    hey andy i had beams that kept going shit
    put a bit of epoxy on the lens edge that will fix it
    i found i was getting shifting of the gas tape ,glue fixed it
    try it on a couple that you know are moving to test the theory first

    my dual 640 used to do it all thie time a year after using epoxy it still has not moved,
    i know glue is somthing you dont want to use , but its on gas tape so it easy to get off again if you dont like it
    best of luck m8 you will get there in the end

    I was going to recommend that, I use two small blobs of epoxy after I get my lenses to a good focus. I haven't had a lens drift out of focus yet, and its easy to remove with a razor blade if you need to.

    I have made some progress on my copy of this build, only difference is I'm trying to do it with just air cooling.

    If the epoxy fixes your lens problem, you should give it a trial run with the TEC off and see if the beams still go to crap.

    Oh and good work so far!

    Austin,

    Those are looking positively brilliant.

    I like those a lot. Nice Work!

    I can not wait to see them in person at SELEM 2011.....

    Are you selling these?

    Glueing your lenses is a must. Try pushing on a lens with your finger. I bet money it will put that diode out of alignment.

    multi-diode combiners are so fun..... after you get everything perfect and bolt it in your projector you will find you need to realign everything again. On the up side, all the work is totally worth it. 2+ watts of red is pretty sweet.

    glueing helped but i wouldnt say its the fix ive been looking for.

    i dont have any issues using glass lens so i think its just the plastic lens are crap.

    Soooo, I am behind the times on the whole combining thing. If I just want to combine 2 of those LOC diodes, is a PBS or knife edging the way to go? Seems like there has been a shift towards knife edging from what I have seen here.
