Oh I didnt know the entries deadline has been passed, Thank you OL for the previlege.
I think perhaps there’s slim competition in the machine built category and O-L would like to add some sizzle to the competition. O-L’s call, it’s his game…
Can you tell us more about the tailcap? The transition looks seamless.
Remember those CPU heatsinks with copper stuffed in the core, I always wondered how the hell did the copper get in there. I finally cracked one open using a 5mm Mill Cutter, It was just that simple. No glue, paste, grease anything.(iirc) Just a precision fit.
The tailcap is bored out 0.01mm tighter than the brass insert, This is an interference fit or a press-fit as we know it. But the technical part is to get the measurements “just right” when you’re dealing with only a tenth of a millimeter you just dont have that headroom now do you? Sigh.
It is then hydraulic pressed to a point where the both surfaces are adjoint, facing on a lathe afterwards for the seamless finish.
I had access and some training of machine tools early on.
…I too have something new in my collection, a nice shiny copper EDC! 
Gotta love how the tail cap is done, just gotta!
And it compliments it’s big brother and little cousin quite nicely
With a de-domed XP-G2 at 2.9A, it has a very nice beam profile on this reflector…very nice light!
Not a lot of small lights will throw 100 yds….it’s 97 yds to the red oil drum in the above picture. The light is running an AW IMR18350 cell.
Sweet work Sinner! Absolutely Love It! :bigsmile:
Ah, that little cousin also looks so sweet!
