I'm building an aquarium stand, with only wood and screws. I'm only equipped with a miter saw, a drill, and some hand powered saws and a leveler- this will be my first woodworking project. The goal is to have a stand that will hold a 35-40 gallon aquarium that will weigh at most 500lbs. But I am hoping this stand could hold 900-1000 lbs. (If I were to sell this, it's footprint is able to hold 75-gallon aquarium)
On the interior corners, it will have a 2x4 that spans top to bottom (30in) that the other pieces will screw into. I can use 2x4's and 2x6's for the other lengths as well, but I was hoping to use 1-inch thick common board to keep the weight of the stand down.
The finished product would have 1/4in plywood on all sides and 1/2 on the top. I was also planning on adding two handles on each end (drilled into the internal 2x4) for ease of transport.
So here are the bulk of my concerns.
Would using 2x4's and 2x6's instead of 1x4's and 1x6's be a better choice ultimately?
Would this design be able to take lateral pressure?
What alterations should I make to make it safe for 1000lbs?
Will the center piece (The one drawn in dashes) on the face and back be of any benefit? Or can it be left out entirely?
Should I use 1/2inch plywood on all sides instead?
The footprint of my aquarium is smaller than the stand, so it's edges won't be lined up with the frame, is that still safe? Aquarium is 36x15in and stand is 38x20in
The picture isn't entirely to scale, but it's close enough to get the point across.
Edit Updated Design - Forgot to add the two "joists" to the top and bottom.
