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.


-DC motor
-Terminal block

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".



Not necessary:
-Electrical tape

Step 1:

Take apart the compasses, we need the component marked on the picture.
Actually, it is a mini chuck. :)
<p>what type of compasses is that?</p>
<p>the terminal block is a good coupling and worked alot in my projects.</p><p>i always have problem with making screws short.</p><p>i made mine just for taking photo and put in your instructable :D</p>
<p>my drill vibrate too</p>
my drill can not poke a hole in popsicle stick an vibrate more can u resolve
can a wall driller or wood drill can be mage with this attachment pls reply
<p>nice idea..</p>
<p>awesome idea.....it helped me alot....</p>
This is an amazingly helpful instructable

<p>Really super i ll search 4 this type method last 2 month ,,,thanks</p>
<p>Thanks I have been looking at something like this for a while now.</p>
<p>This is a ideas interesting</p>
<p>Here is the method I used to attach a micro-chuck <br>to a motor. Maybe it will work for this project. </p><p>See the Instructable: http://www.instructables.com/id/Micro-Drill-Press-revision-A/</p>
<p>I made it, i try to find the compasses but i couldn't, so i try to made the same diameter the two things and it drills pretty sweet, regards from Quetetaro, Mexico.</p>
<p>great idea, just made mine</p>
<p>where i can find that terminal block thing? is there any appliances or a gadget that has one? please reply i making my version of there which not just a drill but a dremel also. but i'm stuck with the terminal block because i cant find that thing... any help?</p>
<p>man it is found in all hard ware shops </p>
Love this instructable! Lots of ideas. Where did you get the compass?
<p>Very nice work. Once again we see necessity being the mother of invention.</p>
<p>Very clever and well done!</p>
<p>You need someone to 3D print you a cover for the drill! GREAT job!</p>
<p>I like your idea, very clever..</p>
<p>Good job! I will probably make one of those myself.</p>
<p>Congrats!</p><p>very clever shaft-coupler adapter!!, it&acute;s an instructible on itself..</p><p>Mad Max would be proud indeed..</p><p>i&acute;ll make one as soon as i can</p>
<p>I added three more steps, I guess it looks better now.</p>
<p>Nice work and Congrats on being featured on Hackaday.com </p><p>http://hackaday.com/2014/03/16/diy-mini-drill-would-make-mad-max-proud/</p>
<p>Nice idea. But doesn't it make problems with not centered axles? Because this terminal makes not self-centering connection, and if the compass part is smaller or bigger than motor axle it might be not centered and might strongly vibrate.</p>
<p>You're right. My first drill was vibrating like hell - because the compass' leg was smaller than the motor's axle. But now both of them are 3mm in diameter, and perfectly fits in the terminal blocks hole.</p><p>And about the terminal, so far It seems to me it doesn't matter.</p>
very nice. innovative. maybe you can extend it further by adding a handle which houses the batteries
<p>Very nicely done (and your English is better than many native-English speakers - sad, but true.)</p><p>I really like your idea for the chuck - that was a brilliant piece of imaginative engineering.</p>
