Thanks, I think… 
Yeah that’s always an issue not having a lathe to make screwed parts, hence the bayonet system and no fancy body designs.
The bezel is siliconed in place and the tail end with JB Weld.
The pill is it’s own unit made from brass tube, 3mm copper sheet and a brass driver ring, all soldered together and pressed into the body. This is made to hold the reflector too.
The new Vapcell 14500 is quite good compared to our other usual 600mAh cells etc.
One of the reasons I made this light was to see how the 7135 driver would perform 
I also ordered some Vapcell 16340 cells but they disappeared en route, all I got was an empty box!
I’ve tested the 14500 with a FET driver too.
