[ODE] Joint Question

I'm trying to simulate a "pin joint". In this scenario, one body has
a hole through which another body spins: this is shown below in an
exquisite ASCII figure.

The line of stars should rotate around the central axis running
through its length. The rectangular torus should not be transformed
by this rotation.
I tried implementing this with a hinge joint, but there is no anchor
point between the bodies. The only joint type that does not require
an anchor point is the slider joint, which allows a degree of
translational freedom instead of rotational freedom.
I'm worried that simply letting the line of stars spin in the torus
without a joint, i.e. keeping it in place with only contacts, will be
very computationally expensive and less physically accurate.
Does anyone have any suggestions for simulating this kind of scenario?
