    Tripple XM-L

    As i have a load of LXM optics i wondered what it would be like if i used them in a tripple set up, simular to the cute 3 optic layout..
    I'm assuming they will throw further than the cute 3..
    Driver will be a B3flex... as I've still not used any of the ones i got from George..

    Here's a design i knocked up in cad, its a bit of a beast at 57mm wide and 50mm deep..
    I might be able to shave some off the width..

    Front View


    Rear view

    Looks nice mate. If you're using individual optics you could even set it up with 2 medium at the bottom and a spot on the top?

    Thanks mate...
    I'm pretty chuffed with the drawing..I sat with one of my work mates last week for 15mins, he showed me where i was going wrong trying to do 3d models in autodesk..
    Question is now, how do i calculate surface area in autodesk?

    I have loads of the LXM RS optics and was just looking to use what I've got.. plus a load of Cute 3's
    I went out the other night with my cute 3 bar light and a single XML LXM helmet light, i found that the bar light lacked punch especially through the tracks that cross the farmers fields..

    I do already have a tripple LC1 light, the optics are postions next to each other (3 in a row)..I'm hoping that positioning the 3 in this new design's config it will increase the intensity while using a simular optic LXM..

    This design is quite wider than i would like, but only 50mm long..Going to have to design a mount that lets me have the light in front or below the bars..

    AREA (subcommand Object) will give the area of a solid. Massprop will give the volume.

    Not sure which versions this works in, I'm using acad 2012, Inventor is my 3d tool.

    I would have thought 3 LXM would just give a wall of light - they're what I'd call a narrow flood, with no really spot to speak of. They don't throw as far as an LC1 or Regina at least. Perfect as a bar light IMO though.

    I'd add an LC1 or two in there if you want some more throw.

    Thanks..
    I messed with the area command..just need to make sure I set my units as inches to start with...which I didn't..
    I'm using 2012 also..

    Is it worth throwing in the 3 extra 3xXPG-2's?
    Not sure how to wire them in using one B3flex though..assuming the XPG's would have to be in parrallel, so they would only see 1amp max

    You could put the 3 XPGs in parallel and then wire them in series with the 3 XMLs, effectively giving you a 4 XML load on the B3flex. If your goal is to get some extra throw from the XPGs then sure, but if you just want raw power probably better to make this into a 4 XML light...

    I was just planning a new build using 2 XML's and substituting the 3rd XML for a triple XPG and optic with the XPG's running in parallel, will let you know how it comes out.

    Are the 10mm Carclo optics still the best for XP-G2's?
    Anybody know what the output is at 1amp?

    Not a lot to show, just milled the front pocket and starter holes for all the optics/leds and bolts...
    Now i need to centre each hole on the rotary table and mill the holes for the leds/optics

    If you want throw, I'd go with XP-E2s, otherwise you'll just be adding more flood to a floody light. Or, little mini aspheric lenses over the top of them? That'd look pretty awesome You could even slightly vary the focal distance on each one so that you don't get the "square spot in a round beam" issue.

    What are my round 10mm optic options?
    All i can find is ledil lisa, at 16° for XP-E and 24° for XP-G

    XP-E seems like it will get washed out by the XM-L's
    XP-G at 24° is probably to floody..

    I think you will not notice the output from the XP`s at all no matter what optic you use .

    However I have some tiny Aspherics kicking around if you want to give them a try you can have 3 if you want .

    Hi Chris, happy new year.

    Have you tried these aspeherics with an XP-G?
    Just wondering if its worth the effort of milling the holes for them.
    Appreciate the offer..thanks

    What's the depth of them Chris? Don't suppose you remember the focal length?
    Might not have enough room in this light!

    How much do you want for those 3? And the other bigger 3? PayPal?
    If they don't fit in this I have another idea for them.

    Thanks

    Quick update...
    This one I'm going to keep as a tripple LED set up, but ill use the new XM-L2's..
    I'll make another and hopefully fit in the 6 LED's..possible using the 6 aspheric lens i got from troutie (thanks Chris)

    I'll need to mount the switch in the side of the light, as i just dont have enough depth in the driver compartment to mount the switch in the rear cover..


    Still need to chamfer the led holes on the front cover

    and take the LED/optic holes down to the correct depth in the body..Initial plan is to use the optics without there holder..

    Rear cover will have just the M8 cable gland..not mad my mind up exactly where..

    Pedastal to stick the B3flex to..

    And of course mill some sexy fins and loose some weight!!

    what size end mill do you use for the o-ring slot and what size o-ring - you use o-ring string, right? Beautifully clean machining too.

    Cheers for the comments guys..

    Vanc - Your not wrong, it is a bunch of work on my little rotary table! I really could do with a 120mm chuck at least!
    Having to locate each of the 3 led holes is a bit time consuming.. Had to do that on the front plate to mill the chamfer, as i didnt have enough room in the Z axis!
    I milled the holes both in the front plate and body by using a slot drill and stepping up in sizes up to my biggest slot drill (16mm)
    Then i used my boring head and shaved the holes to 20mm. That gave me a decent sized hole to locate the centre of, using a DTI.
    I then milled each led hole to the correct depth and width!

    Regarding the fins, not 100% sure yet..really wanted to be able to tilt my rotary table!

    Here's where the switch will go - ignore the two holes in the back plate..


    Today i sorted the business end out..




    Matt i use 1mm o-ring chord.. face groove needs to be 1.40mm wide and 0.65mm deep..
    I use this for the measurements..
    O-Ring Metric & Inch Groove Dimensions

    As for a mount, i want this to be under the bars - so need to come up with something.

    thanks for the link GD, that's a very useful resource. I might have to order some stuff in the UK, finding metric stuff in imperial land is no fun.

    looking great though, plus you'll be able to swap optics in and out if you want to try something different. Those LED-DNA optics would work well mixed in with the LXMs.

    Not much progress at the moment..
    Decided putting the switch in the top was to tight so went for the conventional in the rear cover..
    Finned the rear cover to shave some weight!

    Nice work Jay. I had forgotten you don't have a lathe and therefore have to cut everything with the rotary table and the mill. You are certainly a pro at it.

    How long does the rotary table keep spinning after you stop turning it

    Thanks Brad...

    It's still spinning now..12 hours later..
    I keep meaning to fit a motor to it and also keep the manual handle...but time is short with my little boy...
    He does love to sit on my knee and watch me on the mill..

    I think I saw somewhere where someone had rigged up a corded variable speed drill to their manual handle to turn the rotary table.

    Thanks Matt,
    My wife is so pleased its finished....as shes thinks thats me off the mill now....


    I cant see any reason why you cant do anything like what I've done, using a milling attachment on a lathe...
    Its basically the same setup, apart from i have a rotary table with a chuck - you have a chuck on a motor...
    I need a lathe!!!

    it's more just a question of scale and horsepower (or lack of) really, but we'll see I have a couple more small projects (work lights etc) do gain skills on before I consider starting on a proper light.

    I do have an on-off switch now though and a motor tie down, both of which I'm inexplicably happy about

    Looking forward to the finished product GD - any sense of how much longer it'll take?

    Matt, do you mean anodise and get it wired up?
    I need to redo my cad drawing to workout the surface area, for anodising. Autodesk gets a bit messed up sometimes with 3d...something to do with the csg tree.

    Polish might take 1.5 hours
    Anodising 4 hours
    Wiring 1-2 hours

    I'd like to get it done on Sunday...but depends if my wife is going to moan

    Brad...
    Thanks for the comments..
    Only part I don't like is what I did to the front of the body...seemed a good idea at the time.

    Don't forgot to put honey or Jam on your wife's toast..

    Are you using inventor or solidworks?

    Jay I am using inventor pro 2011.

    Now your married your wife should be happy with anything that makes you happy, like watching sport, making lights, procrastinating over the list of jobs she has written for you, drinking beer with mates. Your penance is having to endure looking at shoes and handbags when you go shopping.

    I like the idea of some honey on her toast. That will get me in the good books for sure
