My plans don't give a lot of detail about my wing walk but it's for a
truss
rib mostly wood wing. The walk is supposed to go from the front spar
to the
trailing edge and should be 1/4 ply. my question is will a piece of
1/4 ply
bend around the curvature of the wing (Clark Y) or should I laminate,
say, two pieces of 1/8 ply? If I were to laminate, what would the
best way of ensuring i got decent contact between the top and bottom
surfaces?

The designer should know, if it has been built before. I would think
that you would trust him, if you are trusting him for your life on the
rest of the design.


I do trust him, but I didn't get to ask him before he died! It's one of
the details he kind of left yto your imagination...

That small bend should not be a problem. If you do laminate, use a
1/8th inch notched trowel to spread adhesive, place the two together
firmly on a flat surface using another thicker flat surface on top to
apply some pressure, then wiggle the two pieces back and forth a
little. Apply the two pieces at one time without taking apart again.


Well, what I was actually asking is if I could laminate the two pieces
to take the curve in the wing. I realise this is basic stuff for a lot
of you guyus, but I've never bent realatively thick ply before and I
don't want to make a mess out of the rest of the wing trying..
