RE: Shear web question
I wasn't aware it had ever been any different. If your shear webs are glued to the top and bottom spars, and to the ribs to the left and right of the shear web, you have secured a "box" of attachments so that will be the strongest arrangement.
By the way, the grain of the shear webs should run vertically for the greatest amount of stiffness. That is because the shear webs will be rectangular in shape, and you want the wood fibers to be cut in the short direction.
