Making Cube out of 2 x 33G?

[Der_Iron_Chef]

Update: I've inquired at several glass places, and for a 3' x 3' piece of 1/2" glass (for the bottom), it will cost about $250! Not really in my ballpark right now. On to some possible solutions.

What about using 3/4" plywood for the bottom of the tank? I've read many articles/threads regarding DIY plywood tanks, but I've never seen anyone just use plywood for the bottom piece. As I understand it, silicone will bond glass to enamel, but not bare wood. Obviously, it would never be just raw wood. But if I were to prepare the piece with the appropriate 2-part epoxy, etc., would anyone see any problems with doing this? Why or why not?

actually, no, i do not see a problem with this. GL with your idea, just be careful with some epoxies, as they may degrade easily when you have aquarium life sitting on top of them, and mix into the water.

Fibre glass may be an option as you can get an incredibly strong peice of wood with a good coating. *experience*

Why not do a wood/glass combination. See if you can buy just the glass for a 33 here http://go.to/interamerican and use 3/4" wood and the 2 side pieces glued to the wood 18" + 18" = your 36" hence a bottom for your sides. Now your using strictly silicone for adherence. Not sure if it would work but now your looking at around 50$.
