Hello Everyone!
             In this Instructable  I will show you how to make a small but powerful sander, that fits right in your pocket. It is made out of components from old, broken electronics. I did not buy a single thing while making this project. The sander is super easy to make and takes less than an hour. Let's make it!

This is great for makers on the go, and fits right in your pocket!!

Step 1: Gather Your Materials

Picture of Gather Your Materials
For this project, the materials you will need are:
  • A small capsule
  • A switch 
  • A motor
  • A spring
  • A piece of sandpaper 
  • A small wheel 
  • A usb cable (male)
I got the switch and the motor from a broken toy car. I found the small wheel on a broken radio. This wheel was used for volume control, and had a small hole that was the right size so it would fit on the motor. The small capsule came from a hair coloring kit (from my mom) The USB cable came from a broken Mp3 charger. 

For this project, the tools you will need are:
  • An Exacto knife
  • A pair of scissors
  • Superglue
  • Electric Tape (not pictured)
  • A Sharpie

Step 2: Prepare the Wheel

To prepare the wheel, start by taking your small wheel and make sure that it fits on the axle of your motor. If necessary, drill a small hole in the wheel. Once your wheel fits, get your sandpaper, scissors, and Sharpie. Turn the sandpaper over and place the wheel on top. Trace out the shape of the wheel on the sandpaper and use the scissors to cut out the shape you drew. Now, glue the sandpaper to the wheel so the grit of the paper is facing up. You have now prepared your sanding wheel! Continue to step 3.

Where do you get all of your small motors!!
Verticees (author)  joe9611 months ago
hey joe96,
I get all my small motors from old, broken toy cars I have. If you do not have any small toys that you can get motors from, try looking online! I know a ton of retailers that sell motors for low prices!

HI,

I am making a Rotary tool at home using a brushless motor and a pin vise, following is a build log.

Looks good! It's a lot more complicated (and it has more features) than the one I made, so it will probably be better and much more functional than mine. Good luck on the build!
what do you do when you want to change the sandpaper?
Verticees (author)  aerotechnic1 year ago
Superglue does not adhere to well to plastic (at least the one I used), so you should be able to peel the sandpaper off and apply a new circle of sandpaper! Hope this helps!

I like the idea of running it off of a USB cord. Cool project!

Thanks! I was originally going to make it run off of 9 volts, but I liked the idea of it being USB powered too!

Thanks for your comment!
Your welcome. I also voted and followed!
Hey, nice job! I did something similar, but put a fan blade from one of those balsa planes. Parents freaked out a little when I used a USB wall adapter and plugged it in to a wall socket. Keep up the good work. I followed.

Hey, a usb powered fan is a great idea!

Thanks for following!
Your idea is really cool. This can be used by modelers, knife makers and other people to do little jobs. You can -and I will try to- improve the design, make changeable disks to polish, sand maybe even paint! You can get a rechargeable battery from a phone or a video player and charge it by usb (I made it with a PS2 joystick). I'm voting for you!

hi faacuunndoo,
I really appreciate your kindness. I am working on another design for this that will look much more professional, but I didn't think of a rechargeable battery (great idea!). I figured out how to make removable attachments such as a polisher, a sander, and a drill. I will be publishing an instructable on how to make them, and I will be sure you get the link. Thank you so much for your kind words. You have made my day.
Thanks.
Remember: the screwdriver started as a flat piece of iron, now there is one in each house in the world! ;)
