I wanted a Cool SS CR2 light but don't want to pay $$ & get what everyone else get, such as SS Raw or similar.

So I decided to convert one of mine Stainless Ultrafire C3 into CR2.
Here is the before & after shot. Just finished cutting,
have not finished putting the guts back-in yet.

Not sure if the C3 can run on Li-ion or not, if not,
I'll need to swap the chip. Probably put one of my Cree XPG (on pre-order from Cutter) in there & drive @ 1A to get >300 lumens out of it.

It'll be run on AW 14250, same battery as in Raw.
The length after the mod is about 62mm.

Sorry for my poor photographic skills.
Will try to take better photo when all done.

Oh nice one, I like CR2s.

Can you show us a pic of the bits apart to understand how it goes together?

You know some people would pay good money for one of those......
 
Thanks for the good comments, guys.


The concepts is simple, I'll try to explain, don't need a picture really.


1. Cut the Middle section of SS battery Tube (That's the hard part, I don't think you can use pipe cutter as those I had only works on softer materials such as Alu & copper).

2. Make sure the remaining section that screws to the head is short enough, so that that it slide into the tail cap & nearly disappears.

3. The tail cap will meet with the front taper section of the battery tube & appears to be seamless like what you see in the photo.

4.. Then, you JB weld the Tail Cap to the battery tube.

That's it!

The whole thing will only un-screw apart at the head, it becomes a tiny SS CR2 twisty.
It'll still retain all 5 modes, by quickly twist on & off. It does have memory to remember the last mod & turn on to it.

When I am all done, I'll post more pictures. I am still tinkering on how to close-up the big hole in the tail end where the clicky use to be, perhaps add finishing touch with "Gator butt"? LOL. I have some nice Gator skins, which I think will add a classy touch & enhance sexyness of this tiny SS creation.

stay toned.

Made some small progress Today.

I plugged the tail cap hole with a trimmed a penny,
then soldered a small spring to the inside.

Still decided on how to seal the hole from out side. I have 3 options:

A. Seal the out side with a piece of clear plastic, so one can the penny.
B. Do A but cover up with a round piece of Alligator skin.
C. Do A but cover up with a round piece of carbon fiber.

What do you guys think? Which one make the most sense?

Man! That looks awesome! Great idea. I think the little carbon fiber disc at the end would look best. +2 on the request for pictures of it disassembled. I'm going to order another C-3 and try this I think!
 
Nice Mod!!!

I think instead of any of those, get gome GITD powder and epoxy the bottom. That could be nice too.

OK, here is the picture disassembled.

Next to it, is the Carbon Fiber disc version of the tail.
It looks much better in person. The flash is kind messing up the picture.

ma sha 1: Thanks for the pic. That makes it much clearer. The carbon fiber looks awesome!
 
That looks really cool!

I may have to try that myself. I'm curious as to how the stock electronics will handle the extra voltage.
 
definitely a cool mod!


Thanks!


Boy, I haven't finish this yet, I already got a cooler mod coming :D
Check out what I just received, another stainless host but it's AAA.

The plan is to Split one average looking SS flashlight into two super cool mini flashlights!

Steps:

  1. Cut the Stainless AAA host into 2 Pieces.
  2. Mod each piece separately to get TWO stainless steel flashlights out of it!
  3. The longer piece (with original head) will run on 10280 or N cell ~60mm long. About the same height as the CR2 one but slim!.
  4. The shorter piece will Run on 10180, XPG-R4, only 28mm long! It'll be the smallest Li-ion flashlight ever, Smaller than Wee (34mm) & Drake (33mm). Close to the size of La Petite Killer (24 mm) but will blow it out of the water!
  5. The Stainless Clip will be modified & go on to the CR2 light for Pocket EDC.
Absolutely nothing will be wasted, check out the host on the right:

Just received AW leather holster for CR2 Flashlight,
I think it fit in there quite well, my new CR2 EDC.:thumbsup:

No changes needed, it's DX SKU 26122, it runs on 14500 Li-ion,
so 14250 Li-ion conversion is no problem.

Just finished Converting the Stainless A2 AAA to N cell light,
this one can't run on Li-ion, so I am running on NiMN N-Cell.
