Wiring Pen: For next gen in DIY prototyping

We came across ELM chaN's website and wondered at how soldering can be an Art.
Source: ELM chaN Website
In hopes to be able to make this possible, we read through the entire tutorial on Wiring Pen & how UEW (polyUrethane Enameled copper Wire) is used.
Looking at this we wanted to make our own Wiring Pen so we started in search of the raw materials:

[1] UEW: We found an easily available source from Mobile repair Shop. On the website we found indication to using the old Relay Coils or any type of solenoid etc. We found this:
In Bharat its available in any Mobile Repair Shop for others they can take it from an old relay. The best part is that you get a bobbin free if you take it out of the Relay.

[2] Syringe Needle & Pen: This is need for planning the exit of the wire in the Wiring Pen. You can get it from any of the medical shops. Also you would need an transparent Pen for use as the body. So here is a picture of what we have collected so far.
[3] Screw: This is needed to fit the Bobbin to the Pen Body.

Now here is how you Assemble the whole thing:
[1] Fix the Nail to the body of the Pen:
[2] Have a Stopper made out of a Plastic container lid to keep the bobbin in place. We have used a Screw on the Other end also. This was made possible by the use of a Metal Stud in the Center as you can see from the above picture.
[3] We added an additional (pulley using a) paper clip insered into the pen at the end of the pen to help the wire be pulled smoothly without damage.
[4] Next carefully insert the wire through the pen body and out on the other side. Then insert it into the Syringe and the Pen Tip. Here we found that initially that the syringe Needle had a big back projection and it could not fit into the pen. So we cut that out and adjusted it to fit in to the Pen's tip. We also inserted a small filler to tighten the Needle.
After Assembly:
[5] Now put every thing together and you have the Wiring Pen Ready !!
Our Wiring Pen is Ready !!
Hope that you liked our build, let us know your comments.
