Hints of hope
I made a new loop for the centrifugal apparatus (see previous posts tagged: string) made from outdoor extension cord. Nice round cross-section, high density, not too stiff. It worked much better. With the greater weight, the loop was more stable, and didn't require a backing pinch roller or the teflon side guards. I got a distinct difference from an elongated oval at rest (aspect ratio ~4:1) to an egg shape with an aspect ratio of ~2:1 at a speed of ~8m/s.
The increased stability is very welcome. Theoretically, as the speed increases, the tensile loop should become more rigid, more like a solid hoop. Less likely to fall off the roller. Signs seem encouraging.
I need more speed. Tomorrow I'll carve an even larger pulley on the lathe and swap it in.
