Turn your Junk Hard Disk into a tool grinder

Greetings,

Turn your junk hard disk into a tool grinder!

note: this not my original idea, this was already featured here in Instructables before. 

I just want to submit my own version. I also found out not all Hard disk can be converted to a grinder, some won't spin when you rip out the read/write head, while others, motor are too weak and stop spinning when load is applied.

So far, i discovered that a Seagate Barracuda 3.5 inch desktop hard disk has a strong motor and spins at 7200 rpm. I used the 20GB and 40GB model..

Just follow my pictorial instructable here if you plan to make your own.

Step 1

Tools needed:

1, torx screw drivers set
2. Phillips screw driver
3. sharp x-acto knife
4. pliers if needed
5. clear goggles - for eye protection 

Parts needed:
1. Old Seagate  Barracuda hard disk drive
2. Different Grit water proof sand paper (floor sander paper recommended)
3. Power supply - 5volts/12 volts, the one used for external drive.

Thanks Mhkabir for your contribution!

@a_traceur, yes, thanks for the suggestion!

Great idea! Although I might add something important. I've found that with the types of drives I tested it on (luckily I had multiples) if you remove the read/write assembly the motor will stop working. What I did to fix this is just snip off the ends of this assembly and leave the rest in place.

as for the power supply, i got it from our local computer supply, that one t hat came the usb to ide cable... not much pressure can be exerted, just enough to sharpen my x-acto knife and some marking awls...

Great idea. If you used velcro on the platter you could then use the velcro style sand paper.

[profpat]

velcro style sand paper! yes, that would be an easy task...thanks for the suggestion...

Hey this is pretty cool . . .how much weight can these take though . . .i'd expect that a little too much pressure would throw it outta whack no?

Where did you find that power supply?
