I stopped by the local glass shop to get the particulars on ordering tempered glass. They said that all they needed to know were the dimensions and thickness and they would order it. Asked about not having it marked tempered and they said no problem. Takes about 10 days to two weeks and OBTW the minimum is $27. Is this typical? How much have others paid?

I payed like $23 bucks from tendayglass.com

I Got Mine locally here Gave them the dim. 12"x10" and paid $14.00 that was about 2:00pm, They had it ready the next day after 12:00 pm. Said they just had to put it in the furness and fire it up.....

My tempered glass was $16.50, I also ordered two peices of double strength non-tempered glass for the fresnels. It took them 3 days to get the tempered glass order in. However I didn't ask for it to not be stamped so it was. Hardly noticable.
The total order came out to be $23 and some change. I got my galss from a place called Okolona Glass. If I were you, I would get out the yellow and start calling glass and/or framing businesses and getting quotes. 12X10 is the size I got because it was just bigger than the fresnels and very easy to measure .

So I guess I should look a little further a field. One of the few downsides of living in rural Iowa.

My local glass place says if I wait till they have another order going in it will be $20 Cdn.

havent ordered yet but was told $25 by the glass company..

$15

$15

I got 10 peices for 90$CAD

paid 25 for mine locally. Was ready the next day at noon, ordered it at 5:00 p.m. the day before.

This is where I got my glass too, cheapest place I could find in the Louisville, KY area. If anyone else on here is in the Southern Indiana/Louisville area, I would go there.

I got three pieces for about 20 bucks.

$13.00 locally Anaheim, California.
they dont ship

15 bux

$16 that includes 7% tax

I read in the guide that you are supposed to get your lense cut a 1/2" smaller (in height) than you box dimensions to allow for the cooling circuit. With the box dimensions that the guide gave, that means that the tempered glass would be a 1/8" thick and 10 1/2" X 15 1/8". Is this large enough to cover the fresnel lens and protect them?

Also, I called the local glass store and got a quote... $45!!! Is there a cheap and relatively quick place online to order tempered glass that anyone recommends?

Actually the glass would be around 9 3/4" x 13". The measurements in the guide are outside with 3/4" mdf. Inside measurements would be 10 1/4" x 13 5/8". Allow yourself some room on the sides of the glass as you will only need 12" of fov to get to the condenser fresnel. You want 1/2" space for air to pass under the fresnel for cooling.

Hey, where about in Canada are you ?

I am in the planning stage of my PJ, but I would not mind ordering with you if it means getting a deal.

I am located in the Greater Toronto Area.

Let me know

My bad man. I forgot to subtract from the width and the guide confused me because it said to take only 3/4" off the overal dimensions, instead of 1 1/2" (from both sides). Anyway, any place online where I can get it cheap? Where did you folks get it for $15? Locally?

hi, ive been in 5 different places in NYC area, and is about $60, one of the guys said, "its very, very expensive!!!"

i didnt want to order it online, 'cause I didnt wanna wait!

so its either putting some regular glass in the Microwave or going for the OneDayGlass.com thing!

cheers!

$10.62 in Salt Lake City

9 3/8" x 12 something" x 1/8"

Company name: Glass Unlimited

(Yep...tempered)

This was a tiny little window/glass shop in the middle of a major area of industry. Found it in the internet yellow pages.

I called about 30 glass places within 10 miles of my house and the lowest quote I got was $20. I found out later that they had to charge me $5 extra for not stamping it, what a rip off, but it was still the cheapest at $25.

Well.... I tripped across something today while digging around for a cheap tempered glass solution.

Problems:

#1 -- Standard Sizes are 10"x10", 12"x12", 14"x14", and 16"x16" -- as we know Tempered Glass cannot be cut, and the plans call for a different size. But, check out Toblerone's solution to using a piece of non-custom glass for isolation.

#2 -- Thickness is 3/16", a little thicker than the 1/8" spec'ed.

#3 -- You gotta by them 10 at a time.


Positives:

#1 -- Cost for the 10"x10" and 12"x12" is $2.20 per panel. ($22.00 for 10)


There may be other sources, (in fact, there are -- I did some more digging) perhaps even local ones. These panels are "standard" because they are used to construct "Glass Cube Shelves" for store displays.

Thought I would throw it out there, maybe Brain or someone can do a group buy and offer them one at a time in the store or something...

Link to the place I originally found them:

3/16" Glass Panels from The Fixture Zone -- Click Here

Do a Google for "Glass Cube Shelves" and you will find a ton of other places.

Hope this helps on cutting down the materials cost for some people!

DrudgeMart - i have a piece of tempered glass cut to my specific size - i forget the measurements but its a rectangle -


onedayglass.com

does it -


One the other note it is possible to cut tempered glass with one of those cheap glass cutters - I have done this when I built my boa cage - its a pain in the butt, but it can be done - i had to score both sides of the glass and tap tap tap away - until it cracked -

just go to onedayglass.com and they will hook you up with any deminsion with no stamp.

fyi

neda,

I am from Barrie, Ontario did you order your Temperd glass yet? if you havent orderd yet see if you can get any deal for ordering 2 pcs I will pay you.

Just found another source for tempered glass. Good idea, Drudge Mart, looking for fixture companies. They offer 10 x 12 which is just about perfect. Extremely cheap, too! They refer to the size taking into account connection intersections so I have emailed them to get actual size in relation to specified size.

Nice find -- was striking out on finding 10"x12" pre-fab tempered glass, and it's hard to beat $2.25 usd.

Let me know what the actual dimensions are when they get back to you, if they are undersized, maybe one of the larger ones will be close enough to make work.

Good news and bad news. Glass is cheap, but shipping is $12 "crating" plus UPS. Comes to $21 or $22 dollars per shipment. Crating charge is the same for 1 or 100 so could get cheaper for bulk order. Don't know what I'll do yet

I found a local place that sells these pre-fabbed tempered 10x12 for panels the glass cube shelves for $3 a pop.

Same place I called asking about a "custom" piece and was told $18. Guess I can't blame them for trying to sell me what I asked for, but I think I will opt for saving $15, eh?

~DM~

I've noticed that some are moving the tempered glass nearer the light source. This being the case ,wouldn't the narrower light path allow for a narrower and possibly precut piece of glass?

I found a place locally to sell me the glass at $11.52. They said it would be about a 2 day turnaround, but thats fine as my box isn't ready yet anyways. Atleast I got the hard part done, ordering! haha

How about FREE tempered glass? Glass shelving in refrigerators is tempered. All you need do is trash pick it and cut it. Keep your eyes open
John

Uh.. Don't try to CUT tempered glass. It will shatter on you.

Glass must be cut BEFORE it is tempered.

Reference Modest911's post about his boa cage, nine post's up. He stated he has cut tempered glass.
John

Edited to add...
After reading further, I agree that you can't cut tempered glass. Modet911 you must not have had tempered glass.

Where in Anaheim did you get it? Since I'm in La Mirada, thats just 20 mins away from me.

it was - double pain tempered storm glass that came out of my dads house - but that okay - i know i cut it cause i did shatter a few pieces

I just ran some tests on Lexan, and came to the conclusion that it works very well as a substitute for tempered glass.

It costs $4.73 for a 11"x14" piece at Home Depot. It has the advantage of being cuttable, and shields UV already.

Where in Home Depot did you find it? Also, how is it cut to size? Are there any disadvantages to using it? I ask only because since it is so much cheaper why hasn't everyone been getting Lexan from the start... Thanks for the help!

Obviously, Home Depots may vary in their organization. Ultimately, I had to ask someone in the window section, and they directed me to it.

At my Home Depot, it was in the back wall, between the lumber section and the screen doors. (The lumber section is broken into several subparts; it's the one with the pre-cut, pre-laminated pieces for building bookcases.)

They offered it in multiple pre-cut sizes. If they don't have your size, you can always cut it yourself with a jigsaw (get a blade rated for plastic). Don't bother with the knife cutting tool they recommend (and place near the display); it's too difficult.

People are worried about the plastic melting, catching on fire, yellowing over time, and... hmm, I think that about covers it. People don't have those gut concerns about tempered glass.

I don't believe we have those problems with XL-10 Lexan in this pj. The temperatures don't get hot enough, and the Lexan is treated for UV.

If I am reading the spec sheets correctly, Lexan XL-10 will catch fire if exposed to open flame at 873 degrees F, and will spontaneously combust if it reaches 1,076 degrees F. By that point, you've already shut down your projector and started crying because your LCD is toast.

I also like that it is 250 times stronger than annealed glass, while tempered glass is only 3-4 times stronger than annealed glass.

If the bulb explodes , your optics have greater protection.

Haha, thanks for the help. I can't find any local places that offer decently priced tempered glass custom cut panels (the lowest quote I got was $45!) so this might be a perfect alternative unless I find somewhere on the web that sells tempered glass.

Has anyone used www.onedayglass.com ? If so, what size did you order? I tried using my measurements, but they didn't reach the minimum order amount ($15). Thanks.

I used them, http://www.onedayglass.com/tempered.html and recieved my 12.5x10 piece in less than week 4 buisness days I think .. I called them , and originally planned on sandwiching my lenses .. After some reading here , I don't believe I will .. Anyway , I will probably have 2 left over .. You'll probably see me post them up in the sale section here in the future .. I had good luck with them , but yes , you need to meet the 15 bux they want .. Suggestion : order some typical glass to put on the grooved edge of your fresnels ,( for easy cleaning) along with the tempered .. That should get you the min. order .. Sorry I don't remember the mesurements for those .. I bought those locally , at Ace .. You'll want to have the regular glass the same size as the fresnels.. Good luck. Make sure you call instead of trying the site , if you use them . You're better off , I found out the hard way ..

I finally ordered my tempered from www.abctarget.com--tempered glass link--

Tempered Glass

--minimum order is 4 pieces, but for $23, so what. Will let you know how long it took to receive and the condition it came in. The cube display glass is definately the cheapest way to go compared to a glass shop. These are avail. in 10 x 12 which will work fine. kcglass.com has 10 x 10 and 12 x 12 in single pc quant., but thought the rect. profile would be less problematic. When I get my bulb situation straightened out, I'll be ready to begin.

I have a quick question... all you folks are ordering 12" x 10" tempered glass, but won't that block some of the light? To mount it you need to come in on the sides. Is the light field that wide by then, before it hits the first fresnel lens? I'm just thinking that the LCD is 12" x 9" viewable and I don't want to block light.

I'm mounting the glass by itself, a little further back in the light cone

Brain,

How do you feel about the pre-cut sizes? Will they work?

Thanks,
Andy

Sure, you'll need to pay attention to the cooling circuit. It's also much taller than it needs to be.

I can get a peice of 4mm optic clear tempered glass for $25.00 Australian. Apparently it has less iron in it so is crystal clear 1 week to get it .

Ended up getting the size recommended by you Brain in Tempered glass, found a local place for $15 plus tax. This is probably one of the cheapest places that I have seen from all of your other posts. If there is enough interest maybe we could arrange a group buy and you could sell them at the LL store, Brain?

Also, the shop that I got them from ordered them from somebody else, so I'm assumming that we could get them even cheaper that that.

Andy
