Step 1: Materials
- Empty ball point pen ink cartridge. The one I used has a outer diameter of 3 mm and inner diameter of 2 mm.
- Utility knife
- Anything that has a needle on it.
Step 2: Cut the End
Step 3: Pierce.
If you want to use this tool on a electric drill, cut the tube to appropriate length.
Your $0 wire-wrapping tool is done!
Step 4: Wrap.
Pass the stripped wire (about 1 in long for AWG 24 on 2.54mm spaced pin) through the hole you pierced from inside of the tube to outside. Make sure some of the insulated part is in the tube.
Put the wrapping post (the pin) in the center of the tube. Push the tube/pin all the way in.
Put the drill in forward. Pull the trigger. Or twist the ink tube by hand.
The wire should be wrapped on the pin.
Step 5: Bugs
Another problem is the short life of the tool. After about 20 wrappings, the hole will become a wide crack. But all you have to do is cut off the worn out end and pierce a new hole.
