Gents:
The basic concept of what's being done here eludes me, as the old gray matter just won't allow an image match with the words so graciously shared. I hesitate to drill down on this any more, but am afraid I might be missing a good wingtip technique (I've grown to dread 'em).
I understand the laminating. Perimeter I kind of get in this context (or maybe not). Sorry Brett, but your word "bow" has three definitions in my noggin.
Again, much obliged.
Moe...
