nobody is still having a problem:
Hi Jan,

as you mentioned, I just change the elif to else:

###########
def ossillation_rotation():
	for b in O.bodies:
		if isinstance(b.shape,Facet):
			rotationAngle = b.state.rot().norm()
			if rotationAngle > 0  and rotationAngle <= math.pi:
				cylinderRot.angularVelocity=rate
				coneRot.angularVelocity=rate
			else:
				cylinderRot.angularVelocity=-1*rate
				coneRot.angularVelocity=-1*rate

############
even if I use this, the shaft still rotates in one direction.

best,
Yong
