Turn an ordinary clicking pen into a solder dispenser, a bit of solder comes out with every click. This takes advantage of the pen's mechanism which actually spins. You can still use the pen as a pen.

Inspired by the simpler (and in a way, better) pen dispenser in the Guide to Field Soldering instructable.

Step 1: Parts and Tools

-a clicking pen
-a tooth pick
-small length of wood, 4mm x 4mm x 1" long is sufficient
-hot glue gun
-drill with a 3/8" bit
alternatively, it might be worth trying something similar with the mechanical pencils in which you twist near the tip to advance the led. inside, there's a coil of wire and the led is pushed through sort of an archimede's screw principle. the led might be replaced with solder. if it worked, it'd be much simpler.
And it would hold much less solder if the solder was straight instead of coiled.* Also, that mechanism's called a leadscrew (pronounced as in 'leadership', not as in 'pencil lead').<br> <br> *Thinking about this again, I thought of a way a leadscrew pencil might be good for this:<br> 1. Detach the knob from the leadscrew and attach it to a rod that runs down the center of the pencil (where the lead was).<br> 2. Coil the solder around the rod.<br> 3. Connect the solder to the rod so that it can slide along, but not turn around the rod. (A slot in the rod might work.)<br> 4. Turn the knob.<br> It might be a bit less convenient to turn the knob than to press the button on top of a clicky pen/mechanical pencil.
I've seen those. They use really long pieces of lead, so solder long enough might bend instead of coming out the tip.
every click will give you about 2mm solder. nice idea, but it needs to be improved.
yea it doesn't retract sometimes, loading is a pain, the wood is ugly, and i was trying to go for a "mechanical solder pencil" thing before this. and yes i know it is extremely unpractical, in fact i will never use it does anybody have a good concept for a home made "mig soldering iron"?
how about get a cheap $8 cassette player, and a tape, take out the magnetic strip, put a rubber washer around the rim of the spool and an idling roller with another smaller rubber washer of the same thickness as the washer on the spool, placed so that the spool will drive the free roller, coil your solder around the un-modified spool, then drill a hole through the tape directed to the point where the rollers meet, and put a piece of tube into the hole so that it nearly touches the rollers on the output side, thread the solder through this tube onto a flexy tube of plastic or rubber which is linked up to a block of refractory material with a hole drilled through it at like a 45 degree angle to the tip of the soldering iron, and another hole for the soldering iron itself to go through., and onto this refractory material of your choice (dont use metal, it will act as an unnecessary heatsink and slow the heating process up) put on a handle with the &quot;play&quot; electrical contact linked up to it as the trigger. then you'd just turn on your soldering iron and then hold the contact down when you need more solder on the tip of your iron. <br> <br>i know this is an oldish instructable so you've probably found your own solutions but i just found it and thought i'd share.
Oldish is an understatement, this was 4 years ago when I was still in high school<br><br>This Instructable is embarrassing compared to my recent projects<br><br>Anyways, your comment itself deserves to be its own Instructable!
Yeah i figured you'd be right up there by now, i was wondering what sort of original(ish) hack i could do as an instructable, and that question gave me the inspiration i needed. I think i just needed defined parameters to problem-solve in, which i thank you for. I've started some cad drawings for the hand-piece bit which i'll mill on my CNC'ed hq-400 chinese import. It might go on the back-burner for a bit, my temp job ended a fortnight ago and i've got to find another one, kinda stressful as i dont have any qualifications (self-taught dropout). Tonight i will probably be casting some Al ingots for milling out of some 20 ft long 50mm core diameter cable with split sheathing i found dumped near the wharf a couple months ago. <br> <br>i'll post it up at some point though.

I just lost mine so I can't give you a photo of that in the battlefield, but as long I buy one I'll send a pic for you to see...
you could have a small motor turn two small wheels so that the solder will be pushed through it.
like a welder...haha
Yes but everything involving soldering is ugly until you see your contraption work ; ) Suddenly the wood doesn't seem so bad
is that yellow and blue solder????!?? :-?
read the instructable he says he got no solder so hes using wire that looks like it
lol i ushally just skim the pics :-P and if i like it i will read it hah! :-D
oo and if that was real solder i would by it a lot of it lol :D
What do you mean? You would travel by it? You would do things by it? Or perhaps you men you would "buy" a lot of it.
what is this phrase "you men you would"? what does it mean to "men" something? lol
Great idea dude I tested it and it work like a charm!<br/><br/>Kepp the good work coming! <sup></sup><br/>
i got a 1lb solder roll from marsh in wi
hey greaaat idea
Hey nice instructable hmmmmm u should have a look at my pen and try and combine we could a have a super pen!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1 search my name if u wann ahvae a look. cheers Nato
That is Sooo Cool!
i know i think its pretty cool
Okay, someone needs to figure out how to get the solder through the pen tip...
