Hi everyone.

After I failed my Arctic Modification Project (1V loss at the tailcap using a boost drive... This host should just be locked away) I started searching another host which works of a 18650 and has good heat sink capabilities. After searching I came across "lazeerer's Personal C6" and really loved the idea.
I decidet to do a similar build using a Survival Lasers S4 host.
The bad thing was I had absolutely 0 experience using a lathe. So it was time to get some...^^



After polishing it got blasted with glass beads and anodized in black. I did this to get a close finish to the original finish. I got no pictures from the single steps because I always have bad luck when making pictures, but I actually had to do every step 2 times because I ruined the thread inside the heat sink.



The main piece is over 130g of Aluminum. When I tested my diode inside the host to see its output It got barely warm, no comparision to a standart sized C6 heat sink...

The finish I tried to get with blasting and anodizing turned out very nice but you can see the difference to the other parts of the host, even though in real its a tiny bit less obvious than in the pictures. :whistle:



The main part fits 2 o-rings to hold the focusing adapter tight and makes it harder to turn but also smooth. It works out really nice, no need for a spring or anything (But I think I will still add one :p)



The heat sink is directly threated to be screwed on the S4. This thread and a little bit to much sodium hydroxide ruined my complete first attempt just one step before beeing finished... :mad:





Im still waiting for some parts to finish this laser. (Mostly contact parts but also a new S4... When working on the parts it fell down and got some damage. Its not that bad but its really disturbing me, so I will replace them and use the old for a smaller project...

The diode (M140) will be powered by 2 "ancient" micro boost drives each at 900mA. Maybe I will replace them if I find some nice boost drive running 1.8A from a single Li-Ion cell. But my tests showed 2 drives can go pretty low until they start to reduce the output.

And to prevent the swich from being roasted I replaced it with a McClicky. :D

So I hope my missing parts will soon arrive so I can put everything together and finally have my first Laser over 2W... :)
