I am planning on building a AT screen. I am going to use the Semour AV Center Stage XD material, http://www.seymourav.com/screens.asp
and make a frame using http://www.8020.net/
T-slot aluminum framing.
Here are the plans that I made on Google Sketchup for the frame.
Initially, I will just try to attach the screen material to the aluminum frame. Eventually, I will add the border as shown.
I plan on using the 1.5 inch material for the frame.
The railings come in 12 foot lengths that the distributer cuts to your specifications. They have a wealth of connectors that can be used for corners or to string the railing to gether end to end.
I am going to try this connector: http://www.amazon.com/80-20-4-HOLE-I.../dp/B001IA12YE
I may add this connector: http://www.amazon.com/80-20-5-HOLE-J...943418&sr=1-44
or this connector: http://www.amazon.com/80-20-5-HOLE-D...943418&sr=1-45
for added rigidity. There is a distributer 20 minutes from me so I can get the stuff without worrying about shipping times and costs.
Bosch Rexroth sells a similar system: http://www.boschrexroth-us.com/count.../mge/index.jsp
My hope is that the frame will be rigid enough to avoid the need for a center support, as I understand that the center support may show through on bright scenes. I would also like to attach the screen to the back rather than the front of the frame so that I will have an easier time attaching a border to the front later, so I would need to avoid using a center brace. I wonder, however, if a border would be less effective if there is a gap of 1.5" from the screen to the frame.
If more rigidity is required they sell 1x2" rails and 1.5 x3" rails.
The screen material does not weigh that much but I wonder if the tension will be too much.
I am planning on making a 114" diagonal 16x9 screen. That is about as large as my projector is capable of based on the calculator at http://www.projectorcentral.com/proj...ulator-pro.cfm
It is also just wide enough to fit my Triple 8's behind at their current width, and about as big as I can fit in my tiny room.
It may be that 114" is too much for my room, so I may not use the whole screen, but I will have a pretty big screen for later use in a better room.
I am thinking about going this route to attach the screen, although it looks pretty involved: http://www.avsforum.com/avs-vb/showt...1#post17212501
That would make it pretty easy for me to take this apart and put it up again somewhere else.
The project will probably cost me around $500 for the initial screen without the border. I have not looked into the cost of a border at this point.
The Aluminum framing and hardware should cost around $200 and I think the screen material will be somewhere around $250, the hardware to attach the screen to the frame will probably cost me $50.
Here is a picture of the current front stage.
The current screen is an 8 foot by 6 foot diy screen using rubberized canvas on a 1x2" wood frame. It is a little warped, which is why I am going with Aluminum rather than wood for this project. I am currently projecting a 16x9 94" inch picture on the screen.
I plan on hanging the new screen from the ceiling and moving the speakers up to place them behind it. I will also probably rearrange the acoustic panels, placing them between the speakers and hanging the top panels on the wall to get the screen as close to the front wall as possible so I don't have to move my seating position too far back. Eventually I would like to use this screen as part of a false wall in a dedicated room, rather than in my garage, but that is at least a year away.
Any comments or critiques of the plans are welcome.
Is there anyone who has made a similar frame who can comment on whether they think that I will be ok without a center support?
