Earlier I mentioned the stand will be on wheels. This was not my preference, but I knew the tank would need to move a various times for various reasons. I can move the tank in any direction, front to back or side to side without having to break down the entire tank. For this, I used low profile wheels, rated at 300 pounds each.
The stand floor was built with two layers of plywood for added support for the wheels.
Finishing the last stand doors with European frameless cabinet hinges.
I was concerned about carrying the weight across the front. For this, I made a wood beam, made out of two layers of plywood, glued and screwed together. I added a center post to over engineer it. Its not needed; its a security blanket.
This is the final cabinet with the pieces assembled, including the equipment tray. 3/4" plywood was the only material used, besides the hardware. I will add a toe kick between the wheels in the front and sides to finish it off.
