    Build Your Own Aluminum Flashlight video

    Here is a video which shows how to make your own Aluminum Flashlight using a Surefire 6P style drop-in. Hope someone finds this useful. BTW; I do not sell these flashlights, but just make them for friends/family. https://youtu.be/xIrR3EXEcUE

    Custom 3x-18650 6061-T6 Flashlight

    I should have mentioned that the Digital Machinist article shown in the following thread does go into some detail about how the engraving, coloring, and polishing is done. http://www.candlepowerforums.com/vb/showthread.php?t=236547&referrerid=75116

    Custom 3x-18650 6061-T6 Flashlight

    The color is Dykem Staining Colors, sold by Enco/MSC/etc. It is similar to Dykem Layout Fluid, but has some solids so is not nearly as tranparent yet drys to only a couple of thousands thick. I have used other colors as well, but none look as good with polished aluminum as does Black. Some...

    Custom 3x-18650 6061-T6 Flashlight

    Polishing for many of the turned surfaces is simply a matter of using a good metal polish (Mothers brand is my favorite) and soft, cotton cloth. For the surfaces which are engraved and colored, it is much more work. I first sandblast the surface so that the color will adhere and then must...

    Custom 2x-CR123A 6061-T6 Flashlight

    Actually, all lathe work was done on a manual lathe. The only mill work is a recess for an internal machine screw, cutting out the lens (window) and copper clad (PCB, for spring plate), and engraving. Everything but engraving could be done an a manual mill (but would be good to have a rotary...

    The batteries are in series. Here is a link to the thread I just started to show the battery holder I made for these flashlights: http://www.candlepowerforums.com/vb/showthread.php?t=236645&referrerid=75116 Sorry, have no beam shots or runtimes. On Low, the power consumption is 2W and...

    Custom 3x-18650 Battery Holder

    For a couple of my custom flashlights, I needed a battery holder for three 18650 cells. Having taken inspiration from turboferret and modamag, here is what I came up with. The material is black Acetal (e.g. Delrin) which started as 2" round rod. It was first turned down to the needed diameter on...

    Custom 3x-18650 6061-T6 Flashlight

    Here are some photos of my latest flashlights. These use three 18650 LiIon cells, a SSC P7 emitter, and a 3-mode driver. They were made using both 2-1/4" and 2-3/4" 6061 round rod, except for the switch-surround which was milled from 1/2" 6061 plate. Milling/engraving was done on a Taig CNC...

    Custom 2x-CR123A 6061-T6 Flashlight

    Here is a photo of my first attempt at designing/machining a flashlight, the construction of which was featured on the cover of Digital Machinist magazine, Summer 2008 issue. It uses two CR123A cells and a Surefire P60/P60L. While not the fanciest of flashlights, it is a good, intermediate...

    Eric; You have gotten me more curious so I decided to do a mini teardown of the TL-100 and take a few more measurements. Here is a summary: Charger: Tenegy charger for 16340, 18650, and 17670 Li-ion Battery: Tenegy 2600 mAh protected cell Multimeter: Fluke 79 III AC-to-DC adapter is rated as...

    AC adpater replacement on Tenergy TL-100 charger

    Eric; Thank you very much for the useful information. I placed a single 18650 cell (partially discharged) into the charger circuit such that I could measure the charging current, and measured just over 0.2 A. Thus it appears well under 1C. Bob

    AC adpater replacement on Tenergy TL-100 charger

    Will a Tenergy TL100 charger charge a single 18650 at twice the rate of two 18650 cells? And is the charger intended to be used to charge a single 18650 cell?
