the skin is added

I lay the bottom of the board first. I figured this would give it some strength. But after it was glued it still felt a little to flexible so I decided to use some expanding foam to give it more strength and float.

When this dried I sanded it back to the wooden ribs. It feels a lot more stable now. And now its time for the top covering of cardboard.

Maybe I should ask Apple for sponsorship. The board is starting to feel more rigid, to the point that I wish I didn't use the foam. At least using the foam will give some float if the board turns to mush.
