Use a old hard drive as a sander.

Step 1: Hard Drive

Remove all the screws to reveal the inside. And then take out all the components. Leave the bottom plate on if you have one.

Step 2: Sanding Disk

Get your sandpaper and trace the platter onto the sandpaper.

Step 3: Glue and Cut

Add super glue and glue the platter to the sandpaper. After the glue dries cut out the platter with a knife.

Step 4: Finish

Put the sanding disk back on.

my hard drive needed the rw arm on to work so i left it there.

Plug in the power to start it up.

Muy buena idea
<p>Good idea, but is the power enough for a sander? Maybe you could demonstrate in a video?</p>
It spins at very very high speeds so there is enough force to sand. You can search up hard drive sander
<p>Good to know</p>
<p>Hard disks normally have 5400 rpm for old drives and 7200 rpm for the newer ones.</p>
<p>Ive done this before and its a pretty handy little tool to have around in the DIY toolchest. </p><p>I will say though that not all hard drives are the same and you will have to find a drive that will continue spinning with the read/write head disconnected. (Thats what I did to mine) </p><p>After I removed the read/write head, I potted all connections not used and the pcb from any access with hot glue so its all sealed and makes it a lot more robust.</p>
<p>really good idea for recycling the old hard drive too bad i see now i dont have my old hd anymore</p>
<p>'' Plug in the power to start it up.''</p><p>Were?</p><p>How?</p>
I meant sata power or molex
