DIY Stand build question - problems?
I am looking at making a DIY stand for a tank I plan to buy. I have already made two ADA style stands for 60cm tanks (60X41X45cm, and 60X30X36cm tanks). One with 3/4" MDF and another with 3/4" plywood.
However, now I want to make a 120cm tank stand and I don;t plan to make it out of just plywood or MDF. I am worried about the weight in a earthquake zone) The problem is I haven't fully decided on which tank I want: 120X60X60cm or 120X45X45 tank. I know for a lot of you, the choice is easy, go big! Problem is, I am in a rented place, and not sure how long I will be here. Standard 120cm tank would be easier to fit in other places compared to the wider one. Weight of either is not a problem as I am in Taiwan where all buildings are made out of concrete and bricks, including floors.
So what I want to do is make the stand and then decide on the tank (Basically I have time now and space to work on the stand (Taiwan holidays coming up so I will be more free from my regular teaching schedule)) If i do it that way, I can have everything ready, order the tank and have it in a couple of weeks at the longest for custom made, and be set.
Attached is the picture of the face I plan. Problem is, if I do it that way, and make it for the 120X60X60 tank with say 2+cm clearance around that tank (the3/4" plywood skin) and then decide to get a 120X45(or55)X45 tank, will there be a structural issue. Meaning that the tank will now be sitting inside the 2X4(2X6) frame, not on it. (ofcourse I will still have a plywood top where the tank sits on and cushion mat), but weight wise the tank will be inside the edges of the 2X4 frame.
Will this be a problem?
