Well, the ribs are truss type., the two that will support the walk I have
covered with 1/16th birch ply. I plan to run a 1/4 inch stip alnog the
length to hold the walk surface fluch with the top of the ribs an glue
some , say 1/2 inch sq spruce betwwn the ribs every 6 " to support them
The whole thing shouldn't be too heavy, I reckon, especailly as I am only
going to install one on one side.

Yeah, the ribs are 12 " apart, so thats about right. And ther shoud be
no more than that to each cross brace as well.
