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

Received my order today including the X5 kit, the packaging is very good and the shipping to Denmark is very fast.
The X5 is a little beast, with a MTN-17DDm driver, quad Nichia 219C D320 and a fresh Windyfire 600mAh battery I get 11,87 A initially dropping like a rock to 8,5 A after about 30 sec.

I was going to use XP-E2 for the M1 quad but I don’t know how they like a FET+1 driver.

You can try them with regular cells like 26f, 29e and etc.
XP-E2 should fit those optics well.

Need some advice about this option.
Due technical reasons, solid neck+18350 extender should be at least 5mm longer, than 18350 host. This way driver place will be 10mm upper.
P60 extender tubes are full length (bigger one can fit 70mm cells) so this extra 10mm are excess.
18500 cells are not very popular.
10 more mms, and non-protected 18650 cells will fit this tadpole.
What do you think?

possible product idea.
Just bought a couple Lumitop copper Tool on sale for cheap. Never bought one before cause I dislike the Honkin’ tail cap Switch.

Is it possible to get a cap made to turn the Cu Tool to twisty?
By design it would work.

No, this is not possible due lots of reasons:
-in such parts, smaller does not means cheaper
-surface roughness that we can achieve is not good enought for external parts with difficult shape
-to get twisty with full copper light you need isulated coated internal threads. Impossible under thousands qty.
The only thing I can suggest you, if you dont like tail rubber cap and switch intself, you can think about making solid insert to stock tail that will change stock switch and cap. It can be mafe from any material, can provide waterproof with o-ring, will be much cheaper than whole tail.

any chance you would be interested in making aluminium tail-switch-part-thing for Convoy C8 flashlights that could be used to make remote pressure switch? Just like regular pressure remote switch but only aluminium part, without the wire and the rest … ?

I dont know what are the problems with the existing parts and why you cant use them, but if you can help with the drawing, why not?

Threads are the problem, convoy is using square threads, everyone else have V shaped threads.
I don’t really know how would I measure that, don’t have thread gauge.

Why you cant use stock Convoy v3 tail with internals from remote swich made for chinese C8?

If I were to buy one I’d only consider 18650 and 18350.

Simon has a remote pressure switch in the works.

Let it be so.
18350 - head+neck+tail
18650 - head+neck+short extender+tail
Both should be about 18mm shorter than stock hosts with short/standart extender.
Neck have about 12mm legth external surface (d=31.7). I think that fins could not be made well on copper at this moment, so I think this surface will be just polished.
If they will be made from aluminium in future, some ribs with 3.5mm height can be added there. I would like to try some coating on one of such part but unfortunatly small quantities killing this idea.
P.S. Have forgot one important thing. Driver place is far away from the tail side of this project so simple desicions wont work. It will have screw-in from top pill with driver retaining. Bigger one for carclo triple/quad and smaller one for carclo 26.5mm single optics.

External finish does not bother me at all. Plain is perfectly fine. Machine marks are fine.
Completely lost me on the thread coating. Why? driver is the insulated part and only turns on with body contacting it. It already works perfectly fine as a 1/4 Turn twisty of the head with the switch ON. By it’s current design, it will work as a twisty.

If you want to rotate head (not tail) it will work without coating.
I just need to understand why you dont want to make such improvement with simple insert?
Can you make simple hand drawing, what do you have know and what do you want to receive?

I received my order today, 2 weeks from Russia to Canada, well packed and everything very nice !
Thanks

Received my order today and am very happy about it. :smiley:

Do you mean something like this Tool tailcap , just made out of copper?

Is the sk68 copper pill on or off the table? You had a short list going. Some other good things you’re doing here.

No kidding. Thanks but Yes copper is essential
Thanks, should have looked.
