Chipped overflow drilling hole

[Moleo]

I chipped the glass when drilling. The gasket for the bulkhead completely covers the chip, and there are no leaks.

Should I be worried about the structural integrity of the glass, or is this okay?

Aquarium is a shallow 75 liter (≈20 gal): 75cm(W) x 40cm(D) x 25cm(H), glass is 6mm optiwhite.

that would not concern me, it should be fine. Just ensure the rubber seal for your bulkhead is secure.

If the chip is on the wet side, you might have to snug the bulkhead a little tighter than you would otherwise to be sure the gasket seals it up. If it's on the dry side it shouldn't be an issue at all.

For you guys drilling holes: don't push the drill, let gravity do the work — otherwise, you'll chip the last layer. :D

Dont push and use tape on other side.

Put a gasket on each side of the glass and you'll be fine :)

^This!

In the way back, I've drilled some standard tanks without much issue or concern, but I'm now looking to drill a newer, rimless tank with low iron glass, and I'll admit, I'm a bit intimidated :rolleyes:

There's tips and tricks for sure, but I just want to add that I think if you use one of these relatively inexpensive, hand-held drill presses, I believe you can get really great results:

I believe you'll minimize much of the chip out at the end of the cut (really, a grind).

I hope that helps :-)
