I took advantage of the 3 day weekend and worked on my boards. Stupidly I started them in a temporary location rather than the "bench" and scrapped the 1st board with a stupid cutting mistake after I had it already populated.
I have built many things in my lifetime but this project is somehow special and has been a journey in self discovery. I have learned so much about myself. First, I am a very angry man. Second, I am apparently blind now requiring more magnification and light than I thought ever possible. Third, I suffer from some weird form of aphasia that only lets me figure out that what I'm vigilantly checking and double checking is completely backwards when it's impossible to fix. Finally, always go with what you know. I tried several of the new fandangled methods for SMT soldering that seemed less complicated but ultimately what worked is my old methods of doing things that I thought were inferior. Trust your gut. Anyway, I too have some cad/stellated boards on the way to test and have a pretty good process for cutting/shaping the existing ones. I've also determined that hot air is the way to go for assembling these things but still I can only crank out about one an hour. I'm using some solder paste and one of these guys: https://www.amazon.com/WEP-858D-Soldering-Station-Suitable/dp/B0055B6NGE I got some epoxy (to hold the flash on) and plan to try the hot skillet method later this week. If I can do several boards at once I may be willing to both share my setup and help with production of these things if necessary. More to come in the next few days.
