Do you have a build thread? Are they easy to do? How expensive?
No build threads. Instructions are on the Seymour website
Here are some tips tho:
-I am a minimalist so I didn't do any of the miter cuts.
-Don't use those metal corner brackets unless you get some super strong ones. They will bend the first time you try to pick up your screen (ask me how I know
). I just put pieces of 1x3's across the corners and they hold perfectly. I have taken down my 200" screen dozens of times alone and really put some stress on it and it has held up wonderfully, a tribute to the strength of the 1x3's, not my carpentry skills.
-If you have the skill and patience use the grommets/rubber bands. I don't have either so used staples on all three.
-I had my first one angle cut. The next 2 were too big to do it but I have never seen any moire in over 4000 hours of viewing. But I have had JVC projectors which are not supposed to be sensitive to it. YMMV.
-Definitely use the triple velvet around the frame, it is awesome. I also use it on my walls and ceiling around my screen. Makes it a black hole when the lites are off. My room has no lite coming in.
They are so cheap to build is one of the reasons I did 3. At less than $150 (at that time) it was easy to go up in size. My 200" cost about $250. I built a new room so went with the max size I could.
Hope this helps.
