video DIY Vibration Polisher
So, if your thinking about making this project I would only advise you try it if you already have or have access to the more expensive parts that you will need (motor, springs, hardware). If you had to buy everything new you would just be better off buying a cheep commercially made machine. But if you think you can make it on the cheep and you need a project to take up a weekend, than go for it!
To make the vibration Polisher you will need:
Automotive valve springs X4 new or used. I went with new witch ran me about $9. total.
Drilled gum rubber carboy stopper x4 about $5. total
"J" Bolts with nuts and washers x16, 3/8" to 1/2" carriage bolts with nuts and washers X4, length of all thread rod at least a couple inches longer than your bowl is tall x1, and miscellaneous wood screws, nuts, bolts and washers.
total $10. With some stuff I already had.
Some scrap plywood. total $0.00
A decent size motor. Mine was around 1/3rd hp. x1 total $0.00
Plastic bole with lid. x1 total $0.00
Automotive funnel. x1 total $1.00
Total cost for me was about $25.00 not including the polishing medium witch was another $25.00
I hope this helps someone out there, and let me know if you need any advice if you decide to make your own.
Thanks for watching!
I have entered this project in the ShopBot Challenge so if I were to win the grand prize I would use it to start a furniture and or boat building company. With such a sophisticated tool at my disposal I would be able to quickly prototype my designs, refine them and finally mass produce a finished product. The list gos on in my mind of all the uses this tool would have for me, but mostly it would mean the start of a new career.
Best of luck to all,
Nate D.

Thanks in advance!

Personally I'd try just springing the bowl and leaving the motor fixed. I wouldn't go with the out of balance flywheel either, least not directly connected to the motor. Can't be good for the bearings.
One design that might work (yeah yeah rough drawing I know):
Yea, motors are not happy when they are ran out of balance and I'm sure I'm reducing its lifespan buy doing so. At least its getting used for something at all though.
Anyway, thanks for the comments and the drawing. It's already giving me ideas, I think something like that would work. I would make a 4 or 5 or 6 piston design. The bowl would sit on springs with the pistons arranged in a circle under it. The motor would turn a crank shaft that would drive the pistons into the bottom of the bowl one at a time in a circular pattern. That should give the desired rotation of the polishing medium in the bowl.
Now I kinda want to make that just for kicks. We'll see if I get a wild hair one of these weekends...
Then I was thinking why have a motor at all. AC electric current is supplied at 60 Hz which could be pretty shaky too I'd imagine. Take a big transformer and remove the secondary winding from it and put a metal plate over it separated by a spring. Put what you want shook on top of the metal plate.
Might have to remove the outer transformer arms to get the magnetic field to extend further though. Not like I've ever tried to turn a transformer into a solenoid before.
