Introduction: Two Way Ball Point Pen!
We'll be making here a pen that works like a regular pen but has two ball points.
Step 1: Supplies
- wire cutters
- two pens (try to find pens with a straight barrel, any other kind simply wont work)
- an ink reservoir
- some paper
Step 2: Disassembling and Sorting
Take the two pens apart. Make sure that you have all the parts like on the picture.
Then sort the necessary parts form spare parts as shown on the picture.
Step 3: Bottom to Top
Now take one bottom cap and push it into the top part of the barrel.
If you have the right kind of pen this should go fairly easy in the start but become tough (because there is not enough room there).
In the end the top part of the barrel will snap to make room for that bottom cap.
To prevent this from happening you can sand down the groves on the bottom cap and possibly sand down the inside of the top of the barrel too.
Step 4: Assembling
So take the parts that we need and assemble one pen.
Step 5: Cutting to Required Length
Now take that spare reservoir and cut it like on the picture.
Step 6: The Bridge
Now use something to put into the part of the mechanism that is being pressed.
Why? Well, you would want to block that part so when u press the top of the pen the mechanism will still work.
If this doesnt work well (it didnt work for me), you can always do the thing that i did here .
Step 7: Assemble Top Part
Here is how i solved the problem in the previous step.
I modified one part of the other pens mechanism (spare part). I sanded down the edges so it could fit into the bottom cap.
Step 8: Finished
So there you have it.
In the end, if your barrel snapped, you can use some glue to glue together the bottom cap to the top of the barrel.
We have a be nice policy.
Please be positive and constructive.
