Does it matter if go for the $8 1/2 inch or the $40 3/4 inch each plywood boards for plywood tank building?

Does it matter if I use 2x4s or 4x4s for the strcuture and support of a plywood tank?

If I end up building a plywood I will use strong and long screws and wood glue, so, what else do I need for putting it together?

I would use pond liner to coat the inside, no viewing window.

Dimensions would be about 10ft x 4ft x 4ft.
 
To be honest, I hesitate commenting on this because of the depth, but, IMO, if you are building a frame for external bracing and you build the frame right you can go with a thinner plywood without any issues. I would use 2x8s for the frame and build it much like you would the wall of a house but go 12" OC instead of 16" and I would double up the top and bottom plates. Heck, I might even doulble up the 2x8s. Use deck screws to assemble the frame and to attach the plywood to the inside of the frame. You really dont need glue on this project but you will need 3-4 crossbraces on the top.
 
Thanks BadOleRoss. Yah the way one builds a house wall is what I was thinking of doing, Ill definately beath it up then, and the top bracing.

Another question, How do I secure the pond liner to the top frame without putting holes in it or tearing it?

I figure the total cost would be $600+ tax if I get everything locally.
 
As far as the liner, I would place the liner in the tank carefully and fold the corners so it looks as good as it possibly can inside the tank. You dont want it to look like you just threw it in there. After you get the liner in place, I would leave the extra part of the liner hanging over the top edges of the tank. I'd fill the tank allowing the liner to work its way into place. Once that was done, I would fold the liner over the top place and tack it in place with roofing nails or something similar. Once tacked, I would trim off the excess along the outside edge of the top plate and then cover that top plate with a finish board.

was with you until roofing nails, plasticaps are about the shortest roofing nail there is and even they are 1", the plywood will be 3/4" max... NO ROOFING NAILS. lol


use 3/8" staples to tack it or use liquid nails or another sealant to glue it down.

are you adding a window or will this be a pond?

Yes, the plywood will be 3/4 max but the top plate that he will be nailing into will be a 2x8. He already said no window. You need to keep up with the conversation. LOL
