ha ha, I think it's great, I could see what you were doing right off the bat, 3/4 plywood box, 1x4 bulk heads, plus a 1/2 in outer skin over the bulkheads. People that's going to give him a 2" thick layered wall. It'll be strong enough. Give us some more pics Andrew. I like your originality. I think everyone was getting confused by the order your building it. If you had of started with a 3/4" plywood box there'd have been oohs and ahs.
