Today I'll be going over the steps on how to make a Convenient Solder Pen. I find these a lot easier to use than pulling the solder directly from the spool.
Step 1: Parts and Materials
1 Spool of Solder (I used 0.8mm / 0.032")
1 Non Mechanical Pen (Larger pen works well)
1 Pair of Wire Cutters.
Step 2: Disassemble the Pen
Step 3: Coil The Solder
Depending on the type of pen you've selected, you may only be able to coil a certain length. The pen I used could only hold a coil from the top of the pen housing, down to about where the rubber grip begins, anything more wouldn't fit.
After you've coiled a sufficient length of solder, you'll need to remove it from the ink insert. I find that gently rotating/twisting the ink insert as you remove the coil helps it come off easier.
Once you've removed the ink insert, use your wire cutters and remove the solder coil from the spool. Be sure to leave about 1-2 inches of excess on the coil.
Step 4: Insert Solder Coil Into Pen Housing
Step 5: Reassemble Pen
And that's it! When you're soldering, just pull it out from the pen tip when it gets too short. Be sure not to let it get so short that you cannot pull it out, otherwise you may need to disassemble it and uncoil some solder.
