There you go with all those pretty little objects I was talking about.  You must have two machines or a time warp device seeing how fast you render and reply.  I have some of those brushed metal mats.

I can't see any reason to pursue the machine mark surface if you, the wizard, have failed the attempt in the past.

Imagine a cast iron automotive cylinder head that has the flat surface milled where it meets the engine block and the machined out combustion chambers and shiney surfaces where the valves seat.  (I worked in an automotive shop one summer in high school)

Well I off to sunrise service at church.
