Mike,

I build it almost a month ago, and it's been sitting in a non-climate controlled shop and so far it's rock solid. I wouldn't be afraid to put a couple wings on it for sheeting. I can tell you that when we carried it from the garage where I built it to the shop it didn't warp one bit. I'll keep you guys posted on how it holds up.

I think I started building it at around 10 in the morning and finished around 9 at night. All I can say is thank god for that new nail gun. Without it I'd still be putting nails in

I didn't think of using it for a foundation, if the whole airplane building thing doesn't work out I'll give it some thought!!

Rick
