Hey Mississippi man. I'm just about to start making my projection screen, but I happened to notice something in the pictures in this thread. I'm not sure if the frame is using 2x4, 1x4 or what, but my question is this: I've seen some people make their screens with the border being more flat, meaning, the 4 inch is laying flat as opposed to the 1 or 2 inch side. Is there any particular reason why one would choose one way over the other?
Also, if the MDF that you suggest is 3.25 inches wide, this would of course mean that the velvet wrapped border would not be flush with the frame if the front of the frame is only 1 inch wide, correct? The part of MDF that sinks down (I know not the correct terminology, but the part where it is thinner) will extend towards the inside of the frame and the thicker part of the MDF will be flush with the frame? Maybe this doesn't make sense when I type it, but it makes total sense in my head.
I guess what I'm trying to say is that the dimensions of the border and the frame are not equal, so what should the layout be when you nail in the MDF to the frame? Just want to make sure I'm getting this correct. Thanks!!
