Hi guys, this is my first instructable, my english is bad, I take terrible photos, so... :)
In this tutorial I will show you how to make a cheap drill.
Note: I found that the diameter of the compasses' leg's are 3mm in most cases. So try to find a motor with a 3mm axle, and the holes on the terminal should be 3mm too. With a 3mm terminal you can use any dremel tool, if you replace the "chuck".
Take apart the compasses, we need the component marked on the picture.
Actually, it is a mini chuck. :)
