Yeah, that's 5/4.   I have nightmares about the cost of it.

I think 5 feet is the longest that could be required.    The nine-inch 
dimension is based on the apparent number of boards and the 
probable total height of the box hull.

No, but I don't have room for it if I'd thought of it.

I suppose it needs to be smooth enough to avoid any big
splinters.   Someone would make a fortune off sandpaper
for the project.

Well, yeah ....   Plywood will bend a bit better than a one-inch chunk of
pine.

I don't know what Lake did.  I assume he thought of that, but he
might have had them overlapping and braced internally.   No one
seems to know anything at all about the interior of Junior.

Not of my idea, but photos are at Jeff Lake's  website:
