Like, dog sharks? lol

I've drilled acrylic before, super easy as you said. But I drilled a quarter inch hole with a solid hole drilling bit.

Drilling a hole for a 1 inch bulkhead or so would require a spade bit, which I have, but not sure about drilling through 1/2" with it.

Anyone have experience drilling that thick of acrylic with a spade bit?

I have a few diamond hole saw bits. I thought they were only good for drilling glass.

Try drilling on a 1" acrylic sheet first for practice. You can buy cheap scraps from a glass shop or here on AA. theres one guy selling acrylic and giving away scraps. You'd Lao need a 1" piece to cover the scratch because 1/2" is too small to hold the weight since it's on the bottom.

Thanks guys. The back compartment of this is pretty cool.. it is actually like a sump. The right side has the overflow box which flows to the middle (currently filled with bioballs) and then flows to the right where there are exit holes.

Pretty cool setup, but I think I will drill it instead. It's only about 4" deep.. can't hide equipment in there. I would take out the compartments but I don't want to risk breaking the tank.

I think two 1" bulkhead holes would be enough flow, right?

@ibrahim, you really think so? The scratch isn't deep, but I can get my fingernail in it. I was being overly cautious by suggesting fitting it over with 1/2" acrylic. You think I should go 1 inch?

I'd do it because it's a scratch on the bottom so that's holding over a ton in water weight. And you need an inch since that's how much is needed to support 300 gallons but if it was a scratch on the side that was 10" down from the top of the tank it'd be about 55g of water, you'd need 1/4" of acrylic because that's how thick it needs to be to support a 55 gallons. srry for my rant but do you get what I'm trying to say? Oh and how long and wide is the scratch? And here is the link to thread for acrylic: http://www.aquariumadvice.com/forums...ic-177114.html

So i started building the stand.

I should start a build thread but I'm not committed to this build yet because the floor would have to be reinforced, it would cost a lot of money, and not everyone in the household is 100% on board with the project (this is the big one lol).

But still, building things is fun and should i decide to flip it, I could get more with tank + stand.

I am copying mr_x's stand design. 2x4 frame, double 2x4 legs. Got most of it done but ran out of lumber and nails on the legs.

How hard is it to drill acrylic? Easier than glass? I didn't have any luck with glass.

Luckily I'll have a long time to figure it out. Seriously going to resist the temptation and store this one until I am ready.
You usually only pay like 15-20 a hole to et acrylic drilled. What's costs is buying bulkheads.
