Thanks Wobble, will try & post more close ups soon.
Now that I know the amount of space I need to fill (32" x 9"), I'm starting on scratch building 2 sets of grandstands. I started by cutting risers out of .060 Evergreen Styrene. I buy it in 12" x 24" sheets. The great thing about styrene is that you do not have to cut all the way through, simply score it with a utility knife & it snaps clean.
