Turntables

I'm cutting down some ME 150' plate girders for my Marshall Pass turntable. It's rather slow going to replace the rivetted sections at the "new" bottom, which got me to wondering if I should be doing some for Sargent at the same time.

I know the Marshall Pass turntable was 67' and the Sargent table only 62', but the way the ME plate girders work out I've got a choice between 58', 65', and 72'. Which means they'll both be 65' anyway.

I've only found 2 pictures of each turntable, but from those the bridge girders look identical (with slightly heavier wooden railings at Sargent).

Does that sound right?

Thanks,
Jeff.
