Does anyone know where I can get a 4X8 by 1/8" acrylic mirror that isn't going to cost me $200-300?

Thx.

I'm guessing you want acrylic so it can't break as easily as glass? If not, lemme know your application. I've worked with acrylic dealers when I was a sign fabricator, I still have contacts and I might be able to help.

I'll check on your specs, see what I can dig up.

Big thanks Nemo,

I am a fish out of water when it comes to this stuff. I guess Acrylic is easier to handle.

Is it cheaper or more expensive than glass mirror.

This is for a projector screen btw...

The end application will be a 84X47 for a 96" diagonal 16:9 with a zoom of 1.5

Mirror coating for a projector screen? Maybe I'm not understanding.

You would still paint over it... Check out the Silver Fire paint thread at AVSForum.

From what I gather even with a paint application some light is going to illuminate through. The mirrored back is to reflect it all back. They say the the blacks are blacker and whites are whiter with flesh tones suffering a tad.

Ok, just wanna make sure you're asking for the right thing.

E-mailed my old boss, I'll see what I can do. What state are you in? I'll probably try to arrange a drop ship if the price is right for you.

How much better is this DIY going to be over something like a Focupix? Even their fixed frames with black velvet are less than the price you've stated for the acrylic? Ok, maybe not quite at the size you're talking about, but still affordable. Actually, the same width, but in scope, is $260.

Also consider that selling a Focupix will be much easier than selling a DIY acrylic. Well, something to chew on.

I guess the Silver Fire paint application with the mirrored substrate is supposed to be jaw dropping.

How does the Focupix compare with Fire Hawk or Carada?

Neat! :)

I think the build quality is not quite as nice as Carada, I am unfamiliar with Fire Hawk, but even BMX gives Focupix the thumbs up, saying it's well worth the money, seems too good to be true, and yet it's still true. He posts several times in this thread, basically about Good Pj + bad screen, versus ok Pj + good screen:

I see that you've posted in that thread too, heh.

Stewart Filmscreens are not to be touched. At 5 to 10 times the price, it's a darn good thing that they do make some very solid material that is excellent.

The Focupix screen material isn't quite as robust as the Carada Brilliant White and the velvet that lines the frame isn't as durable or as securely mounted as the Carada, Stewart, DaLite, or Draper screens.

But, the screen can be broken down, moved easily, and once mounted you will be darned if you can actually tell the difference between a Carada, DaLite, Draper, or the $300 Focupix.

Considering I typically sell Carada and make a few bucks on their stuff, it was hard for me to try the Focupix, but I was suprised at how nice it was overall.

The material looks good, the build quality is decent, but not as solid as others, yet just requires a bit more care during assembly. Once on the wall, it is indistinguishable from most other manufacturers.

The biggest issue I have with DIY solutions is that people spend hours or days, or more making the screen, then completely ignore making a deep black velvet lined frame. They spend $100 (or more) making just the screen, and miss one of the most important parts. Then are suprised that with the cost of velvet, and the time involved, that making a great velvet lined frame can cost $100 and take 8+ hours on it's own.

I've done DIY - and I was VERY happy with the results, but Focupix produced a product equally as good as DIY in final quality, and it allows for me to break down the screen and move it easier if necessary, or perhaps replace pieces if something gets damaged.

My biggest issue with most cheaper screen manufacturers, including Carada, is that they don't have a positive gain grey screen. Firehawk, High Contrast Cinema Vision, etc. A 1.1 to 1.3 gain grey screen from Focupix and Carada would be a phenomenal asset.

It is interesting that you touched on the 'positive gain grey screen' I believe that is one of the thoughts behind the Silver Fire paint application.

Time I have, Money I have. DIY I want. I've seen some screen shots of the SF on a treated acrylic mirror and it looked like a plasma (with some ambient light in the room).

I am now shaking all the trees that I can for a substrate that will be ~$100 mark plus another $60 in paint. I don't mind throwing some time into it.

Could you look over the calculus that will be my PJ setup: I left ~10% wiffle room with respect to zoom.

I don't want to sacrifice any lumen output with this PJ since it isn't exactly a light cannon.

jinjuku, first the good news.

I way undercut the price you're thinking, by almost half.

Bad news, it's for a minimum order of 100 pcs. The manufacturer that supplies the vendor only sells in this minimum quantity, and mirror faced acrylic isn't used in signage so they wouldn't normally order it. They'd do it for us at cost, but only if we agreed to buy the whole order, bringing your screen to $6500.

We're still looking at the other suppliers to see if any of them stock it regularly so we can just pick up from their available sheets. Hope to have something soon.

Gonna read that thread you posted. Substrates I know, maybe there's something else we could look for that serves the same purpose and is more readily available.

I have emails out to several local plastic supply houses.

The $220 that I was quoted was just an insult... I don't mind anyone making a profit (that is what they are in business for) but to charge me that for something that is most likely ~$85 their cost is wrong.

$220 is BS. It's really gonna be a matter of finding a supplier that's not looking to net a 100% margin, cuz the cost isn't nearly high enough to justify a $200+ market price. $100-120/sheet is more than fair for a small order like 2 sheets.

No update? I can't beat that price shipped to you, and the shipping sucks since it's a flat pack 8ft long.

General Rubber Supply in Louisville has it for $144/sheet and they will cut it to length. So I am good to go...

Thanks again for trying to source it for me. The $144 seems to be the going rate. So all in all I am happy. I will keep everyone updated.
