I've long had problems picturing the way that the spoke in Death Station works. Hope someone here can help me understand it (or figure out a way to explain it).
The image provided is an excerpt from my version of Death Station, but I removed lots of stuff and added the lift shaft and a crude representation of the Pinnacle.
Anyway, if we look closely to the center, I'm assuming that gravitics would keep sophonts in the spoke always pointing towards the same surface, but the ones in the Pinnacle would point to the floor of the ship.
Assuming the airlock points to the left on this image, at some point, the person inside the ship would need to rotate to adjust to the new gravity, or have a weirly shaped ladder.
Alternatively, consider the Pinnacle stationed at 90°:
Here, a stair seems less likely, but rotation still unavoidable.
Have you thought about this? How do you handle it?
This is one of the many reasons why the lab ship design makes no sense.
