hahahahahaha!! thats crazy man, i love it
wow, they`re some serious lenses
Isn't the slot running the wrong way? Surely it would be better in a vertical direction
Sweet Chris, it seems you have achieved what Emu's avatar and my bike stand would look like from the front. Almost erotic art, some see eyes and a mouth, i see something else
Have you played to work out the best distance from the LED to mount the aspheric or is that going to be part of the experiment
You've got to be kiddin' me
Troutie have you tried putting some diffuser material over a bit of the aspheric to provide some flood?
I found 15mm from the surface that the led sits on gives you a perfect pencil beam..but way to tight for anything but a dive light.. I'd guess at the beam being about 4 degrees.
I'd say 10-12mm from the surface that the led sits on to the bottom of the aspherics should be good for a helmet light..
How about making it adjustable via a thread on the front bezel. Tight beam for fast downhills and flood beam for technical ascents, all by a simple 1/2 to full turn twist?
My new favorite light design.

I have played about with one but nothing definite yet as to focus and they may each get a different focus to overlap the beams a little .
Yes Brad I did think about nipping the waist in a tad
the on the fly adjustable is beyond my abilities and attention span .
Jay I am approx 10 mm above the led dome at the moment so can take them down a bit at a time if needed
I see bottle bottom glasses I can't remember the name of the show (Coronation St? <shudder>) but there was a guy on TV with glasses like that..

Have you been having lessons on how to machine things?

All you need is a front cover now..
Chris which bolts are you using to hold the leds down? M2 x 6mm button heads? if so how high do the heads sit?

Lathe and Mill abuse to be sure.
the pics dont show the mistakes made like holes that went too deep or in the wrong place .
Forgot to take photos during the lengthy machining / butchering .
need to make a top with the switch in
wont be a front cover asphericals will be glued in with the infamous serious glue .
when I fine tune the beam at the moment I seem to have a perfect die projected so may be a bit too narrow just waiting for some glue to set before wiring it to the h6flex ..
what I may try is leave one as it is and only defocus the other so the Xpgs will handle the near ground and one for the mid the other max distance .
After spending 2 days butchering this piece of ali I wont be doing another one in a hurry .
seeing as there are no pics this is a brief rundown of opps.
after a good workout hacksawing a 90 mm length of 50 mm square bar off
and then realising I had no way to fix it to my tiny rotary table so machine abuse no one
Fit it in the 4 jaw chuck in the lathe to machine the 2 big holes this was fun and I had to do it on a slow speed as the bit was so inbalanced I did not want to shake the old girl to death this was repeated for the other hole .
Then into the mill for a bit of work designing on the fly with repeated plan changes as this progressed.
space suddenly looked very tight to fit in the H6Flex I was just going to mill a square hole but that would have cut into the led cavity so the only option was to go round .
Que some more Lathe abuse as it just fit in the 4 jaw for some more shake rattle and make swarfe.
With all the cavities now done it was still a chunky lump so it needed a diet I was goint to go mega minimal but reminded myself that my helmet was not aluminium like the bars so no good heatsinking to be had there .
next came some mill abuse with a 4 mm round nosed mill to try and make fins this took the most time today as round nosed mills dont cut just as well as flat ones .
when I had reached the deepest I could go with the mills I foolishley thought to save some more weight I would drill holes through the bits I could not get the mill to reach this went not too bad until 99 % of the way through the first hole the 4 mm drill bit snapped .
Bugger took me an hour to get the bit out of the hole
Repeat for another 3 times and I now have 4 broken 4 mm drillbits and 2 unfinished holes .
Wont do that again .
Thats about it up to the state it is in in the pics .
Jay The bolts I used for the stars are M3 button heads and they stand proud of the star by 1.75 mm
Hats of to you Chris, I think it looks really good

As for snapping drill bits, I always seem to snap the black ones from homebase they are crap. Mrs putt a load in my xmas stocking instead of socks
The Gold jobber bits are pretty tuff, I got a load of 2mm and they have lasted well..
Wow Chris, that is a great little light. Love the way the hound has a ghost walking with it, spooooky.
Well done Troutie, very nice design.
I do my pockets just the same way in the four jaw chuck. Try putting a brass counter weight between light body and one of the jaws to stop the vibration. It works great.
Got a name for it yet?

no name as yet but got to say thanks to you for the lenses
do you have any still in stock as there will be a MK 2 version and also a bar one in the future .plus my riding mates are gonna hate me as I can now annoy them from further back.
YetiBetty. good idea but I was on the last bit of thread on the jaws
Chris, that looks fantastic, well done.
As for a name, what about "Elle" as in " The Body"?
On my smart phone so can't link in what, sorry, who I am referring to but if you Google those 2 names I'm sure you'll find a suitable pic that will explain.
Very nice looking light. How heavy is it?

check out Ahortons headlight here
which I have got to admit did spark the idea for this light ( I hope you dont mind Ash )
been doing a bit of measuring and the top of the led dome is about 9 mm from the bottom of the lense so wondering if it should go nearer
Stu not too sure it has any erotic looks now
something like this should work for your videoing escapades
