Yeah that's the pic i remembered, thanks Al. I'm sure with a little bit more thought this could easily be done and still provide adequate support.

So I was thinking a deck plate type setup with an aluminum frame that sits in the hole, floor routed slightly to sit flush and under carpet. And instead of the deck plate door, an aluminum recessed cover (carpeted) sitting flush also. Support and strength. hmmmm.

I know someone who welds and fabs, i may have to talk with him about fabbing a frame up to see.
