Nice stand. I'll be working on a very similar one soon for an 8 footer we picked up. Nails and joints don't play much of a part in my design because its a stacked arrangment with 8 4x4 main supports. 3/4" 13 ply voidless birch with a 2x4 frame will constitute the tank support and this will sit directly on the 4x4 main supports. I'm still trying to decide how I want the exterior.
