I don’t think I’m up to making any more videos. Even I have to admit they’re not that interesting.
I have a tail now … If you look back at the very first pic of all the parts you’ll see the bar stock has knurling at each end. This is one of those ends. I nearly ran out of stock I seem to have produced a fair amount of waste.
Some of the threads look dirty because I used some metal polish to work the threads and smooth out the gritty feel. There’s also a few things to clean up like cutting the tail to exact size and a recess for the o-ring etc… Once it’s all cleaned up then I can start assembling and soldering. Nearly there
Wonder what the scrap value is? I save copper cutoffs from all the solar system wiring I do. If I strip the insulation the last batch brought almost $2.50 a pound.
Mostly done with this light now. Lathe work is all done. Driver has a little heatsink plaster to hold it in place. Led is soldered. Tail is finished.
It turned out longer than I was expecting but at least it can take protected cells as well as tail stand. The UI of this driver (FX-35) is not so good (H-L-S), if it was just H-L I would be happy with that.
Quick beam shot with the phone. Sorry I didn’t notice the reflection of light in the glass door until I looked on the pc. It has a smaller spill and hotspot than the E14 and AT40
E14
AT40
The only thing left is a pocket clip. I found one on hand but I’m not sure if this one will be strong enough for a light this size.
