Intro: Homemade Mini Dremel Tool
This is my first instructable... hope to like it :)
I wanted to buy dremel tools but they are very expensive, so I decided to make it myself, mixing ideas from more sites, images, yt videos etc.
The good side of my instructable is that the dremel works, but unfortunately it has a bad side... It is about the dremel parts becouse I did not buy any of this parts and its harder to explain where you can find them.
So the parts would be:
-12V, preferable not under 100W electro motor with a 3mm axis diameter;
-12V, 2-2,5A power suply;
-2 wires (non important lenght);
-momentary swich (creators choice for its best performace);
-1mm canvas for sander;
-1 coupling (3mm wire connector)
Step 1: Making the Dremel Canvas
make a circle with the divider on the piece of canvas and cut it with scissors.
After cutting the circle drill a hole in the middle of it. (make sure to be very passent with the 3mm screw)
Tighten the screw pretty hard through the hole.
Step 2: Connecting to the El. Motor
I left the gear on the motor becouse of its lenght for better performance using.
Tighten the coupling on the motor and canvas.
For less vibration in use, make sure to shorten the two screws on the coupling.
Step 3: Connecting the Swich and Finishing
As I said, the swich (preferable momentary), is creators choice.
For this step I didn't find a swich, so I decided to make it.
The (-) of the motor is now connected to the case (see on the second photo) so ever touch on the case of (-) pole from the suply will start the motor.
The screw (swich holder) is isolated.
You will have problems with the centering. To solve it, you have to put some little cuper cutted layers into the coupling. Once you center it, you will like using it. So that would be all, hope to like my first instructable and sorry for the bad english.. Im from Serbia. :)
