Hi Phil
I'm also relatively new to Vader Props.
As I understand, this has a lot to do to get to the bottom of the secret things (known as the path to the dark side...
).
I mean it's not exciting to get one ready-made plan.
For the design and construction of my ESB Chestbox I knew only one measure that has been mentioned several times in various forums.
From this and from my Fenixprops Rods I derived all other dimensions.
I was already surprised to see the measurements of the rocker switches on NHM's posted image. They correspond to +/- 1mm my derived dimensions.
Of course it was much (research) work. But the satisfaction is ultimately greater if you develop this from the scratch and then see after, you're close to the real thing.
I post here even though my basic plan of my ESB chest box.
http://www.darth-vader.ch/props/chestbox_h-2.pdfIt's certainly not 100% accurate, which can ensure no one or very few people who were close to the originals (there were also different screen used versions ...) or still are.
A few details are mentioned in German, but these are not so important.
Based on this plan, I built my 3D CGI version:
and my real chest box:
Sure it's not the 100% accurate thing, but one can always do things better. It is only my first modest attempt.
Hope this helps and motivates you to go deeper into the research process, which is really exiting to do.
