CRX Rotary - 6th Annual BLF/ Old Lumens Contest Winner

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!

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

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.

beautiful work!

Such a refined and precise bit of craftsmanship there CRX
I take my hat off to you

I’m starting to believe that you are not human CRX. Is there something your not telling us? Should we be afraid? :sunglasses:

Thanks chaps :beer:

Course not, I like you guys :innocent:

Soo stay on your good side. Okay got it :wink:

Now that you have the protective case you must be ready to send it to me :smiley:

I agree with Moose, your skills are not normal :exclamation:

Wow! Unbelievably beautiful! :beer: Need to have this one Mass Produced! :heart_eyes: :+1:

Cheers David

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

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.

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

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

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

I saw what you’ve done there :smiling_imp:

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

So Berrocas are the secret to your talents. :+1:

Just had time to catch up reading through the finished build - Outstanding build, & really well doccumented. Hats off :face_with_monocle:

Do you have anny Beroccas left? :beer:

I am astonished, astounded, awestruck, bowled over, etc.

When I see the title of this thread I keep thinking your crx has a bridgeport rx-7 mazda motor

Awesome build as always!!
