I will have a sheet metal angle (wrapped in triple black velvet) fastened to the plywood to extend the masking edge to the screen. Since the mask needs to be 98-1/4" long to match the width of my screen I have biscuit jointed two pieces of plywood together. When complete each mask will be 8" tall x the width of the screen and frame. Going on vacation tomorrow so I will order the velvet right before I head back from vacation.
You've done manually what I've been planning in my automated system for the last 2 years. (It's taken that long for my home theater build to progress).
I designed an extra big screen with automated 4 way masking. Since I'm not a handy man and I didn't want to screw around trying to cobble motors and parts to work, I figured I'd put together 2 professional products: I bought the Carada Masquerade (remote controlled masking) for the top/bottom masking. For the side masking panels, I bought an automated roller panel system from a company named "Goelst." It offers 5 pre-set stopping points for various ARs. The side masking is about to be put up in a week or two.
But I had the same concerns about masking distance to the screen, since the frame of the Carada Masquerade is pretty thick. So I designed so the screen is extra wide. The sides of the screen would always sit behind the edges of the side masks. The inner side masking panel will be beveled/angled inward to get the mask edge riding right over the top/bottom masks, and thus as close to the screen as possible.
In my case I'll have to make that inner side mask out of something as thin as possible which can be bevelled...perhaps aluminum or something.
