It's not hard to cut out a square hole in plywood. One way is to drill a hole somewhere inside the scribe marks for the hole, then use a sabre saw to make the cut. That is the way I'd suggest for most people. If you know how to make blind cuts with a circular saw and then finish the corners with a hand saw, that is quicker, but I suspect you would find that scarey and you should. It is something you should learn from a pro and never try to figure out on your own. I was at a public aquarium volunteering and they had a bunch of huge wine barrels they wanted to cut in half for displaying water lilies in the atrium. The project was at a standstill. I picked up a circular saw and blind cut them perfectly in minutes while they watched wide eyed. They weren't carpenters, for sure! They had already scribed the barrels with nice clear lines. From my perspective they had already done two thirds of the work. You know, measure twice, cut once.
That should hold your tank quite well.
hey guys...
so i just got a 40 gal breeder from this dude off craigslist. seemed like a pretty decent setup when i first got it. he had the tank drilled in the back for an overflow. when i was moving the tank into my room, i guess the tank girated and split next to the bulk head. on furthur inspection he drilled like a 2 1/2 hole and had only likr a 1 1/2 pipe. i thought maybe that was the reason, but now that i have the new tank on the "stand" he gave me, im starting to think it was the stand.
i lie in a 2 story house, so its never going to be level or stable...right? i put a peice of 3/4 inh ply wood under the stand in hope of making it more sturdy. i shimmed the stand and tank be fore i added water. now that i added the water, rocks, and lives stock, its like a 1/4 off from front to back. if i leave it like this till i build my new stand for like a couple months or so, am i endanger of a bust?
