The bottom ones look like header pins
Female headers (just solder wire on for quick connect)
Rufusbduck, sorry I was rude with âseems like a waste to pay oshppark for that.â 
What diameter SMD button PCBs does the SRK and clones use? Usual button?
It has 3mm holes (actually via's) so that I can solder 3mm brass rods in, but other materials can be used if you use screws (even M3 threaded rod can be used with nuts), the rods are not part of the electrical path (apart from that they are connected to batt - )
Helios
. I use brass tube for a ton of things as it can be tapped inside or threaded outside and there are nylon bushings available at the hardware store to use as insulated spacers. Also threaded nylon screws can be had in 6-32and 8-32. The nylon is nice in that you can solder near it without it melting or deforming which is why I use it for the sleeve over 7135 stacks.
Made a tact switch (button) board. Standard 2.54 mm header pins fit on the back. Semi-universal as far as 4 pin buttons go. 4x4 - 6x6mm smd and through hole 6x6 should fit.
12mm dia with 10mm silkscreen guide. Any particular diameters wanted? So that cutting isnât needed much.
Also did an smd only version with tiny tented (soldermask covered) vias. Set it in with RTV silicone around the edge and it should block water from entering the driver cavity.
2.54mm header pins. 2.54mm (0.1â) is standard pitch / pin spacing. There are also 2.54mm machine header pins (round pins) which usually cost a bit more. Normal (square) pins wonât fit into female machine pin connectors.
You can also get XH2.54 connectors. Same pins but shrouded & keyed to prevent plugging in backwards.
Cool! :beer: So that's 12mm square, and 10mm at the ring?
edit: Erm, I just now measured the SRK switch hole, the ID is .480"/12.2mm... so either 12mm round or add a second cut line outboard at 12mm. I can't cut/file (or even draw!) a circle freehand that ends up even marginally round to save my life.
edit2: The nicer/genuine SRKs have a 1mm o-ring behind the switch PCB in the bottom of the bore, the cheap ones don't even try.
Ordered 3x 15DD, 6x17DD, and 3x20DD
OH YEAH!
I might have to order some more FETâsâŠ
:bigsmile:
Which board is this?
Now that looks awesome. Any feedback on the layout Comfy?
Itâs the SRK FET 46 mm driver listed in the OP. It looks real sweet you guys.
AWESOME!!!
I see you cut a notch for âeasy removalâ 
BeautifulâŠjust got mine in today and incredible soldering comfy! AWESOME, pure awesome!
Oh yeah and comfyâŠany problems with the 1.6mm thickness vs the 2mm of stock drivers?
Canât wait for a âreviewâ and stats of the board
Thatâs slicker than dear guts on a door knob. Do you guys think it will fit into an M6 as well?
What is the diameter of the driver?
46mm
I'm an Idiot lol. SureFire M6?
It would be real handy if the first post included links to the posts here at BLF pertaining to each individual project.
The 46 might not fitâŠbut the 17 or 20mm will 
The only little thing I can find is that the pin2/pin3 selector thing for the switch input could be tricky when removing/replacing the switch wires, if it's done at the driver (if you use a wire lead to bridge the gap, the soldering iron will tend to suck it up when removing the switch wire). But I tend to tear things apart and tinker much more than most 'normal' people, and I plan to still add a 2 pin header on the little switch PCB for that reason anyway, I don't like unsoldering stuff when I don't have to. That's a very minor thing and I'm weird, it will probably never be an issue.
Warhawk, I dunno, but Richard is going to be selling them, gotta mod one. Gotta! That driver is just compelling. I feel drawn to it like a moth to a flame. (And if you have seen me solder than youâd know that analogy fits perfect). I figured one of you knew. I will do a search on some of the reviews.
Matt, an idiot? Not from what I have seen. A poorly phrased question I will grant.
