@dave I'll post the wires in as soon as I get through my morning mail. I cheated a little on the heat sync and the part with the holes is currently trimmed nurbs with poly parts one each end. I'll split it apart so you can see. It was easiest to put perfect holes with nice rounds by projecting a circle from the top and sides. I do intend to redo it in polygons and I can use the nurbs model as a guide.

@dj It's pretty basic settings, I go for production or production fine trace, final gather, no lights, med light grey env background color, MR amb occ node piped to a surface shader, 128 samples, and I measure the max distance or just guestimate it that light rays would have to travel (in this case the max width of the heat sync thingy) and double it for distance, and then play with the spread from .8 to 1.6 until I get an acceptable look and 85mm portraiture lens.
