CRX FW3A Mods & Teardown

Thanks, feel free to steal any pictures you find useful for your troubleshooting thread.

For posterity.

On a more serious note, I love the tail switch mod.

Thanks for the very detailed mod overview, and the great pictures!
Excellent work, as usual :slight_smile:

Your welcome & I will… as well as put a link to this thread. :beer:

Something I don't quite get - is the glass vial taking the pressure of depressing the switch? If not, not sure how it's avoided.

Great mods! Was thinking the same.

I would have preferred to use a 6mm x 1.5mm vial but only had a 2mm on hand.
The UV glue helps support it at the sides, it is level with the bottom of the vial so takes some pressure but the underside of the vial is bare though it doesn’t take much pressure to operate the switch and it sits on top of the rubber so I’ll see how it lasts.
A very hard direct bump to the switch might break the vial as it is but between the rubber and the wide membrane type switch it should be ok.
Kinda like when you install a vial through the rubber switch boot posts.

Fantastic work, CRX. I’m admiring and jealous at the same time. :wink:

Sure would’ve been great if a trit slot had been cut into the tail cap… But it seems like it’s not deep enough.

Thanks.
Thing is though it could be deep enough, I was expecting a lot more hassle trying to get it working properly, especially with the thicker vial but all I did was cut the nubbin off.
If the switch cover was made with the vial recess very thin it should work just fine with a little mod to the rubber boot.
The top switch cover is around 0.5mm thick if I remember right, plus it had a 0.4mm nub on it and then you have another 1.5mm space with the rubber nubbin removed.
Well, that’s a word I never thought I would write more than once in a lifetime… :laughing:

Flickin’ nubbins when clubbin’ will get you a drubbin. :wink:

Yeah, given what you said, seems like one could cut a slot all the way through. I have a SOG Vulcan Tanto San Mai with 3 cut slots in the blade. I discovered two were large enough to fit some trit vials. Because the slots were cut all the way through, I taped up one side to keep the Norland from leaking through. So same technique could be used for installing one on a slotted button cover.

Nice. That is exactly what I do, tape one side or put tape on a very flat surface, hold the item down and apply the glue :+1:

Hhmm - sounds like same trick I do using tape on the inner pill side to fill in USB charging holes with epoxy. I've been using kapton tape actually, and JB Weld. No pics though...

Great minds think alike! :smiley: :+1:

I like taking $10 lights and making something useful and nice out of them:

Left handed?

yep

Awesome mod CRX! :+1: :beer:

:wink: :+1:

CRX - in swapping to the Noctigon, did you sand it down or did the thickness work out ok or handled in another way?

Also interested in this since I have a L4P all ready to go waiting for a FW3A, lol.
