We pried up the warped plywood, and found rust. Nothing unexpected, and we swept and cleaned up the exposed metal. It was pretty gross under there....were we ok with that being under our floor and under our housebus, walking on it all the time and knowing it was there? Hmm....maybe not. Well, looks like we're pulling out all the plywood so we can clean the metal! Plus, we'd save almost an inch of headroom!

|Rusty floor. Ick. We don't want that under our nice housebus interior|
Two hammers and some extra 1x1s will go far in a quest to pry up 26 year old plywood that is copiously screwed and nailed down and all that hardware is rusted to the floor. This day made me very sore afterwards!

Framing the floor! We are using a combination of "furring strips" (what kind of name is that??) that are 0.75x1.5" and ones that are 0.75x2.5". We put the skinny ones all along the perimeter, around the wheel wells, and around the built-ins. The fatter ones are placed across the width of the bus where our subfloor panels will meet, so we have enough space to screw everything down. Then the skinny ones will go in between the fat ones, to make each widthwise board 24" apart. I sure hope that makes sense to someone besides me! Maybe I will draw a diagram for the next post. We use Teks self-tapping screws for attaching the lumber to the metal, and those things are awesome! Also, we only had to unscrew and reposition two boards for the whole floor, and I thought that was pretty great.
