Ok so the metal frame in this picture is seriously bowed. I planned to shim between the plywood and the metal frame to bring the plywood up so that it touches the tank frame.
The problem is that with the tank empty, putting the shims in enough to bring the plywood up to the tank tends to just lift the whole plywood top up and I end up with a plywood top totally proped up on shims not touching the stand anywhere.
There's only two options here and I'm stumped.
Option A - fill the tank part way up with no shims and a visible gap in the middle of the tank then shim under the wood now that the weight of the tank will cause the wood to bend to where it needs to be instead of moving the whole tank.
Option B- just shim between the plywood and the tank so that there are only short areas not making contact.
I'm really stumped and want to leak test this thing tonight!
