Panfar, first of all....Im jealous you live in Ormond Beach. Secondly, let me make an observation and you might be able to clear it up. Regarding the plastic model, dish height looks thinner than your project. Your reference pics might show a thicker sidewall than the model, but by comparing the model to your project, the sidewall on the saucer looks high. This might be because of the choice of materials (plywood VS thin Styrene for the skin).
If you are happy, Im happy. Just wanted to give you a fresh set of eyes. Thanks for the observation you have a good eye. I will be sanding the side to an angle to match the upper skin so I should lose almost a 1/4 inch from the perceived height. Please continue to keep me on track.
BTW....looks like you are making MAD progress.
PS. Its kinda cool how certain ships 'call out to you'. I might not care for a 20,000 Leagues under the Sea sub, but there are plenty of people who it does. Voyager was a great bird and series.
