There are NO SHAVINGS inside of the lenses! Man, this has been yet another case of newbies making a huge deal out of something they do not understand. Nikon has published an official response:
“The 70-200mm f/2.8G ED AF-S VRII lens features a component in the lens design which may appear to have surface pits or a rough texture when viewed through the front lens element. This rough surface appears in a very small confined area within the lens barrel and is caused by air holes remaining in the metal portion of the lens during component construction. Due to the magnifying effect of the front element this rough surface will appear greatly enlarged when viewed through the front of the lens."
"This components function is to reduce and remove internal reflections from the lens and due to this the texture of the surface will have no effect on the lenses performance or operation. Nikon would like to assure customers that the lenses optical performance remains unchanged and that this component will not release any dust or particles into the lens itself.”
Some photos are available on the the Flickr user's group on the subject!

One of the better photos is this one

which shows the edge of a lens element. What is good about this photo is that it allows people to see what the edge of a lens element looks like where it joins the edge of an inner spacer or lens barrel assembly and a strong light is shine through the lens:

That is a Nikkor 24-85mm f/2.8~4 zoom lens
Here is a shot of the "threads" in a new 70-200, which are magnified by the front element of the new 70-200 VR-II lens. Only, these are not "threads", these are anti-reflection baffles, designed to stop light reflection. Most better lenses use either flocking or physical baffling (ridges) to stop light from bouncing round

As for the threads people are alleging are 'missing' or 'damaged':the plastic baffling is made by a moulding process, and the "missing parts" (lol) are caused by air bubbles in the manufacturing process. In a non-moving part that does nothing except stops stray light.
What's funniest about this ENTIRE thing is that the lens design has excellent resolution, contrast, flatness of field, low vignetting, and superior optical performance, but newbies are looking into the lens and getting worried. Why is this scenario so amusing,and yet so annoying, and so Internet-Retarded??
Well, pick out **your** very-best performing lens, and then take it in hand and shine a strong flashlight into it from the lens mount side forward and take a look inside. If the lens is a year or two or three years old, you will probably be literally aghast at how much crap is inside the lens. Your lens. Your "best" lens.
