Piezo Pen Pulsed Power Source

Step 9: Brass tip/bottom terminal

This step shows how to make the tip terminal.  This part will go into the bottom of the pen.

The brass tip itself is the tip removed from the Papermate(r) Eagle(r) in Step 6.  As found,  it is not exactly the shape I want it to be.  It is shaped like an arrowhead, and it just a little too wide to fit through the hole in the end of the Inc(r) Classic Gel (r) body.  So I chuck this brass tip into my drill press, and grind it down a little bit, so that its shape resembles  a "bullet" more so than an "arrowhead".  This is shown in pics 1-3.

Next I solder a piece of solid 24 AWG copper wire into the end of this brass tip, and I thread the wire through that piece of ink-tube, and stuff the tip into the end of the piece of ink tube.  Last, I bend the wire over, and trim it off.  This is shown in pics 4-7.
