So I just received a notification of activity on this thread today (February 28th) and it looks like the last activity was on January 30th....
I think I just need to start checking in here every day since it seems like notifications have been flaky lately.

Going forward I am going to label all of them by pin number; the old "Pin 5 = 2; Pin 3=3" nomenclature harkens back to the 105C/QLITE driver configuration "stars".
I am still working on it. Had to get through the holiday rush...the 17mm is working well in my light, just need to make a few final tweaks then order boards.
Slice smooth, wet sand with 1000 grit, then 2000 grit, then 3000+ grit polishing compound. Really, the polishing probably isn't needed most of the time since the sliced dome is already pretty smooth, but it looks nice when it is super shiny. Obviously when you are doing 2000+ grit cleanliness is super important---any grit can leave much deeper scratches than that.
I don't like to use any chemicals when doing the dedomes; in the past it seemed to affect the phosphor somewhat giving some extra tint shift and unknown longterm longevity. I use only heat (traditional soft domes like XM-L2) or a sharp blade.
