Roger on the dome, thanks for setting me straight. I'd be very interested in purchasing the new dome from you, when it's ready. I won't glue mine on so I can change anytime.
Another mistake the kit made is that the saucer, when viewed edge on, should not have a symetrical shape regarding the top and bottom discs. The top disc should be quite a bit taller than the bottom disc. I found a great set of reference drawings for the ship, inside and out, (and plenty of behind the scenes info about the movie) in a new book, "The Saucer Fleet" by Jack Hagerty and Jon Rogers, published by Apogee books. You can purchase a copy from Jon Rogers here:

It's a work of art, and the chapter on "Forbidden Planet" alone is worth the price.
Thanks for the compliment- the seams are not perfect, but if you dim the lights and stand back far enough, it looks good! I gave it a coat of Pledge/Future floor polish which gave it a nice shine.
Have you built one of these models? If so, how about showing us a photo?
