Drilled 1st tank, but....

[cobray]

So I think my first attempt was a success, but on the 2nd hole, the drill bucked and chipped the outer face of the glass.
Wondering if it will eventually crack.
Please see attached pics.
Thanks!

I do not think it will crack, I have done this before. The real issue may be the bulkhead fitting sealing properly.

I agree.

Ahh man what a bummer with glass you just always wonder about leaks

I would silicone that chip and water test the bulkheads. You should also sand the hole and clean up the inside a bit. It looks like you didn't finish the hole.

Sounds good. Thanks for the replies.
I'll clean it up and silicone the bulkhead both sides.

That was my thought. As long as the bulkhead seal covers it you will probably get away with that. You could try filling that with epoxy, but if you can’t get the seal surface flat you may make it worse.
For reference I’ve had professional made tanks with little chips in the edge of the hole before, albeit smaller than that. But like I said, if you can get a seal you’ll be ok.
