This is a simple electric sander that you can make at home if you have a small 12V drill machine, the one used for printed circuit boards. I needed a small handy sander for a project since sanding manually with hands is time consuming and difficult sometimes. Moreover, it works great with metals too, and it's made from all old parts, since my drill is pretty old too now. So lets start.
Step 1: Things You Need
12V electric drill
Some metal sheet (I used an old cookie sweet box)
Sandpaper (You can use any grit, but for metals and material removal, use 100,200 or 300 grit)
Old toy wheels and a steel rod. You can use a steel rod that comes as an axle for the same wheel. I used an old cloth hanger, and a toy train wheel.
Step 2: Cut the Metal and Join the Wheel
Now cut the metal sheet in a circle, slightly bigger than the wheel. Cut the sandpaper to the same size. Keep the diameter about 2-3 inches according to your requirement. Join the wheel with the steel rod to the metallic plate. Just use superglue to stick the two together. Make sure to mark the center before doing this.
Step 3: Cut the Sandpaper and Stick It On
Now cut the sandpaper in a circle same as the metal sheet. Use double sided thin tape to stick it to the metal plate since it can be reused, or just use any adhesive.
Step 4: Sand Away...
Start sanding. The drill is a little low on power but gets the work done, without spending extra money. Just change the sandpaper when it gets worn out!
