I'm at the point where i always break my lasers! Ive taken the head off, and now im at the part where there is the alunimum metal that appears to be glued (i think) in the body. I'm not sure how to go about taking this out.
What i would like to do with my laser is get to the mainboard so I can solder the switch to always be on, using my tailcap as an on/off switch. I'm using my KD 150mW Focusable Baton Style laser btw. here is a picture of where im at.
I just need help removing the last part!
