Acrylic Plastic Piston

First attempt at doing some close-up with my Tamron 70-300mm Lens with Macro. Part was machined out-of-tolerance by .005

Now you've got me interested!
I assume that you mean 0.005 inches not 0.005 mm! Either way I can't see from here where it is out of tolerance. Which feature is not within tolerance and what was the tolerance? Is that chatter marks, on the outer cylindrical surfaces, from turning, or is it from a previous casting or drawing process?
Some suggestions: I would have been tempted to photograph it with the longitudinal axis tilted to the lens axis to show more surfaces and to give it an isometric appearance, or viewpoint. In addition I suggest laying your micrometer or vernier calliper alongside, across or inside one of the diameters or length; to indicate work going on. Throw in some perspex swarf for added effect.
I assume this is demonstration/ display piece in-which case, it must be oversize, otherwise it could still 'fit'.
Regards

It's a really interesting macro shot. The lights and the colours are nice.

You are correct about the .005 out of tolerance. .005 inches. You gave me an idea for another shot. This time I'll try and shoot an image of the same thing, but with a precision tool that I still have left over from my Trade. Now you've got me interested!
