I'm usually public enemy #1 in these threads, but I have to give props where they're due, and I have to say your Obi TPM is THE most accurate I have ever seen; possibly will see.
As I said earlier, it has been almost a decade since people started working on this saber, and you/Erik are the first one(s) nail it in the true sense of the words. Consequently, you should be remembered for it like how JediVic was remembered for his, along with the valves and whatnot. However, I think Vic was also remembered for the first ever to have a saber made from stainless steel. But concerning accuracy, this is irrelevant, and no other saber I've seen topped his Obi TPM in all these years except yours.
You have my sincere congratulations.
I'm sure I'll have a bunch of questions to ask, but for now, the only detail I'm curious about is the 3/8" rod/plate. You say that this is actually a rod that runs down throughout the entire hilt, holding everything together? This is new to me, as I have never come across this in my reference, though I also haven't come across anything of the contrary either.
I had recently flirted with the idea of one day making a definitive Obi TPM, but with the presentation of yours, this has become quite discouraging. :lol
