boring a 6p

[adam38654]

Does anyone still offer services to bore a SF 6p for 18650's?

16650 have a pretty big capacity nowadays. Might be better to use them then to thin out your walls.

I do run them in some of my original surefires but wanted to trick this one out with a triple Nichia 219 and mcclicky tail cap. I am also in the States.

Are there any good 16650 available now? The Sanyos are discontinued and the Keeppowers are almost $20 each.

Orbtronics are under 10 bucks and i have no complaints about their performance.

I have a bored out 6P that I wouldn't mind trading for an unmodified 6P. Would you interested in a trade?

I have the proper tooling for boring, did three heavily-used Elzetta Bravos just the other day. I use adjustable reamers to keep it centred, and then polish with sandpaper for a nice finish. These went out to 18.70mm for a snug fit on Panasonic 3500mAh wrapped cells.

@KTFlights also bores Surefire, fwiw.

Not hard to do it yourself, get yourself 3/4 flex hone, put it in a drill, and carefully , at low speed bore the tube out. it will take time, flex hones do not remove a lot of metal with 1 pass, do not go fast or you'll clog the hone. I did it with aluminum tubes for something other than flashlights, so i know it works. the only difference is, lights may have anodizing on the inside of the tube, so it will take a bit longer to file off the hard anodized layer, once it is gone, things will go faster

Not entirely certain, but I believe KTFlights bores with a lathe. YMMV.

another vote for Orbtronics 16650. they are made in Japan and 2190 mAH. Very reliable.

FWIW, Orbtronic 16650 are made in Japan because they are rewrapped and protected Sanyo UR16650ZTA limited to 4.20V, exactly like Keeppower 16650.

Very logical, he owns a lathe so he uses it to bores out tubes, those that do not have lathes, use other means that also work.

I did my 6P with a piece of 1/2" aluminum rod chucked in a drill and a lot of sandpaper and duct tape. It made a mess, but to me it's worth it to be able to tap into the plethora of 18650's out there.

 

[desert.snake]

I bore mine with a round file, then I made a nozzle on a drill from sandpaper to smooth the surface a little. Works well, but you have to constantly check inserting and removing the 18650 to check if you removed too much metal, also the hole is not quite round

 

[chillinn]

also the hole is not quite round

Thank you for your honesty!
