Why you don't drill tempered glass...

[DMBillies]

I've really been wanting to drill a tank lately, not because I need to, but because I think the skill could come in handy in the future. Anyway, looking around a bit on the net I found this video... which pretty clearly illustrates why you better be very sure that you don't try to drill tempered glass.

Wow! That was intense!

Did yours do that, John? I thought you only had a single crack.

Yep, been there done that on a 29 gallon I didn't think was tempered. As I understand it, there is a thin sheet of plastic adhesive vacuum sealed within the glass. When you break the vacuum, and release the tension the glass shatters. The sheet is there to hold the glass shards in case of breakage that's why it does not fly all over the place. Now this information may be totally incorrect but it has kept me from drilling known tempered glass. Losing the 29 gallon has made me leery of drilling all other tanks.

Wayne was really glad the back glass of his 180 was not tempered this past weekend when we drilled it But he was reminded of his old Navy days when he took a "salt water shower" Great weekend Wayne, thanks

and to be also fair , why was the guy even trying this without any method of cooling either.

Ya and ended up getting a new cell phone as I had it in my front pocket when Norman sprayed me . For some reason the water indicator didn't change so it was covered under warranty.

I really don't think it matters how you cool it if it is tempered you won't like the results.

yea brandon...mine shattered just like that....his didnt crumble to the ground like mine though...you'll hear a big "POP"...and its all over

Yeah, not cooling is not a good idea either... so they are definitely not to fast on the uptake.

That was our experience. We were cooling diligently and the results were quite negative.
