Hi! I've been a member here since 2005 and getting back into the hobby. Started my journey, back in the day with Surefire incandescents. I was lucky to pick up a Hanko Machine Works flashlight. I also picked up a Hank Emissar D4V2 last year. I saw in this review, https://zeroair.org/2020/09/04/hanko-machine-works-total-tesseract-trident/ that the light engines are simply screwed in. I wanted to start creating one, as I'm familiar with soldering, but have no clue as to where to get the copper pill that threads inside the head. Does anyone know where to source these? I believe I can pick up the LEDs, boards, and lens from Hank's website. Does anyone see any issues I may have missed once I have the copper pill to set everything in? Seems like a pretty easy build to me and an awesome way to make several engines for beautifully built custom lights! Thanks in advance for your help on this.
