Hello fellows! I'm new here as you can see. I am currently in the middle of making my first piece of furniture. It is an aquarium cabinet. I've designed it to be way more sturdy than it needs to be but that is how it goes with first tries - covering all the basis along with overdoing it. The tank is an odd 40 gallon so the weight is not little on the top. I have the cabinet longer than the aquarium because the space the cabinet is going to be filling has to be somewhat flush. Eitherway I have already cut the supporting structure and I can't continue with the sides, bottom, top and door pannels because as I was designing the thing I figured they would be from poplar plywood. Thing is my local store has no plywood whatsoever and I would like to avoid shipping if possible. As I understand it glass aquariums( the aquarium is rimless glass) can be supported only on their edges whereas acrylic has to have a solid surface to sit on. Seeing as I'm building a longer cabinet than the aquarium I figure I have to have a top so with plywood out of the way I am thinking of gluing a poplar/pine top. My issue here is warping during the different seasons. I don't know how bad is it going to be. Maybe if the top is glued with narrow boards so their individual warping won't have a severe influence on the tank. Ofcourse I would put styrofoam under the tank anyway. I would realy apreciate your help!
