I think your suggestions are good ones; I'll make sure to incorporate them into our procedure. I decided a while back (and this is, perhaps a result of having done reverse...

Berkshire,
To a degree, it helps. Our plotter will accept up to .010" thickness, although I was thinking that the mylars for longerons were thinner (I worked in buildings 1, 2 & 3 (if I have the numbers right). I worked as class 4 inspector on MD-11, Tomahawks, Cruise Missiles and ACM's, then...
