RocketEngineer and other experts,
I'm planning a 24x24x12 rimless shallow cube with 1/2" glass. Bottom will not have plastic trim. Had a 58 gal tank spring a leak in my living room, so wife requires this tank to have no chance of leaking on the floor.
Plans are for stand to be 30 x 31.5, so there will be 3" extra on sides and front of tank and 4.5" extra in back of tank (for plumbing). Bottom frame of of stand will be 2x8 lumber with plywood on bottom and all sealed so the stand will hold ~25 gal of water in event of leak.
Attached are a couple of pics of a structure I was thinking of using. Front side legs (yellow) are 2x6 and rear side legs (orange) are 2x8. This allows a second set of top rails in the front and back (red) that will support the tank and can rest 1" onto the legs. Side rails (beige) would be notched to allow red supports to rest on legs. A second set of side rails (gray) would be attached to the red supports with hangers.
The top will have a sheet of 3/4" plywood with a drainage hole to allow any water that could leak from the tank to drain into the bottom of the stand. The stand will be skinned in 3/4" plywood that is slightly higher than the top of the stand so that water drains into stand rather than going over the edge of the top of the stand.
Will this structure provide enough support having only the front and back rails supported by the legs?
With this size tank, do I even need to worry about the rails under the tank being supported by the legs? Could I just do all 2x4 legs and then use hangers to mount the internal cross rails with the 3/4" plywood on top? I was even thinking of doing a double layer of 3/4" plywood glued together to have a 1.5" thick top, if needed.
Thanks,
Ron
