    Helmet XM-L

    Hello All,

    I finished light number two.
    This is an XM-L T6 with a Carlco 20mm optic10003 Tight Lens - LED Supply.com
    Driver is DX cheapy like the one Pucked Up used on "Easy" build (High, Med and strobe)T6 3-Mode Regulated LED Driver Circuit Board for DIY Flashlight (2500~3000mA 4.5~18V) - Free Shipping - DealExtreme
    Housing is from 1 1/8" solid bar
    Switch is remote mounted on helmetName:  mini 1.JPG

    Very nice light and machining. Waht size pack did you end up using with the DX driver?

    Looks like you need to follow the natural progression of DIY and start to anodize your lights

    Thank you Brad,

    I made a 2S pack to strap to the helmet, but plan on making a 4 battery (not sure if it will be a 4S1P or a 2S2P pack?????) to put in Camelbak.

    I have been reading up on the anodizing stuff....... maybe in the future, I feel like the first light I made is a tank and already outdated, it is only several weeks old!

    I have been thinking about flowing my on XM-L2s onto stars and doing a Taskled driver twin or triple light. I have to stop living on this forum, I am learning too much stuff!

    I blame you all!

    Who new this would be so addicting,

    Don

    HaHa, We all have been there.

    Nice build! How is the back cover held in? Kind of looks like a press-fit.

    Yes, it is a press fit. Didn't want to mess with tiny 1-72 screws, that and haven't cut threads before, nor do i have a bit to do so.......yet!

    Thank you!

    I hear that. The smallest screws I use are 2-56. My latest helmet light has 11 of then. I was sweating breaking the tap on each hole.

    Breaking off a tap is half the fun, or getting the broken tap out after, and it always seems to be the last hole that it snaps off in.

    I use M2.5 socket heads and stream hardened gun nose taps where possible. The at least have a little flex in them without breaking and don't loose there edge very readily. Carbide taps are a pain as they are too hard and snap really easily. The main key is lots of cutting fluid. No fun trying to get a tap out of a dry hole. Admittedly I have broken more taps off in aluminium than stainless steel. Doesn't make sense sometimes.

    Nice looking light
    How much does the light head weigh? I'm going to have to agree with Brad...anodising would really compliment your machining..

    Thank you!
    I wanted to weigh it but all I have is a postal scale that measures in pounds. Not very accurate, a gram scale is on my list to pick up one of these days.

    And I suppose I should pick up a power supply and hit the pool store for some chemicals.......

    The peer pressure is worse then middle and high school!!!!

    I have thank you guys for inspiring me to build lights

    I came on this forum a year and a half ago and read a thread that must have been talking about drivers and thought no way so I stumbled back on it after seeing Pucked Up's "Easy XM-L" build this past fall- Now I am hooked

    I picked up a cheap scale from Malwart....... 49 grams.

    Now I must refrain from taking all the components off the bike to weigh them and figure out how to add lightness without compromising strength......
