John, for the horizontal bar guards on the end platforms, that bolt to the collision posts, is that solid rod or hollow tube?
During my N5e bash, I modeled those bars with rod and flattened the ends with a very fine finish nail set that had a dome-shaped inset head. I used brass rod and the nail set rendered a very nice example of a flattened end with bolt head. Now I'm thinking hollow tube of the same diameter may work better.
and oh yes, powerful optics are definitely necessary!
