Thanks, but this one is just experimental, I'll be perfecting the process over time. At 250°F w/longer warmup period, there likely won't be any internal gas bubbles causing deformation. I've already figured a way to get the mounting ears and surfaces a bit closer to spec with the 1/8" plexi.

This one is just good enough for me to take some fine wet sandpaper or a buffing wheel and rouge to the backside to matte it out. I've been itching to play with the optical setup of the rear projection system for the MacintoshClassicIIIColorTVp™ for a couple of years now.

Once I've learned enough by fine tuning this setup, it's on to bigger and better for the long term ClearProtoHoaxMac™ Project. }:)
