How to Make a Solder Pen




Hello All.

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

You will only need 2 different materials and 1 tool for this project:

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

Take the pen you've chosen and completely disassemble it. Do not throw away any of the components.

Step 3: Coil the Solder

Take the Ink Insert from the pen. Begin coiling the solder around the insert.

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

Straighten out the excess solder you left on the coil and begin to fit it into the housing of the pen.

Step 5: Reassemble Pen

After you've inserted teh solder coil, reassemble your 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.

Step 6: Other Thoughts

You may want to create spare solder coils refills for convenient reloading. A good idea is to take the ink insert, make some marks on it showing how long the solder coil should be and keep it with the refills you create.

I made it! I used my drill and BBQ stick (or how it is named) to make more coils.

I have tried the .7 mm pencil and it seems to work but I will have to use it for a while longer to be sure.

What I did to solve the quantity issue was to cut several pieces 2.5 inches long (63.5 mm) the same as the lead length and straighten them. When one gets too short I pull it out and the next one feeds right in.

I wish I had one of my older pencils that has a metal tip but if I keep plenty of length sticking out it hasn't been an issue thus far.

Do not throw anything away. Also, do not use a cheap pen where the nib is molded to the tip. Then, do not spill blue ink all over yourself when taking the nib out. After that, do not run to the bathroom with blue ink on everything you own to try to rinse it off before it sets. And don't let your parents see the blue ink stains you made on the bathroom counter top while trying to wash everything off.

creative, could it work on a mechanical pencil?

Would it work if you got a mechanical pencil, and got solder the same size as the led, the use it like it was a pencil?

I use 0.7mm solder, and if you straighten it out pretty well, it goes through a mechanical pencil of the same size just fine.

I think you will have a hard time finding a mechanical pencil that uses that big lead.

There are mechanical pencils that use 1mm lead which should work just fine. Now, I'm off to staples.
