Step 10: Bottom Assembly

I take the wire lead, coming out of the side of the piezo module, and I thread it through that section of pen body tube with hole drilled in the center (in Step 8). 

Then I attach the end of this wire to the spring, from the clicky-retractable mechanism, of the Inc(r) Classic Gel. 

I don't solder this connection.  The wire is held in place in the one of the ends of the spring, where the springwire is coiled tightly. See picture 1.

Next, in picture 2,  I slide the tip/bottom terminal and its ink-tube section through the spring, and through the section of pen-body tube.

Next I take it all apart, because I take it all apart, because I decided the length of the ink-tube section wasn't quite right.  It looks like I decided on a length of 3+5/16 inch for the total length of ink-tube and brass tip together. See picture 2. 

Next I put it all back together again, and the completed bottom assembly is shown in picture 4.
sir please give me your whatsapp number with country code...Thanks and Regards
I made it! But it's a little bit messy.Thanks for sharing your idea!
<p>Hey, nice work! I'm glad that worked out for you.</p>
Hahahaha, love it. You are a master of words (and technology). <br> <br>&quot;Providing pulsed power when you press the plunger, this pocket-sized plaything is sure to be a pleasing plus to the plurality of pens and pencils presently populating your pocket protector.&quot; <br> <br>This pulsating pen will be quite handy for me so I'll build one. Thanks for the nice instructable.
You're welcome. I'm glad you liked this 'ible, including the unnecessary alliteration in the intro.
Little lightning bolts? If one carried this on a plane, would they be subject to arrest?<br><br>btw, that Evil Knievel stimulator hoopjack thingy really did work to alleviate pain.
You mean the would the <em>person</em> be subject to arrest? It doesn't make much sense to try to arrest the little lightning bolts.&nbsp; So I guess by &quot;they&quot;, you mean the singular hypothetical person carrying the piezo-pen.<br> <br> I am also going to guess the answer to this question is &quot;Yes&quot;, and this hypothetical airline traveler, he or she, could be arrested and charged with some kind of heinous crime, and disappeared into a Kafkaesque secret prison system, never to be seen or heard from again.<br> <br> At least that's the way they do things in my home country, the Former United States.&nbsp; As a general rule for commercial air travel in the FUS, you should not bring with you any item which you prefer not to be: stolen, broken, soiled, irradiated, or touched inappropriately.<br> <br> Because I consider my body to be on that list, I haven't taken a trip by plane in years.<br> <br> BTW, there was a movie released a few years ago titled,<br> &quot;Harold &amp; Kumar Escape from Guantanamo Bay&quot;<br> <a href="http://www.imdb.com/title/tt0481536/">http://www.imdb.com/title/tt0481536/</a><br> which explores this topic (of bringing one's homemade invention on an airplane trip) in greater detail.<br>
LMAO! The trailer was a riot!
