The back side of the current deck has the girders represented in a sub-scale manner... just enough to give the suggestion of girders and about the same depth as the kit parts.

As I said, I am awaiting a kit so I can get started. *IF* the girders are indeed separate parts, the etching will be very light and may just be done as lightly done lines for them to slip into instead of the raised effect on the current 1/450 deck. I do hope the girders will allow me to do it with placement lines instead of raised details... it takes less time and time is money when the laser cutter is involved.

less time = lower price.

Thanks again for the response. I think it's great that you're basing your product off of the actual kit for maximum fit effectiveness. I know that I'm not alone in looking forward to seeing what you come up with.
