OK, so I watched the following video… I think it is worth sharing.
First of all, I applaud the maker of this model for buying some plastic aftermarket for his metal ship.
I always found it incredible people can and do work with such a great precision in such a small scale. Well, there is part of the explanation in the video: specialized tools to help you. (Not really a surprise but it is nice to actually see it in action.) Regardless I doubt my results were like this if I got all this equipment to work with. Simply astonishing.
