    What do I need to fix this part of my laser

    Thanks for all replies and tips. Some of the gray flakes (whatever it is) was on the threads under the lens cap and some actually on the lens and down around diode. I carefully cleaned all of it. I took a low speed wire brush to all copper threads and made it shiny new again. Snugged it up...

    So after messing around with this a while, I figured out I could snug the module down inside the host. I don't have a specific tool. I just used a tacky glove to hold the module and snug it tight. Put the lens cap back on and so far so good. So should I still get a thermal paste for the...

    Sanwu Pocket 445nm 500+mw

    Received my Pocket 445nm from Sanwu. Podo sent me vid of LPM of my laser. It was still climbing fairly quickly at 584mw when he stopped the test. I'm guessing it's actually 600mw+. I got the G7 lens. Time shipped to my door was 18 days. Next one I order will be expedited. Learned a...
