Low-cost copper pills, spacers, optics, drop-ins (Updated 23/10/2022))

Need a person who wants to make a belt grinder from an angle grinder. ASAP.

kiriba-ru, would it be possible to make a short 18350 tube for the Convoy C8? I can’t find one anywhere and I like short flashlight versions like the GT mini.

Had few requests but defenetly not enough for cnc batch.

Thank you, kiriba-ru! Looking forward to the day when Convoy will produce one.

Hi kiriba, I would need:
2 x P60 Surefire copper quad shelf (Convoy retaining ring), 22.00mm – $12
1 x Maglite D kit Aluminium drop-in+copper pill, fit 30mm driver – $12
1 x Driver brass adapter: 20/22mm press fit – $3
1x 17mm with retaining ring – $4/$7

Can you send PM with payment details please

How much?

I have PMed Cereal_killer, but also need to leave a message here to make it clear.
I dont ask any money and not ready to pay, I have 3 sets of wheels for BLF members. If you have an idea about other materials you will need, I will try to help with them too. The way you will build it doesnt matter (for example I dont have welder). Just make cool photos and video of the process and working machine.

Your C8TT triple heatsink head shows “$35 shipped”. Does that mean shipping is included? Another question: What diameter and height does the Copper spacer Ultrafire F13 have?

Yes it means it is spare shipping and price is included.
F13 spacer have many steps and sizes.

I thought about using the copper spacer for a triple or quad build with a Chinese flashlight. But if shipping is included with this head I might as well get a Convoy C8 with the nice option of swapping the heads then. The price is reasonable and I really like the design with very deep heatsinking grooves and the SS bezel.

Here’s my C8TT sucking down nearly 30amps like a champ. You guys need to go buy up all his stuff right now so I can convince him to make more cool things for me to play with.

Full build details at the daily mod thread:




contactcr that looks really cool. How’s the tint? Does it look below the BBL? Also I heard when you mix two different CCT too far apart in parallel, it can be a problem because their Vf might be very different.

Im guessing slightly under 5k. Ill try to compare to a known 4k and 5k tonight. I dont see any magenta or green so i can only guess it’s close. I have not ever seen either emitter by itself before this so im not sure of that either. First time using MZ.

As for vf hopefully since both are same CRI its close. Plus they can take much higher current in total so maybe that helps too?

I checked the color temp and the closest known one I have to it is a XPL HI U6-4C 4200-4500K so it must be closer to 4500K than I originally thought. This actually makes more sense because if the split was even it would be 4350K but I assume the 5700K contributes a bit more so round up to ~45K?

Yea I would assume since the 5700k is a higher bin. Wouldn’t be surprised if it is more like 4900k. But very nice. I might get one too to tint mix.

Knowing how particular you are about tint and stuff I would not pair de-domed LEDs with Cute 4 smooth spot. I ordered a medium spot replacement optic in the hopes that it will get rid of the donut in the middle.

CUTE-4 optics is unfortunately made only for ancient Cree XR-E led so tir holes are quite far away from pcb surface.Part of emitted light from undomed thin LEDs like MZ doens't hit tir hole (or hits at wrong angle), so there is some lumen loss. Luxeon V + Cute-4 works much better because LED is domed. Cute-3 works nice for all LEDs,including MZ.

I’m interested in a full copper pill for doing a triple convoy S2+ build.

Let me know!!

Im sorry for delays, I know many members are waiting my parts, I rememember each quest and will make all parts Ive promised.
I can roughly estimate sequence of restock:

- copper pills single led S2+ (mtn boost driver compatible)

- custom parts from pm requests, including p60 single led and b158 pills, new design custom retaining rings

  • triple pills and spacers for S2+ (probably next month).

Still need in reviewer of belt grinder parts, open for any help!
