Bulding an Aluminum Framed AT Screen - Page 2

post #31 of 52
Maybe once its on the stand, the stand could help hold it still as you try to stretch it more. Also, maybe go from top to bottom pulling on it, or start at a corner and work your way out, that should get it even.

I am going to try it out on the floor again first with someone to apply counterforce to the frame. I may try to follow the pattern put out on the Seymour website for the wood frame and staples. It is close enough now that it would not be noticeable while watching a movie, but you can see it around the edges in the light.

I have tried everything you wrote except putting it on a stand and it has worked pretty well. There are very few wrinkles remaining.



I was going to build a stand like the one below, but. I am going to build stand that will hold my speakers and then hang the screen off the front using a french cleat. Once it is up there I will attempt to stretch it a little more.

I will upload plans soon.

Here are the plans for the new stand:



And here is a mock up with speakers and acoustic panels:



I hope that I can get it done today.

Looks a million times better! The stand looks good, I did something similar when building mine. Keep us updated!

You were right. Once I got the screen on the stand, I was able to stretch the wrinkles out.

I will post pictures in a little while.

Sweet! Yeah lets see it! BTW, you're gonna love the screen.

I am hopeful that with a little more tweaking I can get the last few wrinkles out and the screen will be fine so I will get away with the Velcro.

It is pretty close now, but I still need to build the stand to put it on. We will see if there is enough time on Sunday or Monday.

If you want it tight then spline it to the frame. You can use dowels directly to the frame that you have or you can attach "screen Tight" to the front of the frame and spline the XD material to the "screen tight" I used "screen tight" to attach my screen. With the screen mounted on the front side, then you can hang a velvet covered wood frame on the aluminum frame. This way the velvet covered frame is tight to the screen, so that there is no shadow.

Thank you. Your thread was what inspired me to try the aluminum frame. I was able to get all the wrinkles out with the Velcro so I will leave it alone for now.

I am planning on doing a velvet covered wood frame at some point, but I am not using the whole 115 inches right now since that really overpowers the room, so I will wait on the frame for awhile.

Sean,

Here are the pictures:

New front stage.



Here it is with the screen installed.



You are right. I love the screen.

I have recalibrated the audio, but I have not got around to getting the colorimeter out to calibrate color for the new screen. Even uncalibrated, the picture is awesome. It is great having the sound come from the screen.

I couldn't agree with you more! Its something that is under-rated and overlooked by so many, its a shame really. It looks nice how tight you were able to make it, now once you add a border to it, the image will even pop more.

The adhesive on the Velcro started failing in the summer heat in the garage, so I took it off and reattached it using grommets and o-rings as you detailed on your thread. It worked great. The screen is much tighter and looks a lot better. Thank you for your post, and thanks to Chris Seymour for giving me information on grommet spacing. I will post pictures soon.

Here is a picture of the screen after I reattached it using grommets and o-rings.



I did it basically exactly as written in this post:

http://www.avsforum.com/avs-vb/showt...1#post17212501

I spaced the grommets 4 3/4" apart and centered them 5/8" from the edge of the material.

The distance from the center of the grommet to the center of the screw attachment point for the o-ring is 2 1/8".

I used 80/20 economy T nuts and 1/4" x 3/4" hex machine screws for the attachment points.

I still need to add a velvet covered border at some point.

I have some speaker grill cloth coming in the mail that I will be hanging behind the screen to minimize reflections off of the metal grills of my speakers which are only apparent when there are a few bright areas in an otherwise dark screen.

My system is pretty much exactly how I want it right now. The whole family is enjoying watching movies and playing Lego Rock Band.

Can you post a close up picture that shows the frame, screws, o-rings, grommets? Having a hard time visualizing the angles. Thanks.

By the way I just checked out your new HT thread. That looks awesome! I would really like to do something like that next year when I finish residency.

I took the screen down to put up some black backing. It is just black grill cloth which should be pretty acoustically transparent. However, as you can see in the picture, it is not very opaque. I will see if it does anything to improve the reflections from behind the screen when I watch a movie tonight. If not, I am only out $20 for 3 yards of material.




While I had the screen down I took a couple pictures of the back of the screen to better show how it is mounted.

The grill cloth seems to have done the trick. The distracting reflections are gone. I am very happy with the picture.

Belated thanks! I'm studying screen frames again. Did you end up using the two types of angle brackets as mentioned early in the thread, or something simpler? I'm thinking just angle brackets or gussets would be enough, as long as they're tight. Any issues with the lack of center bracing? I'm planning a somewhat larger screen, and wondering whether I'd be able to get away without them too. Anything to keep the costs down.

Brad I just updated my build thread with what I used for my frame. I pretty much copied Jedirun's and made changes from his experience. I am currently working on the velvet border to hide the frame.

I just used angle brackets by themselves. They are sturdy enough.

The only issue with the lack of center bracing is that the top and bottom pieces are very slightly bowed inward from the tension of the screen. If I had to do it again I would go with 1x3 pieces rather than 1x2 pieces.

It is only noticable if you are looking for it and it does not effect the tension on the screen at all.

Sorry for posting in an old thread, but I am looking to do something very similar and was curious about how folks went about attaching a velvet border to something like this?
