Post 2nd DIY 153" Frame with Spandex

Ok,

While it's really tempting to buy the Silver Ticket 138 or 158, I think it might be time to build my 2nd DIY screen with spandex. Using the customer screen size tool at Draper, I have come up with the following dimensions for a 2.35:1 Scope screen. Please double check my math/plan. Most of my viewing will be movies in widescreen, and using my JVC RS500's zoom to watch 16:9 content.

Format Height X Width = Diag
2.35:1 60" X 141" = 153.25"

Zoomed down for 16:9 content

Format Height X Width = Diag
16:9 60" X 106.625" = 122.375"

Materials Lists:
1X4 Grade A Pine for base frame
1x1 Grade A Pine for spandex standoff
ScreenTight
Screen Spline
Kregg Jig/Pocket Holes
Couple of metal hanging straps for added strength
HD Flat Black latex paint

JoAnne's White Spandex
JoAnne's Dark Gray/Silver Spandex

Switch to Poplar on the Frame.

Use Quarter Round for Stand-Off. 1" x 1" is overkill and not likely to be straight.

Progress Update

Ok, I found some time to throw together the frame this weekend and temporarily stretch the white spandex over it to see if I liked 153". I already had the grade A pine, so to save money didn't go with the poplar and decided on an edgeless design. (thanks for input MM) Top/Bottoms are 141" wide made of two (2) 70.5" and the up rights are all 58.5". The two middles are for center support and installed at 40" from the ends. Here's some pics of frame, and some images of playing around with the lens memories. 1 Kylo Ren in 2.35:1 and 1 of King Bob in 16:9.

This coming weekend, I plan to install the screen tight and stretch the silver and white spandex and install some french cleats. I'm hoping the surround frames/fabric will hide the screen tight, and end up looking like a flush wall. More to come.....

Screen Tight and Stretched

Finally stopped watching the temp screen and have made some more progress on the screen. I added some 1x4's between the 2 center supports and some simpson metal ties across the center joint to strengthen the center section. Since I was adding some braces, I also added some corner braces to the already glued/screwed corners. Bonus, the new 1/4s also add some nice places to attach a french cleat.

Since I built a box instead of flat frame, I installed the screen tight on the outside edge towards the back of the frame and smoothed the edges/corners with some sandpaper so the spandex didn't snag. So that I had some working room to stretch the spandex, I elevated the frame a little. First layer of gray spandex stretched and clamped while my daughter and I installed the spline rolled in the first channel. Then the white spandex was stretched and clamped, and more spline in the second channel. Time to stretch the spandex and secure in the screen tight was about an hour.

I choose not to paint the frame yet, as this is temp round 2. I still need to frame football posts, and build the surround frames. Once that's done, I'm going to do 1 round of painting and re-stretch the spandex since it doesn't take much effort.

Here's a drawing of my concepts for the box frame, screen tight and surround frames. I think by building the surround frames out of 1x2's I will be able to fit them against the screen frame without affecting the spandex. Thoughts?

I like it!

Your Box frame idea is wholly viable, as I have done similar before. Get'er dun!
