Adriatic posted:PAUL ROMANO posted:Dave- 072 curves and swivel details. Hope this answers your questions.I can't say for sure for Dave; but no, it was great to see but missed one part .
Does sliding of the pipe occur? ( Why? To compensate for the changed distance of pivot points fom "a"to"b" once the cars are in a curve vs straight).
If not, does the pipe flex some? (Dave asks)
Or does cribbing slide and pivot? (seems to only pivot)
No compensation for it needed at 0-72?
The whole point (reason😊) being at some max angle between cars in curves there is bind with stationary pivot alone.
Would it run on say 64" or 58" ? (ugly overhang, etc. aside ) If the pipe slides it "could/might/"almost but trucks hit"/etc.)
In real life the pipe is either cupped loosely or is making up part of the rolling structure. So does the pipe slide loose, or does the cribbing below allow fore and aft shifts to allow for slack travel between cars well as the angle shifts without putting pulling stresses on the pipe?
No, the pipe does not slide or flex, nor does the cribbing slide or pivot. No compensation needed for it on 072 curves. I ran this car at my club, NJ Hirailers, through reverse curves of 072 and greater with no problem and no binding at the pivot points simply because the pipe just swivels on curves.
