Introduction: Mechanical Pencil Solder Loader

Picture of Mechanical Pencil Solder Loader

The Mechanical Pencil Solder Loader, just a cooler way to store/load your solder. Using a 0.7mm mechanical pencil and some 0.7mm solder, this little beautiful thing is made......

So, why would I need something like this? Wouldn't directly using solder from it's spool easier?

Well yeah but who knows? If you are someone who does electronic repairs outside, you wouldn't really want to bring a whole spool with you right? It'll be quite heavy and troublesome to hold them outside. But with the

Mechanical Pencil Solder Loader, you can easily store your solder and use them whenever you like!

In my opinion, this solder loader should go well with the USB Rechargeable Soldering Iron: Solderdoodle Pro!

You could bring both of them easily anywhere and use them whenever you like!

Anyways, this is just a strip(or strips) of 0.7mm solder loaded like pencil leads into a 0.7mm mechanical pencil.

Step 1: Preparing the Solder and the Mechanical Pencil.

Picture of Preparing the Solder and the Mechanical Pencil.

Get a 0.7mm mechanical pencil that takes in 0.7mm leads and also a spool of 0.7mm diameter solder.

Then, cut the solder into smaller strips of about 10cm (4 inches). Cut a few so you won't run out of them that soon.

After cutting them into smaller strips straighten them so them can be easily loaded into the mechanical pencil.

Step 2: Load 'em In!

Picture of Load 'em In!

Take your solder 'leads' and load them into the mechanical pencil. After that put the cap back and start pressing to load the solder to the tip.

And now you're ready!

Step 3: Use 'em

To use the solder. Press until a length of solder is loaded out and use them to solder your components.

Step 4: Completed.

So that's the Mechanical Pencil Solder Loader! Thank you for reading this instructable. Have a good day!

I had a ton of mechanical pencil holders of various sizes and diameters left over from engineering school. What a great use for them!

jscalisi (author)2015-08-17

ugh, i got really excited and tried this out, only to find out my solder is .022" diameter. fantastic idea though.

ImagineCircuits (author)2014-12-30

a metal tip would be safer to use than a plastic one

bneo99 (author)ImagineCircuits2014-12-30

Yep! Would be able to prevent from melting the tip. But as for me I do not have any mechanical pencil with metal tips on hand currently.

WJR339007 (author)bneo992014-12-30

maybe you could try using a 0.9mm pencil and put a metal tube that has and outside diameter of 0.9 and an inside diameter of 0.7

nancyjohns (author)WJR3390072015-01-02

0.9mm mechanical pencils are hard to find.

WJR339007 (author)nancyjohns2015-01-02

Just last week I got a pair of 2 really nice ones for about $7 at either Office Max or Office Depot

nancyjohns (author)WJR3390072015-04-25

Oh. Does that mean that the're more common now?

WJR339007 (author)nancyjohns2015-04-25

I guess so, I've found I can put way more pressure on the lead without it breaking because it's so think, so maybe they're more common with artists

Try the Zebra M-701

Godzilla54 (author)2015-03-22

tubes like this get boring time for a upgrade!

magic universe (author)2015-03-18

super idea, thanks for this idea

Millanbar made it! (author)2015-01-30

Note quite the same. But defiantly helps with small scale jobs.

soul1974 (author)2015-01-27

Well done!

Ganesh Selvaraj (author)2015-01-15

Awesome! :D

MaterialBall (author)2014-12-30

You can just buy solder in tubes.

Whiternoise (author)MaterialBall2015-01-06

Those are awful in my experience. At least the cheap ones are (e.g. the Iroda stuff). The solder comes out so tightly wound that it buckles whenever you touch a component.

RayR2 (author)Whiternoise2015-01-07

I use and go through mechanical pencils like crazy. There all I've used, as far as pencils go, for 15 years. I always keep the worn out ones for parts (yeah I'm cheap like that) so this worked out perfectly for my ".9 mm Mechanical Solder dispenser". I filed down the metal tip of the pencil about a 1/32 to get the solder to push through. The solder will not cycle through with the end spool to tight, but the solder is there easy enough. I may cut the pencil and see about a bigger spool compartment. Thanks for the great idea. This will be handy.

RayR2 (author)MaterialBall2015-01-07

That tube doesn't have an automatic push button feed does it? I thought not. Mechanical Pencil - 1

Tube Solder - 0

In my opinion, it can sometimes be more fun to make things yourself rather than buying a premade solution.

bneo99 (author)MaterialBall2014-12-30

Of course you can do that but with this you don't really need to pull the solder out of the tube...... You just load them in and use them.....

MaterialBall (author)bneo992014-12-30

True that, you only need one hand for dispensing it. Maybe you can find a method with an open back, so you can feed a continuous roll of solder in the back of the pencil.

bneo99 (author)MaterialBall2014-12-31

I think by using a mechanical pencil with side click it is possible. I can leave the back open so I can directly take solder from the spool. I plan to look for a mechanical pencil with metal tip and side click. I'll post some follow up pictures if I can find them.

RayR2 made it! (author)2015-01-07

Freaking Brilliant!!! I just made one and its the best for tiny solder jobs! Thank you so much! Awesome idea! I did mine with a Paper-mate .9 mm mechanical pencil and left the solder coil at the back. I'm going to loosely re-spool the solder and put it in the back of the pencil. I gotta say it again....AWESOME! Thanks

Christech28 (author)2015-01-07

Brilliant!!!! Hmm... now what else can I fit into a mechanical pencil...

jwhitten (author)2015-01-07

Cool idea!

hnakkabuff (author)2015-01-06

Wouldn't it be better to use a side button pencil than the top button pencil? That would allow you to have a loading cap open and just feed straight from the roll through the pencil.

ibwebb (author)hnakkabuff2015-01-06

lol I was thinking the same thing and on my way to ask if he had thought about that. Though I know he mentions having a small amount to take for outside jobs.

bneo99 (author)ibwebb2015-01-06

I've thought about using mechanical pencils with side clicks but as of now I do not have one with me... So i just used what I have which is this one...... Once I find a good side click pencil with METAL TIPS I'll post a follow up picture or something.....

CandyMUFF (author)2015-01-06

such a genius idea!! Thanks for sharing the knowledge :D

grey_starr made it! (author)2015-01-06

I like this - I design hearing aids at Unitron - lots of soldering happens... so I gave this a try... now I am trying a mod with a side load slot that can have continuous feed from the roll :)

grey_starr (author)grey_starr2015-01-06

The continues feed works - just need to be aware that the core on a standard mechanical pencil can spin... but hey - awesome! There was a hole already in the core that I made just a little bigger for easier installation of the solder. I could see it through the body of the pencil - so I marked off the top, pressed and marked the bottom before randomly cutting.

grey_starr (author)grey_starr2015-01-06

Check out that HUGE pcb!

achang1 (author)2015-01-06


bluEYEdea (author)2015-01-06

Genius! Makes me want to take it one step further... Auto spool feeder like a mig welder.

SFNativeguy (author)2015-01-06

Friggin' genius. I've been a tech for almost 20 years and this never occurred to me.

Carry on!

RonB2 (author)2015-01-06

Clever idea and it might even help keep me from burning my hands.


absolutekold (author)2015-01-06

I must say this is sexy. I used to use a hollowed out pen with a solder coil made by wrapping solder around a small dowel such that the coil fit in the pen body. You still had to pull the solder by hand but it did the trick to making it portable. Now someone needs to get a mechanical pencil with a side click (I know pentel makes one) and 3d printing something that would hold a small spool and provide a feed for a bench top "high use" model.

bneo99 (author)absolutekold2015-01-06

Yep, side click mechanical pencil, I've thought of using bobbin from sewing machines... they are quite small and can be easily found... maybe some simple trick would hold them together. But if we were to have it look cool then we can 3D print something to hold the bobbin.

RodrigoP2 (author)2015-01-06

This is pretty cool. I'll try it.

pointedspider (author)2015-01-06

I usually wrap a few wounds around a pen. This is cool tho!

Daltsy666 (author)2015-01-06

I like this idea. A LOT.

wbsbadboy (author)2015-01-06

Now this is an idea that I intend to use! THANK YOU!!

sipek (author)2015-01-05

its really smart. I was using needles with mechaincal pencils but this is also a great way to useit. But im not sure if my solder tin is that thin

bneo99 (author)sipek2015-01-05

I used 0.7mm diameter solder on a mechanical pencil that takes in 0.7mm diameter pencil leads. You can even go down to 0.5mm if you have solder of that diameer

keithdbrinkman (author)2015-01-05

is it hard to find the solder? is it silver solder?

bneo99 (author)keithdbrinkman2015-01-05

Nope, it's just normal 60/40 leaded solder

Viskestykket (author)2015-01-05

Brilliant! :D

sghosh21 (author)2015-01-03

Thats genius dude !!!!!

Babybg (author)2015-01-02

Looks cool I like all the pens and the paper and all that ... And even I am a girl I Love Lego it's awesome (even thought it is noting to do with you thingy that's awesome)
