Today was a GREAT modding day for me. My first two real mods came out nice. My first was a duel 18650 C8 knock off I got 6 years ago. I installed a 17MM FET driver and a XHP50 on a copper MCPCB to the pill. Did a spring by-pass. WOW! At 6.49 amps this thing is like a pocked search light! The Second was My SRK 6. I re-flowed 6 new XM L2 U2 emitters, installed a custom made 3/8th’‘ copper slug to the bottom end of the MCPCB, had to bevel it so the switch wires cleared. Installed a driver from Mountain Electronics, 46mm – SRK V2 FET + 7135 Driver – SRK V2 Firmware: SRK Spec. | Ext. Tem.. – SRK V2 FW Stepdown: 90 Sec. – SRK V2 Input Voltage: 1S (~4.2V) added 4 Panasonic NCR 3400mah batteries and started to laugh when turbo came on. I LOVE THIS STUFF LOL. I am starting to have way to much fun doing this and have noticed a sizable decrease in the pocket book Silly I must admit, the reason why I love modding flashlights is the same reason I became a welder 20+ years ago. It feels good to create something and then to sit back and say, I did that. I took my newly modded SRK 6 out and compared it with my X7 Marauder just a couple hours ago, like three times lol, and the SRK out threw the X7 by quite a bit! Another great thing is the people here at BLF. If it was not for Texas Ace I would have used the wrong size emitters. The knowledge that Texas Ace and Rufusbduck gave me made my new first experience fun instead of an expensive mistake. Big Smile OK, lets see what else I can tear apart. That’s right, my new 76cc heads will be here for my 5.7l next week and I have to rebuild my engine. I’d rather mod a few lights. Silly

well, i finally took the plunge. I decided to try to machine a complete light up from round stock.

i remember someone here recently saying that when they build a light on machining? that they work on the HEAD, and the TAIL, and do the battery part last.

I went in for the battery tube, figuring once i had that done, the light will sort of “tell me” how to do the tail and head.

I made the mistake of just “going in” because i was waffling on exactly what i was gonna do.

shrugs

it was either a 12 or a 15 hour shift, i lost track. Back is killing me too, ha ha… i cant post pics yet, because I am in the middle of a “boring”, asd i dont wanna break centerline by unchucking it till at least thats done.

if i “epic fail”, i will dutifully report it for you to have a giggle…i figure if this first one “works okay” then i will call it a success.If it even looks half decent? i will call it a blazing success (and you will have to hear about it, i can about figure i could get like a little kid if i pull this off.)

it is fun though, diving right in, rolling with the punches.

With enough black coffee and cigarettes? all things are possible…

I am currently still shipping… REAL GENUINE CREE xp-g emitters, the classic… brace yourself? as low as 20 cents apiece!! Check out the SALES THREAD, everyone is happy… then PM me

Yes, I may have been guilty of mentioning the head first, tailcap secondly and the battery tube last but LTP didn’t agree with that either. Good luck on the build and give that back a rest.

My current and or voltage measurements are only relevent to anything that I measure.

@ Serp, So it looks like the Nichia has a sharp cut-off above 370nm and the aliexpress led has somewhat higher output towards the 400nm, so some purple glow is picked up by the camera (probably not visible?)

The output of the AE led looks pretty good!

Did the S2+ with Nichia have a ZWB2 filter too?

No

The burgundy paint is very bad (nose, beard on the first photo).

Without a filter a lot of extra light. I think nichia was better in this regard. I do not have it right now.
Extra glow removes the ZWB2 filter.
But, for its price it is a good UV LED Smile

Low power at 350mA
I want to put LED in lumintop tool (or made Nanjg driver @500mA for Convoy)

That’s without optics. Naked LED on the radiator.

If you are uncomfortable with sanding down 20mm filters (I still am) this might be an expensive solution:

But 12.5mm might just not fit?

So much awesomeness in one thread! Really inspiring to see the creativity and talent here, hoping to jump into modd'ing in near future but gonna be lots of baby steps to get there...

 

@lexel & djozz - forgive the ignorance but what's the purpose of blackening dedomed LED's? Wouldn't it be better to have a white/shiny surface for better reflection OTF?

 

@ZozzV6 - clever and elegant way to add magnets to a light!

I guess it is an autistic thing: a zoomie in spot modus must only show the hotspot and nothing else, no halo around the led, no rings. In actual use some stray light is often very handy but this is a compulsive thing and has not much to do with reality.

OK I figured that was the case (specific to zoomie's) but thanks for confirming!

P.S. Most likely it was an auto-correct thing but I think you meant artistic (and no, I'm not a grammar police just that autistic would totally change the context here...laughing)

Reflowed my first triple!

Haven’t connected it to a driver yet, but I did a continuity check on the jumpers to make sure they weren’t shorting, and the LEDs lit up Big Smile

I actually took the first steps towards actually having a small FOUNDRY on my property, lol… I have no idea what the neighbors will think, and dont really care.

and by “foundry”? I mean… I melted the aluminum, I adjusted the MELT… then cast it into the approximate shape I wanted… THIS resulting piece of metal? was what i started machining on, in my attempt to make a flashlight from scratch.

I know when i started fabricating with hand tools, from watching OLD LUMENS pictures of builds? I felt sort of “macho”. When i finally had my own “half a milling” setup going? Felt more “macho”. When i bought a small lathe and started to use it for more operations? I felt even more “manly” and “macho”.

but THIS? good lord, I am simply walking around sweating testosterone… LMAO.

==================================

its only baby steps in the right direction? But… if i can refine the operation and build a bigger apparatus I need? I might be able to cast a WHOLE LIGHT, ten machine out the insides, such that the entire light is one solid piece of aluminum… that would be no pill to sink losses, no sink to light body losses… nothng. It should be, i am hoping if i can make it work… other than opening the battery compartment to swap batteries? the entire whole body from inside to outside is the one gigantic “pill” and “heatsink” in one piece.

the “macho” aspect of this? It is highly labor intensive… I spent about 12 hours straight, working over a raging coal fire fed air to make it hotter… giant burns and blisters erupt INSTANTLY even through the heat-proof welding gloves… i get sunburn in the middle of winter from red-hot molten liquid aluminum… i have any number of bad cuts on my fingers from sheet metal is sharper than it looks.

i am reminded of the members name “VestureOfBlood”… IE, his name means he has “invested actual BLOOD” into his own modding and working on lights?

well, whatever “spell” was completed? I bled like a stuck pig into a vat of molten aluminum, and didnt dare drop it, because 10 hours in?? i dont want to lose all that work trying to accomplish this.

PS – this is in no way “commercially viable”, by the way… the amount of heat, the length of time, burning straight thru solid steel melt-pots in minutes… re melting mistakes over and over… all before any machining starts?? it is in no way a commercially viable thing… i am trying this just to see what its like to do it… lol

(and i am sweating testosterone all week after doing it, lol, very “macho” work)

With enough black coffee and cigarettes? all things are possible…

I am currently still shipping… REAL GENUINE CREE xp-g emitters, the classic… brace yourself? as low as 20 cents apiece!! Check out the SALES THREAD, everyone is happy… then PM me

You can buy 1 piece flashlights for example from nitecore

One is the EC4GT

But machining out the battery compartment and implement the driver will be challenging

Modded a blue Convoy S2+ host with metal clicky that I’ve had laying around for awhile.

  • Emitter: triple XPL-HI 5A2 4000K
  • Optic: Carclo 10507
  • Driver: DrJones H17F with lucidrv 2

I started by shortening the pill, the same way as on a previous mod: modding the convoy s2+ mini

After shortening the pill, I decided that rather than making this an 18500 light like the previous mod, for this mod I wanted the light to use 18650. I also wasn’t going to install a side-switch since the whole point of these newer S2+ was to take advantage of the superb metal clicky.

With the shortened pill, there was far too much space in the battery compartment for an 18650. Initially, I was thinking to try my hand at shortening the battery tube via the “human lathe” method. However with a bit more thought I realized there was a much easier way to shorten the light:

I pulled out the hacksaw and chopped the back of the head off. Then I filed a couple mm off the end of the screw threads at both ends of the battery tube. Result is a Convoy S2+ triple that is 12mm shorter than stock (104 mm modded compared to 118 mm stock). The modded light can also use the 18350 battery tube and an 18350 cell (total length 72 mm with 18350).

Additional work to be done on this light:

  • grind off the bottom-most threads on the head to make room for the battery tube o-ring (until this is done there’s no o-ring between the tube and head).
  • wait for illuminated switch assemblies to arrive.
  • possible remove blue anodizing and polish the bare aluminum.

Can you post some pictures of that foundry, your work sounds very interesting. How do you get those high temps to melt aluminum (had to look it up, almost 700 C)? Do you make some kind of molds to pour melted aluminum into?
