The EPG is, "Echo1 Pen Gun". This Pen gun shoots BB's and almost anything that can fit inside the Pen Gun smoothly. Unlike other Pen Guns, this Gun can be used as an ordinary pen, using it to right your English Essay. Spring powered this classroom riot device, it can shoot 15 feet with ease considering it is shooting a BB.

Step 1: Equipment and Materials

- hot glue gun

- pliers

-paper clip(forgot in image

- knife

- hack saw or scissors

- Bic pen

- Filer

- Sand paper

- Springs

Step 2: Step 1

Disassemble the pen so that you only have the tube.

1. Remove the yellow tip from the blue connector thing.(the yellow tip is connected to the Ink tube.)
2. Remove the blue connector
3. Remove end cap( i used a screwed driver)

Step 3: Step 2

1. Cut the blue connector at the point where the scissors are placed in the image.
2. sand and file the surfaces that has been cut
3. Cut the bottom part of the blue connector just below the bic logo. Afterwards file and sand it. You will only need the part without the bic logo.
4. hot glue the blue connector bit that can fit inside the pen tube.( push it in so the whole thing is inside the tube. just at one end. The picture next will display what i mean.)

Step 4: Step 3

1. dig a hole into the tube as shown.
2. Start sinking the knife into the pen tube and sliding it forwards to create a long slot.
3. start carving the edges and filing it so it becomes wider. 3 mm wide and length varies on how many springs the pen gun contains.
4. sand edges so it is smooth and remove unneccessary pieces of plastic hanging on the edges.

Step 5: Step 4:

1. Connect the blue connector that was cut earlier, and connect it to the yellow tip.
2. Pull the yellow tip from the inktube.
3. Hot glue it back together so it has a tighter and stickier fit. Remove any dispensable glue.
4. Put the inktube inside the pen tube. On the inktube, just before it reaches the top of the slot that was cut out, create a small hole from a thumb tack or something, a whole where one end of a paperclip can fit in it.
5. Get a paperclip and cut it so its about 4-3 cm. Then, bend it so it is about a right angle side of the right angle smaller than the other.

Step 6: Step 5

1. While having your inktube inside the pen tube, insert your springs.
2. If your springs do not reach higher than the hole u made on the inktube for the paperclip, simply insert the smaller side of the right angled paperclip into the inktube.
If your springs are height is beyond the hole that was made on the inktube, simply take a skewer and push the springs down so its under the hole(compressing the springs)and then insert your paperclip.
3.pull the yellow tip so that the springs fully compress. Mark the point on the pen where the ink tube can not possibly go down any further. Mark that point with a texta or permanent marker. Cut the hole like in the picture below.

Step 7: Homemade Ammo

If you do not possess BB's, you can create something similar by making solder balls or balls out of glue(produced by the hot glue gun).

Step 8: Firing

Pull the paper clip down and twist it to the side hole at the point where the springs are fully compressed. Once done that, flick the paperclip out of the hole and it should fly up shooting anything inside the pen gun.
<p>nice! Very similar to a zip gun </p>
during the knife part i sliced my pinky open but great instructable
That has happened to me before, i was cutting a piece of plastic, i cut my finger, i thought it was a nick but it was a deep cut
<p>That also happened to me while I was cutting popcicle sticks for making the micro x-bow. ouch!</p>
<p>same thing happened to me when i mad my own pen gun. </p><p>(the X-acto stabbed my leg).</p>
<p>That also happened to me while I was cutting popcicle sticks for making the micro x-bow. ouch!</p>
I did the same thing trying to make the bic bow and arrow crossbow.
ouch. i did that with my thumb, but it was cause i accidentaly left it next to my alarm clock so imagine my surprise when i stabbed my thumb! that really woke me up!
smoooooth
Hi,<br>What i did was first i created a slit, then fit a small filer in there just file away the plastic, once the slot is just big enough, id use the knife again to shave the edges.
i'ma having a hard time making the slot wide, any suggestions???
Lol - It says at the top, &quot;Step 3: Step 2&quot; :D<br> Great ible!<br> Win Guy
i just realized, that could double as an auto loader magazine :P<br><br>so you pull down the lever all the way and lock it, fill it up with bb's, attach the top part to a compatible gun's feeder, unlock it, and that way it can auto reload a gun. ofc. such gun would require quite some work to make, but it is possible and it would be quite epic (i guess a type of bolt action could be modified to work with this. all you'd have to do is make sure that where the BB's enter from there is a small &quot;trap&quot; kinda thingi which would stop the BB from sliding right out, and the spring would have to have a cover so that as you pull on the bolt a BB doesn't get stuck in the spring, thats about all, and it should work)
i just cutted it as straight as i could. you could draw a line on what u want to cut with a texta
did you just say cutted?
WOW! I had this ame idea like 2 months back. Well good instructable, its alo t better than the other pen guns.
Except I glued a screw to the inktube instead of an ink tube.
the theory behind this gun is good, but i epic failed and wasted 4 pens because i couldnt get the firing mechanism/charging handle attatched correctly, and the springs slipped out of place all the time. it never actually shot any of my ammo.
&nbsp;omg... the &quot;charge&quot; mech. is simple yet soo cool. awesome. I'm gonna try to make this thing.. best pen gun design ive found...
&nbsp;i love it the instructions where a little confusing you should sat that the blue guard has the writing piece right next 2 it.
i dont get what you are saying :S. <br />
