I just stumbled onto this wonderful Japanese Website where the author dorakudo(?) recreated the Yamato 2199’s Wave Engine in 1/100 scale. Initially, it was 1/144 but when he saw the Gundam 1/100 figures, the scale became 1/100.
There are five pages of WIP which shows his tremendous skills and attention to detail. Here is the main page of the author and you might need Google Translate:

This is the link to the actual WIP page of the Wave Engine:
