This instructible can be helpful to ppl that do little things, crafting, miniature modeling, or like me soldering )) this is just an idea of a miniature grinder that can be remodeled from a bigger fan and used for bigger grinding.

Step 1: Where Did This Idea Came From

Didnt want to put this in introduction, but here just gonna say a few words about it. Was helping my friend to replace a couple of fans on his pc, removed all of them and started blowing the dust of with air, accidently my blower nozle came to close and what do you know )) it hit the fin )) was a close call for not wearing any safety glasses, but at the end i was happy , coz now i have a little thing to modify )) so i came up with High Speed Mini Grinder )))

Step 2: Break the Fins

Well break all the fins away, i happend to have a small nibler, so i cut all fins almost flush , then took a little file and filed at the breaks a better, the more you remove the better balance for the motor it will be, it will not vibrate if you get it all to almost perfect )) well , there is no such thing as perfect, but do your best! Thats what i did.

Step 3: Make a Gringer

I hapend to have a sanding paper, so i cut off a circle for the right diameter of the fan, took mounting tape, it has two sticky sides, cut of the right diameter on that and taped it to the fan using that ))

Step 4: And What Do You Know

You got yourself a simple mini grinder )) use it safe, good luck !

Step 5: Before and After

And thats how it works ))

Step 6: Last Word

For sure this can all be soldered to a switch and power suply, which i will , and will mount it to my soldering station, at the momment i didnt, always short of time )) have fun ppl, thx for reading !
