Great build mate, can’t wait to see the finished product 
Making the momentary switch button & copper retaining rings.
I cut three pieces of copper tube, two from 22mm diameter and one from 10mm diameter & filed flat.
The larger pieces are for the front bezel and switch retaining ring, the smaller for the tail switch button.
Cut & filed round a 20mm disc from FR4 board, marked three slot positions, drilled and filed out with small diamond files.
Removed some copper from the outer disc and a 1mm copper wire circle soldered to the back of the cover with slightly less diameter than the Fr4 board to avoid unintentional contact to the flashlight body.
10mm copper tube piece soldered to front and diffusion film cut out to stick underneath.
Chemically antiqued copper facing, diffusion film disc put in place and UV setting glue applied.
Showing 20mm x 2.5mm copper switch retaining ring. 
Using titanium sheet, I marked & cut out a piece, filed round to 8mm diameter and fixed to the centre of the 10mm x 8mm copper tube with JB weld.
And polished.
Acrylic diffuser disc made to sit on top of LEDs and spring fitted.
.
Since the brass bolt is connected directly to the battery negative it seemed logical to fit a spring here and have a momentary on switch connection.
I also made a temporary brass casing from 25mm x 22mm brass tube and inserted the copper retaining rings, though they are not fixed in place.
.
The outer casing, reflector and LED are still temporary but this gives an idea of the finished form.
Test of momentary tail switch button :THUMBS-UP: 
Still waiting on some parts to arrive but we're getting there :-) :THUMBS-UP:
All that “temporary” stuff and it’s still a functional light 
Yeah, I’m still waiting on the LED, reflector, glass and they sent the wrong tube for the outer shell but I got not patience and need to see it working 
Amazing number of hand made pieces. All nice
Absolutely amazing build with rotary UI. Beyond impressed.
Had to catch up on a whole lot of story, amazing work, so many good ideas, so well exercised, so many patient hours of work.
I’ve no idea how you make such intricate pieces. One day you will make a video. 
I’m beginning to think he has some Elves cutting and filing over there—definitely some Magic Dust—

Now you know his secret
very funny!!!
Jerks! :))
Now a little something for your insolence... ;)
25mm x 22mm grade2 titanium tube arrived today :THUMBS-UP:
I think this is much better than the brass, a lot lighter too.
Drilled & filed out slots for 6mm x 1.5mm tritium vials.
Roughly showing how the light will look with tritium mode indicators
Maaan that’s some great skills and awesome ideas !
I love it !
What did you use to make the slots?
The trits are 6mm x 1.5mm and I only have 2mm or 0.9mm drill bits, (the thought only just occurred to me) so I used the .9mm bits to drill a series of vertical holes in wobbly lines , then kinda drilled in from the sides of the holes at an angle moving the drill bits around to break the holes into one another then a diamond cone shaped dremmel bit to enlarge the slots so I could get the small rectangle diamond file in there, still needs tidied up & nothing is fixed in place.
Very excited though, first light I’ve made with titanium
You can stop making it better now…. anytime now… It’s already really really awesome.
With all the awesome things you’ve made over the years I’m surprised you haven’t played with titanium yet. This first dabble with it is looking very nice already.
Just a couple more tricks, promise :innocent:
Thanks mate, yeah it is surprising also considering it is my favorite metal. I just never got round to it though I think we can expect more of it now
