Here are the photos of the naked frame.
I think, overall, it's not too flimsy, considering once the hull plates are installed.
With the exception I mentioned about the right mandible, it's pretty rigid.
Once the plating it layered on, considering the plates join it different angles than the frame, it should stiffen up even more.
I had assembled the frame to assess if I wanted to use the photoetch gunner stations.
I am of the feeling that the gunner stations and their connecting tube act as the main support for the center of the model. I fear the photoetch would not provide the same support. I would have liked a PE set that would have acted as veneers on the existing plastic. I know the shape of the PE stations are more accurate, but I have concerns about support.
One photo shows the support beams at the rear. I would have liked to have see a few more of these arround the model. I know there are two more, but they bridge between hull plates, not the frame.
I would definitly only handle the model from the sides.
I would also think that even if you don't plan to use the hold, I would still install the walls for more support of the top.
I saw that on one of Ian Lawrence's builds, he laminted the inside with fiberglass.
I've considered, once the hull halves are built, running plastic welder along the inside plate seams.
I, too, have wanted an interior bracket to make a central mount, but I would want to be able to use the hold.
