So my old projector (Benq W5000) died and I ended up buying an Optoma HD3300. I love it, but in order for it to fit my fixed (read: borders glued to the wall) DIY screen, I had to move the projector closer to the screen. I am currently using an anamorphic research lens with the CA fix. What I am getting now is a much more noticeable pincushion distortion than before (I'm at around 1.8 throw ratio). Also, I realize that a curved screen will most likely not fix the softening at the edges, but perhaps it may make it a little bit better? At any rate, I'm also hoping to make a curved screen that is moveable, acoustically transparent and, if possible, uses a weave that is 4k projection friendly.
I have used Aussie Bob's spreadsheet, so I know the curvature that is needed. What I need help with is how in the world to build this thing. I have a buddy that is a welder but he is far too busy, so it looks like I'm stuck with using wood. Can anyone who has built a curved screen using fabric let me know how they went about doing it? I'm a visual learner, so any pics would be much appreciated. Oh, and if anyone knows of an AT fabric that I could purchase that is 4k friendly, that would be awesome. I had a bookmark for a company that sold DIY fabric, but I had to reformat my computer and my brain just doesn't remember stuff like it used to...
Thanks in advance for the advice/help.
PS. The thing that is weird is that my DIY screen is 2.37:1 and my Benq fit it perfectly, but now with my Optoma in order for the sides to fit in the screen I am getting black bars on the top and bottom. Seems that the anamorphic modes on these two projectors are definitely different.
