Great build!
I am really curious about end result. I think you could have been bought a 6V bigger MCPCB and mod it to 12V. Not a big deal. Just two cuts with a dremel and a thick wire.
Sorry about the loss of pictures here, I will attempt to replace them.
.
Also, I have finished the parts that were missing and plan to start finishing the light the day after Xmas.
This build became more than I was able to handle and was delayed for lack of experience.
Of course the intent has never changed and that was to eventually put a CBT90, SBT90,
or some hot led in it, keep it cool, and determine how much water cooling is required.
Afterwards a new design can be incorporated that will have a normal appearance.
This light is for testing, not looks, so I will not be offended by comments.
.
Do you have more info about the cooling of the LED/shelf?
If you can reduce the heat of the shelf drastically you dont need all that aluminium wound up next to the head, if you could just take out the heat below the LED.
Or is that your heat exchanger?
.
The MCPCB is .062 thick and will be inset into the copper cooler. The copper cooler is .100 thick it will sit on.
Im guessing this is the shelf you are asking about. As far as technical info on cooling capacity, no I am no Engineer. Sorry.
.
Yes , you are correct, in after thought and already in deep, it is overkill.
The aluminum coil is the radiator and the copper cooler is the heat exchanger.
They will be connected and water will be pumped / circulated thru both.
Here is the battery holder extension to 12v and 8 batteries.

Absolutely love this build. Fantastic so far and thank You for sharing!
Awesome build, i have never seen a build like this. Also beautiful machined parts, i love it!
I wish i had the ability to build something like that
interested to see the performance when its ready!
Do you need a reservoir to prime the tubes? How you are going to prevent cavitation or air in the system?
I want it . I will catch a lot of fish with it
Picture quality is not so nice, lots of noise
they are pretty big with 2.5MB each, you can get that to 500KB without loosing quality through Adobe Lightroom or similar software to improve image then resize/compress

Thanks djmcconn, we lived near Greensboro for 2 years back in the 90’s, loved it there. :+1:
.
Yes that is a concern we will tackle at assembly. I may need to modify the pump for lower output
and use a rubber tank ( small ) to maintain light pressure. Lots of unforeseen problems that I will need your help with.
.
OK, thanks, I thought they were resized when copied but I did not verify it, sorry I will fix that and go back to the camera.
Amazing work Mr CNC. I could look at your work all day. Mesmerising stuff. 
Nice job, keep it coming CNCman. Awesome detailed pics.
Thanks for sharing .

Thank You MRsDNF … :+1:
I will pm you some pics of off topic jobs…
Not convinced its quite as bad as that, I have an L2 setup with a culnm1.tg & 5a driver, I also have exactly the same combo in an aspheric setup
The L2 is making 18Klux at 5 meters , the aspheric is making 24klux at 5 meters……
Lens diameter and FL is a huge factor.
Inspiring!
Like “how to do this with only simple tools” inspiring (for someone without a CNC workshop).
I thought this was most people’s experience too, that a aspheric will outthrow a same diameter reflector, even without a wavien collar.
But seeing the machinery CNC man has in his shop, he might want to try to make wavien collars himself, out of aluminium billet or stock.
When you polish it as good as possible it’ll probably work 80% as good as the real thing.
Well, when they show a wavien collar doubling output they tend to use a worst case example (a small lens with a very long focal length) this obviously shows the biggest gain from a collar being added. but in reality with a sensible lens setup the gain will be far less impressive.
Here is an example
You can see there he has picked a lens with a monstrous 100mm+ FL to make the effect as dramatic as possible.
I am getting 600Kcd out of a 67mm lens with a 25mm FL no collar, I cannot get close to that with an L2/L6 size reflector
I have also had the same result with a C8 size host one reflector one aspheric even with the reflector version cranked to 5 amps and the aspheric only at 3.5a it still produced 70kcd more
I think if CNCman were to add a whopping great AR coated lens to that Mt35 it could be absolutely devastating!!, though i think id pass on the XHP70 and look more towards SBT90.2
Hanks K1 does that (and more) with a 70mm head
