A truly amazing job, CRX. Fabulous result.

My simple build just crashed and burned this evening…

O well…

CRX · 2018-11-22T22:51:34.000Z

Thanks mate. Sorry to hear that, it’s happened to me many times too but always a learning experience, even if at the most awkward of times.

djozz · 2018-11-22T23:07:52.000Z

That is a fantastic result!
It is hard to believe that that supernice flashlight in the gif above is completely built with hand tools! Only when you see the complete build thread you realise that.

CRX · 2018-11-22T23:10:55.000Z

Thanks djozz, yeah if you look close you can even see the hand tools latest inprint on my left thumb (hacksaw)

CRX your builds are always amazing but I think this one take it to a new level. I admire your creativity, skill, and especially your patience.

CRX · 2018-11-27T17:04:02.000Z

Thanks very much, sure was a lot of patience went into this one O:)

Diffuser/ protective case.

I made a simple diffuser from an old berocca tube.

Rubbed down with wire wool to remove the printscreen, cut some from the length of the tube, installed a ring of stickyback felt inside the tube for a snug fit and added some GITD powder & UV glue to the ends.

Can also be used as a protective case for the light.

This light is so marvelous both in appearance and technique!

CRX Rotary - Complete.Specifications:

Copper & Titanium construction
Cree XP-L HD v6 3D emitter
GITD O-ring & LED surround
20mm Copper DTP MCPCB
19mm x 8mm solid copper heatsink
20mm x 12mm SMO Reflector
22mm x 2mm dual coated ARC glass
Lighted Rotary six mode tail switch & Momentary button
Dual colour Tritium indicators
Lockout-able
Diffuser/ protective carry case
Magnetic cell contacts
18350 cell compatible
Removable USB charging unit

Length – 94mm
Width – 25mm
Weight – 180g (With 18350 cell)
Parts Made - 80 (Approx)
Time to build - 101 hours

Modes, Operation & Light output:

Pressing the momentary button or turning the rotary tail switch clockwise gives these approximate outputs:

Mo Switch - 1560 lm
Mode - 1 - 1500 lm
Mode - 2 - 450 lm
Mode - 3 - 180 lm
Mode - 4 - 45 lm
Mode - 5 - 3 lm
Mode - 6 - FF lm

Max cd - 9000
Max Throw - 190m

.

The rotary tail switch can be operated through 360° in either direction starting in the highest or lowest mode.
The use of a lubricated o-ring underneath gives just enough friction for smooth operation.
The tail push button gives momentary access to the highest mode.
The tritium markers give an indication as to switch position/ charging mode.

When the two green tritium vials are lined up on the outer shell , the light is in the off position.
When the green indicator on the rotary tail section is turned to line up with the red indicator in the body section , the light is in direct drive mode, or in charging mode if the head section is then disconnected and the USB charger port is exposed.

Other than that the tritium indicators let me know where the switch is positioned.

MRsDNF · 2018-11-23T20:20:11.000Z

Wow! Unbelievably beautiful! Need to have this one Mass Produced!

toddcshoe · 2018-11-24T07:03:19.000Z

In less than a month you can make this masterpiece of illumination and we don’t have a FW3A yet. Amazing.

I love it, very classy yet practical. Hard to succeed at both. You are a talented man my friend. Great job. Congrats.

I say congrats because the win I think is in the bag.

CRX · 2018-11-24T10:37:14.000Z

I am considering making a piston drive light at some point, which may or may not be completed before the FW3A

Dutcheee · 2018-11-24T11:28:01.000Z

Once again an impressive light CRX. You keep improving your builds :+1:

Piston rod light sounds nice. I have a piston in use as an ashtray, looks nice too. And not so complicated to make

I saw what you’ve done there :smiling_imp:

BTW, and regarding to you flashlight, I like the “diffuser” option “Recycling” materials is surely a neat way to improve the work already done :+1:
