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,
