Quick and Easy way to fix Compaq R3000 AC Adapter Power Plug

First of all before I sealed the barrel, I just added a little protection to the connections. I added zip ties on both ends of the soldered section. Reason is, in case someone pulled the cord strongly, then the zip ties will prevent the wires from disconnecting. So with zip ties in place.

Let's get started with the list of materials and tools.
Materials: Generic Compaq R3000 AC Adapter package with different attachments, some zip ties, empty sharpie barrel/ empty highlighter barrel  - if the marker is still working, please don't waste it. just improvise of how you can substitute this part genius! electrical tape.
You might ask why the barrel is necessary. Well it isn't really necessary, but I just think that it adds protection to your soldered wires as you will see on the next steps. Moreover, I think they look more aesthetically pleasing than having a bumpy wire with bunch of electrical tapes wrapped around.
Steps to prepare the barrel
1. Remove the tip of the marker as well as the ink holder part of it.
2. Bore a hole on the other tip of the barrel and we are done with the marker barrel for now.
So now we move on prepping the cords.

1. Cut the cord to desired length. Make sure to leave enough cord length so you could actually solder it to the original laptop cord. As for me, I left a little bit wire on the plug (one that goes to the outlet) side because I might need the Compaq AC Adapter and reuse it in the future.
2. Insert the cord in the barrel.
3. Strip the wires, exposing the wires.
