Good to see you on the forum damsam77,

You may still be able to go curved, check out tr6's screen build. His screen is flat in the back and is against a flat wall. He cut a curve out of the front of 2x5 material. Perhaps this may be an option for you.

I know you've been working hard, but we need to see some updates on your thread along with some pictorial eye candy...

If you like the screen check out the star panel which I installed last week. Posted shots of it on my build thread . It's bumped a page since then so FYI it's on page 12.

That is screen track that is used to enclose a 3 season porch or sunroom. Technically the phifer sheerweave material is screen material as well, so I figured it was worth a shot. It worked out great. Here is a Lowes link which shows some pics of it a little further down the page.

Hey Shawn, thanks for stopping by. I am definately pleased with how it turned out. A little nerve wracking going into to it, but once it all came together it paid off in spades.

It's part of the build thread, I just wanted to post over here as well since I got some of my ideas from a few different folks who showed their screen builds over here. Also since it's the 2:35 DIY section I wanted to have some contribution for others to follow if need be that wouldn't necessarily visit my build thread.

So, through my studies on AVS I have been convinced to do a 2:35 screen...but tell me why I would go with a curved screen? I haven't found much on that. What is the benefit...what circumstances should I do it under? Thanks! Looks like it turned out nice!

I'm not Oman, but the curved screen is mainly to counteract the distortion from an anamorphic lens. But it also is a more "immersive movie experience". And it sure looks cool!

Shawn is spot on. If you plan on zooming then you wont need or really want a curved screen as it will create the opposite effect called barrel distortion.

When using an anamorphic lens instead of zooming it can produce the pincushion effect which can be corrected with a curved screen or by having a long enough throw (typically 2x throw or more).

Here's a link with a good pic of the effect.

oman321, great job on the screen. It looks very professional.
I was looking for something not to involved and I don't want to a pay hafty price for a curved screen as all of my budget just went into my HT build.

I have thought about doing a curved screen many times but the attaching the screen material was the part I wasn't to sure about . However, the system you used seem very simple.

I do have just one question regarding the screen attachement if don't mind me asking.

What size Phifer spline did you use .125, .140 or .175 to go into the 1.5" screen tight?

BTW, I will most likely be making 2.37 130" diag AT screen.

Thanks,

Taz

Hi there Taz1,

Thanks for the compliment, building my screen turned out to be one of the best and most rewarding projects that I conquered in my build. Sometimes I just sit there staring at the screen. My wife thinks I should start a screen company I told her they've beat me to it

I can't quite remember which thickness of spline I chose. I can check to see if I still have some at home and report back to you, but I can quickly explain the scientific method I used when choosing it...

While at the store, I got the screen track and picked a couple of spline bags. Without opening the bags I grabbed a piece of the spline and simply pushed it into the track. I went with the one the started to feel like it snuggly fit but didn't require an extra amount of force to get in.

This paid off as the screen material is obviously thicker than the plastic bag. At first I was struggling a bit to get the screen material and spline in, but once you get going with and get used to it, it became pretty easy. I also had plenty of spline so I used several short pieces to secure the screen all around and then I was able to spline one continous piece all around.

Definately read the beginning of the thread for what I would have done differently when it came to attaching the velvet.

I wil still try to see what thickness of spline I used, but feel free to ask whatever questions you may have, I am more than happy to help out.

I found the rest of my spline Taz, unfortunately it's wrapped on something and I don't have the original bag to give you the exact size.

Nice build!

I've been wondering for a long time, do you need some kind of special lens to get the picture right on a curved screen?

Thanks,

You only want to use a curved screen when you are in fact using an anamorphic lens. Wether DIY or purchased from one of the popular vendors anamorphic lens' tend to introduce pincushion. A curved screen corrects this effect. If you are zooming to achieve scope or 2:35 then you want a flat screen.

Why go with a curved screen as opposed to a flat screen?

It is what some folks will to mainly use to stretch their image from left to right. With movies that have black above and below the image your projector or external device such as a scaler, a PC or even a DVD or Blu Ray player are used to apply the vertical stretch to get rid of the black bars. This will then fill your cinemascope screen which can be a ratio between 2:35 and 2:40.

Here is a link to one of the popular lens sellers which has a nice video explaining cinemascope and Costant Image Height (CIH).

It looks like your project came off with exceptional results! Thanks for all the details. I kept looking for pointers on how to make a curve screen. Thanks to your tips, I'm going to give it a try.

The construction looks straight forward. My next step is to select screen material. I'm debating going acousticly transparent versus material that is digital ready (in case I get rich and go 3D). I have the sample pack from day-light but am not familar with the material you used. I'm sure I can find a link in here to guide me through the selection. Again, congrats on a great project, and thanks for sharing the tips with the rest of us.

Thanks Saask, the material I used is Phifer Sheerweave 4500 which could be easily had from this online vendeor.

http://www.interiormall.com/cat/nsam...=113044&t=2182

If I were making my screen today I would use SeymourAV.com next generation sheerweave material center stage XD for a comprable price and since he is willing to sell to the diy'ers. Good Luck.

Welcome Digesh71, It really depends on what you pland to do. First of all I'm assuming you want a scope (2:35) screen. Then the question is are you using an anamorphic lens with vertical stretch or are you zooming the image to get rid of the black bars.

If you are using a lens you would want to go with a curved screen, if you are zooming you want a flat screen.
