Re: Forced perspective, painted backdrops and the refit Enterprise
The "real life" length of the horizontal tube can now be estimated more easily, if required - there are 10 FP segments and 3 full size segments - 13 in all, plus the conical junction to the vertical tube.
If each horizontal segment is about 4' in length then the overall length of the tube would be 52'
YMMV, of course
Great picture! But eye-balling the full size segments
and assuming Shane Johnson got the reproduction correct (he had been visiting the set) I'd get a length of almost 7' for each H-shaped segment which would put the "real life" pretended overall length of the horizontal shaft at 87' or 26.5 meters (assuming, of course, all elements are supposed to have the same length).
