Well, much seems to be on hold at the moment. Don't have the painted closet doors back yet, don't have the next furniture delivery, and don't have any volunteers to help with the wall electronics, but I do finally have all 3 pieces of glass (been waiting since November) so it's now time for an analysis and hopefully some feedback.
I've got 3 different glass types:
A = Concave 7/8" Clear Reed (which is what's professed to be the "correct" reed spacing by Trek "experts")
B = Concave 1" Clear Reed (which in reality is not quite 1")
C = Convex 1" Krystal Textured Flutex (which is the only reeded glass having a texture)
Each piece is oversized by 1" (in hindsight it should have been only 1/2"), and I think the 7/8" reed can be eliminated because it simply has too many "bars" on the glass (space between the reeds). There are 17 bars on the glass (resulting in 16 inside the frame), but screenshots clearly show 12~14 bars with 12 being the most prevalent:
Having selected 6"x12" for my panel's inside dimensions and being there are 12 visible bars on the glass, it makes sense that this would be 1" reeded glass. I've searched and searched, and the largest reed pattern available is 1" but not many places stock it, and even fewer offer shipping or retail sales. Glass B is 1" reed but the spacing is not 1", more like 13/16" resulting in 15 bars (which would yield 14 inside the frame):
Glass C has 13 bars, being the closest to the target 1" spacing since there would be 12 bars inside the frame:
With A eliminated, comparing B and C they each have pros and cons. B is a thinner glass (5/16") and thus weighs significantly less than the much thicker C (3/8" and heavy!), but visually C looks more like what I'm seeing in many screenshots like the ones above.
Next I did a "phaser test" to see which of the two glasses looks more like "The Conscience of the King" scene:
In this experiment B clearly (no pun) wins, confirming the reeds should be concave and not convex. Keep in mind, a red gel filter isn't behind the glass yet which will diffuse it.
Thus, comparing the overall look (and weight, which is important considering how it's to be hung on the wall) B has characteristics in its favor, and in some regards C looks better (despite it weighing like a brick). I'm favoring glass B. Opinions?
