwarfnStuff:
Ah, Thanks.
      If I understand correctly the vibration comes from having the fan out of balance by the insertion of the 2ba nut n bolt. With the fan bolted to the underside of the table balancing on the springs it seems to me to be a nice simple and low noise solution.
    Glad I asked.
       Thanks for the reply.

Yup! thats it, and it is very quiet!
