I fine tuned the fitment of a heat sink I made for another forum member, boy is it hot out there! We still have 2 months of summer to go, easy….
I put an old mercury thermometer on the central support column the other day, big 4x8 wood beam, so the thermometer is in the center of the shop, away from exterior walls by about 20’ and some 12-13’ from the peak of the roof, directly behind the lathe. It’s 104º in the shade, no air movement at all. Wicked! That’s 39.5ºC for y’all that don’t do Fahrenheit.
It is bright, gets hot really quick. I spent a lot of time learning how to do things. Then about an hour to recognize that reflector was doing short circuit…from the temperature one spring collapsed due to hot, but fortunately - nothing else was burned.
Since I was using regular Convoy light - not the host - I had to desloder the driver from pill….that was really difficult. How do you do this?
Afer that - another challenge was to solder new driver in place…maybe you have also some hint for this?
Of coarse, but I’m designing a headlamp that will be made from aluminum (CNC machining). This is just a protoype test to see if I want to make a triple headlamp alu case. I don’t think so though, I’’ll probably pursue my other expensive “cheapo” prototype: Build: Dual XP-L headlight project.
I made up an extension ring for a DQG 26650 to take a Khatod optic. I haven’t filled it with running gear yet. The thread onto the body worked out a little bit tight but I think it’s a good thing because I notched a groove in the extension ring for the optic to sit flat ie the optic has a nob on one side from manufacturing (I guess that’s what it is…?). Now the optic won’t try to spin when I screw the bezel on and off :sunglasses:
Edit: just rotate the optic some 60º and put a new slot in the adapter ring, lining up the TIR’s and still keeping the notch, albeit on a near opposite side.
Sputtering in this context is fogging the surface with sparse droplets of a clear finish that doesn’t yellow much, it breaks up beam artifacts. There ought to be some posts here on it, I know OL has done some. As opposed to sputtering in outrage though the pictures brought to mind might be similar.
sk68 clone.
Part of host threads are cutted off, sliding tube is fixed in lowest position.
Custom copper pill, XP-E2 triple with Carclo lens under 20mm glass.
P.S. I have lots of this hosts and pills but no time at all so I can send them to anyone who will pay shipping cost.
Yes, sipik AA clone host without stock pill with copper one. Parts may look not good and sometimed requires lots of hand work time (which I dont have).
Need to check how many they I have. I suppose 15-20 sets.
Would love one set if shipping is reasonable, i would love to try and assemble one if it is possible only by hand work, don’t have any power tools for the job.
