Wing walk ply question.

Dunno, that's what I was asking. I've laminated two pieces of ply
together before, just was wondering if it was practical or advisable to
do it curved.

I would be very surprised if your one ply of 1/4" ply would not conform to
the curve you need. Astonished, even! g

Don't forget that the curve is part of what gives that thin of a piece of
plywood the ability to carry your weight.

Is there any other structure to help out? Extra stringers, or anything?

I would think there should be no more than 6" to a stronger structure as you
measure parallel to the grain of the ply face, and perhaps 9 or 10 inches
between supports as measured across the grain.

Are those types of numbers close to what all of you other wooden
homebuilders have found in your plans?

I am going with these types of numbers based upon my knowledge of being a
woodworker. I am curious if that is what others have found.

Well, the ribs are truss type., the two that will support the walk I've
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'm 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.
