Introduction: BIC BB Pen Gun Second Edition
Step 1: Materials
Look at the pics.
Step 2: Salvaging Pen Parts
Take apart the clickable pens. You will only need a few of the parts from the clickable pens: 1 black tip, and both springs.
Step 3: Get the Black Tip Ready.
This step will tell you how to prepare the black tip for your pen gun. It's an important part, so do it right.
First, take your drill and 5/32 general purpose bit and enlargen the tip of the black tip by drilling in through the back, like the main pic. Second, you have to file(dremel is easier) down the little edges that stick out around the middle that would keep the tip from going into the pen tubeand file those down, alond with the area that actuall should go into the tube, so that the black tip can be pushed in completely into the tube. Note: Make sure you file or dremel it down enough so it can be pushed in but it should be big enough to keep itself in, in other words, dont let it slide out. you also dont want it to be hard hard to get in. Test for this often while filing or dremeling. The final thing should look like the second picture.
Step 4: Get Normal Pen Ready.
This step will prepare your other pen to be made into the gun. First, pull on the tip of the pen, and the ink should come out. Using the coathanger wire, push out the end cap on the other side of the pen. Throw the little piece you just pushed out of the tube away.too get the ink ready, dribble super glue down the space between the ink tub and the inside of the tip. The pic shows it well.Wait for it to dry completely.
Step 5: Make the Shooting Mechanisem
This step will tell you how to make the shooting mechanism. First, slide the black pen tip point first onto the ink tube of the normal pen. Then, slide both spring on after it. It should look like the main picture. After everything is comfortable in place, cut off the ink tube about a half inch above the top spring. After you have thrown out the little piece, crimp the half inch bare end of the ink tube with the needlenose pliers. Ink will come out the open end, so be ready with a tissue to clean it up. keep it squeezed hard enough to make the tube widen, keeping the springs from coming off the tube. The final thing should look like the third picture.
Step 6: Putting It All Together
This step will tell you how to pull it all together. This step is the trickiest. First, put a tiny ring of superglue aroun the non-pointy end of the black tip on the firing mechanism. Before the glue dries, quickly push the firing mecanism into the front of the pen tube, springs first, pushing by the writing tip. Once it is completely in, pull on the writing tip a bit so it comes out until you see ink cartidge, then hold it there until you think the super glue has dried. You shuld feel the springs resist, if the black tip comes with when you pull on the writing tip, you filed it too much. When the glue has dried, it should look like a normal pen.
