Well I was going to use this build as my 1000th post but I guess I lost track of my post count. Oh well. Was trying to stick to tradition.

This host was the second thing I ever purchased from LPF. I got it from Mrcrouse while I was still deployed. I dove into the hobby hard and ended up purchasing a total of 4 S06Js for this host. First two I killed, second one I gave up and put in a B50 host and the 4th one sat in a drawer for months.

Here is the build. Hope you enjoy!



First off all I'd like to talk about the heatsink. This thing was trouble from the beginning. It was a direct press fit for a 5.6mm diode except the hole was worn and about 5.65mm. The diode just dropped right in. This is where the first diode died. Being new I thought that that was as tight as it was supposed to be. Turns out at 500mA and no heatsink they don't last long. Figured out quick I needed to have a new one made to proper tolerances. Sent it off to Flaminpyro to get made out of copper. Lucky me the heatsink strikes again. It was the only thread that Flaminpyro couldn't get set up on the lathe. Determined to build this laser I thought up a plan and sent it to him.

I had him bore out the old heatsink for a 12mm module and shave the threads out of a 5.6mm module. You will see why later.



The lens doesn't screw into the module like a normal build. Instead it screws into this focusing mechanism that an external focusing adapter screws too. So the lens has to move freely up and down the module on a different tapper of thread. Hence the clean shaved walls of module.



Like so:



Soldered the Microboost set at 450mA from DTR (diode and lens also from DTR) directly to the pins. Used the case pin to pull positive from the host to feed the driver. Looks sweet the way it wraps around!



Installed the module with driver into the heatsink and tightened down both set screws.



First in (not pictured) was the lens assembly, following that the heatsink with a standard spring in the module for a little back pressure. Used epoxy to "spot weld" the heatsink in its final location. Did the same thing for the lens in the lens assembly.



Here you can see that lens assembly sticking out through the front with the focusing part screwed on. There is a dab of epoxy on the threads here to keep it from unscrewing.



Next piece on is the center portion that connects the head to the battery tube and also helps hold the plastic insert with the negative spring.





Build is picking up speed. On screws the battery tube.



The front "crown" Can unscrew and use the different lens they have if I had any.



In pops an 18650 sealed in tight by the tailcap and voila. Its been a long long wait.



Not sure why the graph is weird. It has done this to me a couple times before. 688 average!



Was a long day at work so don't feel like pulling out the fog.

Here she sits a burning atop my recto.




As always, what do you guys think?

That's nice.. Really like how it turned out looking. Very unique and 700mW is quite a bit of power for the 405nm!

Uh. We will see around Christmas time. Will be selling off quite a few things in preperation for the birth of my first child. I really like this laser though so I dont know.
