Introduction: Suprisingly Effective Bic Pen Grappling Hook
the title is pretty self explanatory
assembly time: 30 min
Step 1: Supplies
the things you need to do this project are, a simple pen with a barrel and plug, a soldering iron, a low melting point solder, a guitar string, and some twine (at least 10 feet.)
Step 2: Attaching the Plug
For starters take out the ink and writing part, now take a lighter and hold it under the plug of the pen until it catches on fire, after blowing it out quickly push it against something flat and stiff. ir should look the fourth picture on the bottom
Step 3: Inserting the Metal Barbs
now this is where the guitar string comes into play, no pun intended, take a wire cutter and cut off a section of the string. then use the lighter to get it red hot. then quickly put into the barrel of the pen at about a 30 degree angle. it does matter how many you use, but the more the better.
Step 4: Weighting It Down and Putting It on a Line
the next step is putting the solder into the barrel of the pen, so what you do is hold the soldering iron with the solder about 1 and a half to 2 inches above the barrel. Then you slowly let the solder drip off the iron, and into the barrel. Once you have gotten to a point where you feel it weighs enough, you loop another section of the guitar string and pinch it so that it fits down into the barrel. Then you put the solder aroung the string. If it does feel sturdy in there then put a hole in the side, and fill it with solder.
Step 5: Final Assembly
to finish up, just make another loop on the other end of the guitar string, and tie the twine to that. congrats, you have just made a bic pen grappling hook.
