This would be adapting the ring to fit a piston-valved instrument.

Looking at the thing, I suspect that picking the horn up by the ring wouldn't be a problem if the force vector were axial to the threaded stud, as that bit of steel probably has more than enough tensile strength to support the largest tuba in current production.

What would get you into trouble is applying an off-axis force to it--I suspect that there's very little shear strength to that miniscule stud.

I'm sticking with a generously-sized fixed ring on this one.
