Another project piece arrived late yesterday afternoon, I now have the Sofirn Q8 and a 4 pound chunk of Aluminum that are engaged to be married soon, maybe even today!
The marriage of 4âx3.25â 6061 bar stock to Sofirn Q8 in a private ceremony conducted by Reverend Dr. Frankendale took place this morning. The ceremony was about 3 1/2 hours, seems the 6061 had cold feet and needed some persuading.
The couple are now bonded and anxiously await the arrival of their little ones so they can begin their happy but exhausting life togetherâŚ
They plan a rather large family, expecting 12 Samsung LH351D 80 CRI 5000K and 4 Cree XP-L HI V3 3A to pair up with Noctigon Quad MCPCBâs and Ledil Angie optics. Should be a rather enlightening experience.
WowâŚ. that looks like the beginnings to a happy & bright future!! Best wishes to the happy couple as they anxiously await their âlitterâ of chirenââŚ.
This 4â x 3.25â piece of 6061 was 4 lbs to begin with, more stock removal will be required for the emitters and then Iâll cut fins and shape it so quite a bit of weight loss will still occur.
Edit: Just mating it to the Q8 took it down to 2 lbs and 13/16. So I have a pound a 3/16 of shavings off this chunk already. lol
Got some more preparation done on the Q8 41 MAG today. Some new plans have a little bit of a twist, a center reflector to add some punch down the middle. Reflector from an X5, emitter to be determined but I am pretty sure which one Iâll use. I plan to utilize the original driver with MOSFET and 7135 chip exchanged to match what I put on slave boards, so the original driver will be Master and I will have 4 slaves, the Master will run the center reflectored emitter and each of the slaves will run the 4 quadâs populated with Samsung emitters, for a total of 17 emitters. Projected output is in the 26,000 lumen range.
I know the pic here shows an HI in the middle, but that has changed. lol I will have to inset the MCPCB with the emitter in the center to allow for the deeper reflector, and I will have to cut the optics to meet the reflector but only a little, the cut curve will be where one of the 4 legs is so there will be that one sacrifice. Shouldnât matter. The X5 reflector has an outer shelf for an o-ring that Iâm thinking will catch the optic and pin it to the glass lens, so the leg wonât be missed. Will see.
Todayâs work ended up with the light in this condition. Ready to inset the center board, the 4 quads should be ready to go in. I have a glass lens that fits but Iâll need to make some adjustments to the bezel as this lens is thicker than Iâd planned, may still go ahead and order a UCLp for maximum throughputâŚ
When Iâm nearer to finished Iâll make aesthetic changes and cut cooling fins.
This morning I inset the center MCPCB and reflector. I found a reflector that is a little smaller than the X5 I was going to use, this should allow me to use the 4 Ledil Angieâs on the Noctigon 33mm Quad MCPCBâs without cutting any on the optics.
26mm Maxtoch copper MCPCB with XM footprint. Iâll be using a de-domed SST-40 for the center punch. As you can see, I started to cut the remaining shelf to be ready for the boards and optics but decided to wait til I had them in hand to be sure of the depth. I COULD disassemble my D4S and check this measurement but so far Iâm waiting. lol The shelf is at 10mm and the math makes me think I need 12.7mm, but I donât know for sure so itâs wait time. The Maxtoch MCPCB and reflector required a 17.7mm depth, hence the inset.
Difficult to see in the picture but there is an AR coated glass lens in place⌠the lens from my BTU Shocker just happens to fit perfectly albeit a bit thicker than Iâd planned. Will wait and not inset that for a perfect fit as I have sent a message to Chris to make a 95mm UCLpâŚ
Edit: So yes, there will be 5 drivers to 5 âlightsâ within this one head, essentially 4 D4S lights with a modified 22mm tube light sporting a de-domed SST-40 for throw down the middle. Should be interesting to see what Sofirnâs carriers can do. 4 quads plus the one reflector, hence 41 in the name, and the MAG is a spinoff of both Magnum power and the acronym Most Audacious Guffaw, to poke fun of Giggles for the name of a flashlight. 25,000 lumens should get a pretty good gut laugh, yes?
Today I researched the specs on the Ledil Angie and Noctigon quad MCPCB, made sure what depth Iâd need between the emitter shelf and lens. Then I went out and cut the shelf to the right depth. Recessed the lens shelf in the bezel so the 2.2mm UCLp will fit properly. Then I cut fins in the bulk of the body. This is the part I really have the most trouble with on this lathe, using the parting tool. But it was being nice today so I went ahead and got the big head ready for mounting emitters. I can use a drill press I have on the back porch to do the rest of the assembly once I get the remaining pieces.
This Sofirn Q8 is all primed and ready to become a monster.
I would like to shape the rear of this big head down towards the Q8, but I wonât do that until itâs running and shows me how it handles heat. No need to remove cooling mass if it is going to be needed, and it may well be that even this is not enough.
Iâm getting a strong feeling that the cells wonât be able to supply the power I want, especially in the carriers. I will probably have to fortify those but it remains a question as to whether or not Iâll be able to feed all these emitters.
Edit: I might have to make a new battery tube to hold 4 21700 30Tâs.
I donât think so Jason, the aches and pains created thus far thoroughly convince me that drilling and tapping 10 small holes would not be in my best interest. I will use Arctic Alumina Thermal Adhesive and apply pressure while it cures, the lens will press down on the 5 pieces as well so I will use the lens in the mounting process and either a weight or my tabletop vice. I have the 3mm thick glass lens I can use, 95mm UCLp is on the way for the final. This should serve the purpose, will have to do.
Noctigon MCPCBâs and Optics have landed in Chicago, estimated delivery is Tuesday.
Need to get busy building the 4 Slave drivers and set that all up on the Master. Also need to drill for wires to run. About 10 hours in and plenty to do stillâŚ
