ISOLATORS compress and shear in reaction to these forces, so it is normal that a press will rock to some degree. The softer the isolator is, the more the press will rock. DEPENDING on the press and isolators, one-quarter INCH at the crown is not unusual. The human eye tends to magnify motion, so what looks like EXCESSIVE motion may not be. Yes, to an extent.
