So, let me make sure I'm following this... The narrow (silver looking in the photos) strips of 6oz cloth will be attached to the bottom of the wing saddle instead of using, say, 1/32" ply, for example (which is what I used). If I understand it correctly that looks like a better method since it will give you a thinner, more rigid fittet base than ply.

One of the things - among the many - that sets your work apart are these innovative techniques that you employ.
