This is how I build my DIY genisis atomizers. It makes for easy disassembly for cleaning, inspection, and repairs...
1. Tools: Dremel, small pipe cutter, soldering iron, round file, cutters, pliers, 1mm and 2.5mm drill bits
2. Supplies:
a. Shell
GotVapes 2-Piece eGo Cone w/ Screw-on Cap - PEN-CLIP STYLE BLACK [gv-egoVERTICALCONE-penclipBLACK] - $7.50 : GotVapes.com, E-cigarette Supplies - Atomizers Cartomizers Mods Juice and more
b. Spacer for 510 connection (Ace hardware is where I get mine)
Amazon.com: 100 Nylon Spacer Bushings .257 I.D. 1/2 O.D. Length 5/8: Automotive
c. Tank (I buy these local for 59cents and use the case, not the syringe)
LeCig Electronic Cigarette Store - 3ml Monoject Syringe
d. CE2 or clearomizer of some sort - for the mouthpiece and the 510 connection
e. 18 gauge Silver Wire for the electrodes (I buy local - it is expensive) -
.999 Fine Silver 18 Gauge Round Dead Soft Wire has it in 1 foot sections, you need 6".
f. Clear tube for + electrode insulation in tank.
2mm Clear Jewelry Tube and Connectors
e. Lead free silver solder
5. Threading from eGo/Riva cones (this is used in the top piece)
6. Tip from a DSE701 cartridge. or an eGo Type B drip tip.

Assembly:
1. Remove all the threading pieces from the shell. I use an old eGo batt connection to do this and the eGo cone. Pull threads from eGo cone also, I use this for the TOP. (2 of them if using the 701 tip).
2. Use pipe cutter to cut shell to desired length. Use a socket inside of the shell to prevent crushing.
3. Cut top/airchamber to desired length. Use scrawl to start and drill 1mm air hole (about 2/3 way up).
4. File nylon standoff with a round file to accept 510 connection.
5. Pull center piece out off 510 connection, solder 3" 18gauge silver wire into center on tank side, fill hole with solder.
6. Solder another 3" piece silver to outer of connection on tank side.
7. Slip center conductor into the 510 and seat it. (pay attention to the silicon insulator!!!)
8. Slide and press (a touch of epoxy to hold it) the 510 connection into standoff. (The CE2 connector has an o-ring NO LEaks!)
9. Syringe shell. Cut to length to match length of tank shell.
10. CE2 mouthpiece. Drill 2 1mm holes for electrodes. Enlarge center hole (2mm).
11. place insulator around + (center) wire. Bend wires near connection to allow space for the wick.
12. Slide standoff/510 connection into base (large hole) of syringe case / tank.
13. Slide Ce2 mouthpiece down over electrodes. Seat into tank.
14. Slide (the clear stuff shell steel shell - I remove it to make room for my new tank) your made tank down into the shell. The crimp from cutting it will seat/stop it.
15. Use your top piece to seat the threading into the tank seating the tank. Align the air hole perpendicular to electrodes.
16. Trim electrodes and bend to allow them to hold kanthal properly.
Next post... Set it up and Vape it...
ETA: DO NOT USE COPPER electrodes... You will regret it later for more then one reason!
I really am sorry about pic size. I don't use an outside photo storage, and I can't upload decent photo's here...
