I was headed down the staple route but thing I’ll go spline. I already have the Seymor screen but trust it should be the same experience as spandex.
Can I ask, did you have a quideline that you followed on the install or did you wing it?
Looks like I'm as bad for the delayed response. Sorry about that! The theater is looking good!
As for guidelines, there are several ones on the DIY screen guide. I'll see if I can find the ones I used. (and see if I have pics on my theater build, "Darren's No Money No Time" theater
1. Use fingerjointed pine (FJP) 1x4 for the frame of the screen. I'll have to double check the size, but I think that's the size I used. Windsor Plywood has 16' lengths available.
2. Cut the top and side pieces, making sure to subtract the size of the wood from the side pieces (in my case, 3.5" top and bottom, or 7" total.)
3. Cut 2 more pieces for support for the insides. I placed mine equally apart, leaving space in the middle of course for the center channel speaker.
4. Use butt joint for each of the pieces, as mitered/ 45 degree cuts are harder to line up. Screw together with pocket screws (using Kreg pocket jig).
5. Flip over, so the smooth side without the screws is on top. On the outside perimeter of the frame, use 1/4 round all around the frame. That way the screen is held off of the frame so the frame doesnt show through. The vertical edge should line u up with the outer part of the frame, and the round part should be towards the inside of the screen. I used a bit of wood glue and brad nails to hold it.
6. Paint the entire front of the frame black (including the 1/4 round), so it doesnt show through the screen.
7. After it dries, mount the spline frame on the back of the screen frame. I mounted it a bit off of the edge, about 1/2 an inch or so. It cuts well with a hack saw, I found a mitre saw chewed it up.
Mounting the screen:
1. Lay the black spandex down. I used 3 pieces (vertically, overlapping slightly) as I couldn't find wide enough black spandex to order. If you can find the 120 inch wide black spandex it really helps for stretching. Or if your screen is smaller and can easily fit the smaller stuff as 1 piece then that's easier.
2. lay the frame over top of the spandex, eyeballing it approximately centered.
3. Cut lots of pieces of spline, about 8 inches each.
4. Fold some of the spandex over the top, bottom, and sides. Start at the center top, put the spline in the OUTER track/ groove. Tool makes it easier for that. If you use the outer groove/ track for the black, then after the black is trimmed, you can use the inner groove for the white. It gets really tight with 2 layers of spandex (I'm sure there's a joke in there somewhere...
5. The slightly stretch the spandex on the bottom, and put a piece of spline in at the bottom center.
6. Slightly stretch one of the sides, put a piece of spline on the center of the side.
7. Repeat the other side.
8. Slightly stretch the top again on each side of the center piece, add another 8 inch piece of spline to either side.
9. Repeat at the bottom, then the one side, then the other.
10. COntinue until you reach the corner.
11. Inspect your work, should be just slightly snug, not tight (definitely not like a drum). Only tight enough so that it doesnt sag. If it's too tight, remove that area (the benefit of using spline), and redo.
12. Once you're happy with the black, trim the excess black.
13. Repeat with the white. The white layer of spandex is most important to be not too tight, or you'll start getting stretch marks. I did the white layer, then hung the screen up to look for them. Easy to redo it needed because of the spline.
Let me know if you have any questions! I would definitely do another spandex screen again! Not as bright as other materials, but definitely adequate for me (let alone for the price)!
