Keeping the stainless steel as a requirement, you might epoxy a small, high-tech ceramic magnet to the top of each SS pin.
Then, a magnet used as a probe could extract the pins, once you've lifted the sculpture enough to take off the side load on the pins.

A deep hole in the dial, shallower in the plinth. Then, stainless steel pins could be put in the deep holes, the sculpture/dial moved to the correct position, the pins should drop down into the shallow holes and hold the dial. The only way to get it off would be to turn the whole thing upside down. To drill the holes, I'd make two jigs by clamping two pieces of laminate and drilling right through them at skew angles. Has anyone tried this? Glue would be simpler but too permanent for the sculpture I have in mind. I used a similar method to hold the gnomon of the dial I showed at the BSS Exeter conference last year. Chris 51.4N, 1.3W
