lets drill some tempered glass...

[kanankeban]

I know...I know...I was tought not to drill tempered glass. I'm very nervous :smokin: I'm so tempted to try to drill a tempered glass bottom...Please guys stop me...!!!!
Has someone out there actually tryed and have success?

Play some Russian Rullette with an automatic...
The only way you can drill tempered glass is with a laser. Any hole and the whole thing shatters/no strength. It's that simple.

DITTO !! YOU CAN NOT DRILL TEMPERED GLASS!!! Just like Heinrich said, as soon as you start to drill, it will shatter into a million peices.
:blown:

Oooh, if you try it, please video tape it and post the video here! I've never seen that before :)

Cool, what to do as an encore after getting paint on hands and ruining a fish tank? Maybe drive the wrong way down a one-way street? :eek1:

Just drill out the back wall near the bottom of the tank. Only the bottom will be tempered.

Sorry guys to disappoint you the show is off...I went to a Glass Shop where I use to buy glass for my architecture projects...And they told me that I was literally insane If I tought I was getting out of this successfully :D....
But I have to confess that either way I can take out of my mine the urge to try drilling some tempered glass...I want to actually see it breaking apart in million parts...:cool:

[Bill Wann]

try sandblasting the hole , It has wored for me a few times .

[SciGuy2]

Maybe a blowtorch? Or a chisel and really big hammer?

Geologists like hammers. Really, really big hammers. Hammers with sharp points on the ends...

Reminds me that I used to air travel with a large rock pick in my briefcase. I'll probably never get to do that again... I keep thinking what if those passengers that took on the 9/11 hijackers had my rockpick? I'd take a well ballanced Estwing over a box-cutter anyday.

Bill,
I spoke to a guy that does san blasting for living, he told me that the glass will crack as soon he would start to sand blast the tempered glass...
Either way, I´ll try to get a peace of tempered glass and try...

Funny, almost every drilling tempered thread ends up this way. I haven't heard of a single person on the board actually go through with trying it. There is always discussion and several schemes to carry out, but no one actually does it. Keep us posted on the impending disaster.

As I understand it, tempered glass shatters due to the stress from the heat and not so much the stress of cutting/drilling.

What MIGHT work would be to immerse the glass in liquid nitrogen or helium and cut the hole with a CO2 laser. Even if this did work, by the time you have everything set up, you could have paid for a 500 gallon tank, completely set up with filters, livestock and lights.

Tempered glass will shatter because it is made with built in internal stresses. The outside surfaces of the glass were cooled at differenr rates than the inside, setting up an internal tension that provides strength. If you breach the glass, the internal stresses break it.

I used to work in the glass industry and the coolest thing was to take a just formed beer bottle off the line before it could go through the leers. A leer is a furnace that slowly cools the glass down so the stress in the glass has a chance to even out (very simplified). After letting the bottle quickly cool down the outside of the bottle is extremely strong, while the inside of the bottle (slows much slower due to lack of air flow) is a very high stress zone. We then used to take the bottle (bud light bottle for example) and pound nails into boards, throw it down a concrete street, etc. It will not break, it is really neat. BUT, if you were to drop a small piece of anything inside the bottle (high stress side, same as the inside of tempered glass) the thing would explode. It was so cool. Just a fun story I though I would share.

I live in Monterrey, Mexico...Its considered a Steel and Glass City...Vitro is one of the largest glass industries in the world, there product of excelence is tempered glass, so I send a email to its technical department asking a possible way to drill the tempered glass, hope to recieve a answer soon...

i was building a glass display case for something. . . i had a bunch of old storm windows to use. . . . i tried cutting one. . .turned out to be tempered. . . . . it was about 5 months ago, and even after buffing, waxxing my floor, i'm still finding glass in the wierdest places. . . it was EVERYWHERE when it happened. thank god i was wearing my glasses. . . . . kinda cool to see it explode though. .. one minute it was in my hands, the next it was gone, about a million and a half 1/8'' nuggets of glass.

[kanankeban]

wow...cool.......If I decide to do some test, I'll be sure to do it outside home :D and of course with safety glasses:cool:
