As the guy who's batteries exploded on him... twice (the second one was scarier and I should post that story today), I am extremely glad to see the vents particularly away from the eyes.

Eskimoroll, Please post both of those stories. I would like to know more about the risks... in real terms. Type Batt, Cause, Effect. Maybe they can be a Sticky under Battery mods. Thanks.

ForcedFuel, that looks great!

The first story is a sticky post within this forum (Modders forum) and the second story (the scarier one) just got posted in the General Forum.

My mother was the inspiration behind this. A two pack a day smoker her entire adult life; I watched her struggle time and again to quit. Several months ago, she discovered the e-cig and it changed her life and she has now been analog free for going on five weeks!

Having loved to fabricate my entire life and watching her deal with poor quality parts that fail in short order, I could not resist putting myself to work creating her a truly unique, beautiful and most importantly functional and dependable e cig with many features not found on most other e cigs. Right now im running a 3.7v CR123 style battery in it and I am thinking of trying a 5/6 volt set up.

Features-

1. Adjustable Air flow (simply turn the set screw to adjust) so that she can adjust the draw to her liking.
2. Completely mechanical, no solder, no electronics.
3. Locking switch, prevents it from turning on when in pocket, simply twist to lock.
4. 3 machined safety vent ports. Though highly unlikely, it allows venting should the battery explode, thus helping to keep the body from fragmenting. Vents are machined at a 30 degree angle to help vent any gases away from the eyes. (i added these after reading the post about batteries exploding...though unlikely, I know the peace of mind is irreplaceable, not to mention your eyesight)
5. All machined aluminum and brass.
6. Billet Machined Button with replaceable contact. Can not fail.
7. Knurled front cap for grip.
8. No rear cap for simplicity.
9. Rear machined grooves for grip.
10. Battery chamber sealed from atomizer, thus no sucking in of any battery gases.

Many of the features I incorporated into this came from the modders forum so I hope you enjoy it and it gives you some new ideas with which to make your own mods!

I'd like to be the first to say what a great son you are to have manufactured that for your Mom! I'm sure she is very proud of you and thanks you tremendously for all of the time and effort you put into that product for her. You should take great pride in a job well done and very well thought through!

My mother is my biggest critic...lol. I think the most amazing thing about the e cig is it is the first product that actually has worked for her. She has tried patches, gum, cold turkey etc and nothing has worked. I am a non smoker so it is pretty exciting to see that e cig's actually work for her, even when she is under stress!

I'm interested in the threading, I'm looking at picking up a metal lathe for this exact reason, how exactly do you set it up to create threads?

You can buy a chucking die holder to hold round dies(i just turned my own) and a collet to hold taps or chuck them, get a chuck 1/2 to 3/4 depending on your tap size and die holder size. I do the small threads on the lathe and big threads with the die in a mill. You'll want a lathe or mill that will turn low rpm and still put out sufficient torque, small lathes just stall out, even on smaller threads (i run it at about 25 rpm)

Lathes can also cut threads, but they(at least non cnc lathes) are not practicle for small inside/outside threads and take a fair about of time to set up for larger outer threads.

I really like how it isn't oversized in length... and the styling is SWEET... where is the button?

VERY well done.

The button is in the end (with the two circles machined in it). The button is solid billet machined aluminum with a replaceable brass contact on the inside. I did this so it was the ultimate in durability, it cannot fail (well unless the device gets heated to 1700F and the aluminum and brass melts). I also machined my own button so it fit the lines and countour of the body and doesn't look like an out of place add on. Store bought micro switches are notorious for failure and i wanted to eliminate that weak link.

I appreciate all the compliments!

I was reading a thread about some concerns and problems some people had with another manufacturer's e cig's going off when setting it down on metal surfaces or contacting other metal things such as coins.

In reading the threads on the devices in question, it appears when a piece of metal bridges the gap between the button and the body, it will turn on the device without pushing the button down, thus leading to overheating and a possible safety hazard. I have found that when the e cig is turned on for extended periods of time(meaning several minutes or more continuously, not intermittently), not only the atomizer overheats leading to atomizer failure, but the batterys also get very hot which could lead to batteries exploding.(I believe most manufactures recommend no more then 160f before risk of explosion) One of the posters in the threads indicated that many of the other e cig designs out there have the same design problem.

Having been posed this same concern about my device by others, I can tell you that my switch design is different and will NOT go on by any metal touching the body and switch simultaneously. You can set it against or on any type of surface, including metal without fear. The only way my device can go on is by pressing the button, which also contains a locking mechanism for when not in use (simply turn the switch 1/2 turn to lock)

Just thought i would pass that info along...
