xxxbadfishxxx,
I would sand down the stand to get it sitting flush. You don't want anything between the tank and the stand as this can cause stress risers and may the tank to leak/fail. Nice work so far!
chrisqueenz,
Are you worried about the weight of the stand or the weight of the full tank? Each of the 2X4 legs (purple pieces in the original template) can take something like 16000 pounds straight down. SO, the main problem becomes how to get the loads from the tank into the legs. The stand will hold much more the most folks realize.
dots,
Who needs a model? Its 4 beams and 4 columns. Very simple model. Sure you can work it up in 3D and make the pretty plots, but since its 10 times easier, I would stick with my good old hand calculations. KISS
nova67,
Not bad. I hope doors are in the works. I like the idea of putting a secondary area to one side of the tank. I will probably use that for a future setup.
rocko918,
If the tank has a plastic frame around the bottom, I would just set it on top of the stand. If there is no frame then most likely the tank manufacturer wants something between the tank and the stand (foam) and I would cover the top with a piece of plywood to create a nice smooth surface.
To everyone else,
If I missed something somewhere, please let me know.
Happy Building.
