Nitecore D5 - Piston Drive CR2/14250

Piston drive used to be exotic & so was CR2/14250 lights,not anymore.
However, I've never seen a light that combined the two together. So I figure it'll be cool to make a mini PD ?

Here is the starting material: A brand new Nitecore D10 R2/HA III Gray.


I first filed away the HAII coating at the tail, it's easier to do it with the whole light. Then, I cut the tail section off. It'll be re-jointed with the top half of the body later on. Hopefully, I'll be able to finish it up this weekend, but for now, I only had time to give it enough damage to send it on to the road of no return:

I can't wait to see a final product!

Re: Piston Drive CR2/14250

Some more progress this morning:

I tape up a Jigsaw to "constant on" & use it to cut just out side the pre-marked line:


Grind it up with a mini grinder to where the line is:


Next, I used a Knife Sharpening stone to smooth up the surface under running water:


Then, open the end up with Step drill bit:



Test to make sure the Piston still fits, this is the half way product:
The "Belly Dancer" :devil:


The "belly dancer" is still a "turn on", thanks to the PD mechanism that doesn't need the flashlight body to complete the circuit.



I haven't cut the piston yet, just a sneak preview of what the size of the Mini PD would be. Also need to clean up the cut end a bit more, as I made it 1-2mm longer so I'll have room to clean up the "Cesarean section" wounds.



Stay tuned...

ma_sha1, your stubby mods are great and this is the best one yet!

Re: Piston Drive CR2/14250

Thanks, MWClint, very kind of you.

Now, the piston has been cut: Look how tiny the piston is, so cute


Finally, a bit flashlight "niptuck" & then applied JBweld & clamp them together.
Now comes to the worst part, I must wait 6-12 hours

Re: Piston Drive CR2/14250

The waiting is the worst part..............When will these be availible for the rest of us??????

Re: Piston Drive CR2/14250

Sorry, won't be from me, may be Nitcore could release one at some point?
I don't do custom mod service, only for fun

Re: Piston Drive CR2/14250



I had the misconception this thread is going to ask for available CR2 PD lights in the market. Boy, was I wrong.

Re: Piston Drive CR2/14250

I saw your "Tribute to Nitecore D10", that was excellent thread!

Imagine if they release a line of "Nitecore D5" in all the various anodizing color finishes?

Dude I'd hate to be the bearer of bad news but I think you've voided your warranty! Seriously though. Very nice work there. :thumbsup:

Really? :mecry::mecry::mecry::mecry::mecry:

Nice work!

Thanks!

Finally, the 6 hr wait is over. The finished product is only about 3mm(About 1/8 of an inch) taller the Mini Ti,
but so much more advanced than a twisty. Also, to the right, compares to the the full size camo D10.

Interesting project, very nicely done.

The original spirit of CPF lives on with you..... and you used JBWeld too!!

Ya rule!!! :twothumbs

Thanks for the post, hopefully Nitecore will follow thru with your extensive field research and R&D prototype.

You are too too kind, my friend. Thanks!

This is the coolest mod I have seen in a very long time, well done :thumbsup:

Very slick mod. I thought Nitecore was introducing this from the title.

Looking at your finished product it looks like they did.

Nice job.

That's a really cool mod :thumbsup:. Looks great.
