Introduction: DIY Grinding Machine by HDD(hard Drive)
Hello! This is my first Instructable, and English isn't my first language(I'm from Taiwan(R.O.C)!!!). So please give me some comments to tell me how to make it better. Thanks!!!
The progress is pretty simple, but the product is really amazing.
Material: HDD, sand paper(roughness depands on what kinds of grinding you want), double-side tape
Step 1: Disassemble the HDD
You have to take the read/write head, magnet off. What's left is the case, major motor, disk, control circuit .
Step 2: Placing the Sand Paper
Cut the sand paper into the matching size of the disk(mine is 3.7"), and one on top.
Then stick it on the disk by double-side tape
***The tape must be put balanced well, or when it turns in the high speed, the motor may be damaged or the sand paper may fly out***
Step 3: Protecting Shield (Optional)
The shield is used to protect things from flying out and hit you.
I made it by two aluminium sheet from two soda cans.
Step 4: Power It
You can simply power it by the PSU from computer.Or make a control circuit by your own.(There are many good ones in Instructables)
***ALL CONNECTION FROM THE PSU SHOULD BE REMOVED OR IT MAY DAMAGE YOUR PC***
Thank you for your reading!
