An apparatus and method for making possible an infinite variation in the adjustment angle of a spindle assembly makes possible a rapid changeover for testing the dynamic properties of elastomeric objects. In spindle assembly (10), wedge rings (18, 20) having wider portions (22, 22a) and narrower portions (24, 24a) interposed between a spindle (12) and an axle assembly (17), whereby the relative placement of the wider portions (22, 22a) and the narrower portions (24, 24a) determine the angle of the spindle (12) relative to axle assembly (17). Indicia (48, 48a) on the wedge rings (18, 20) make possible quick determination of the exact angle. Means (50, 50a, 67) may be provided to make easier rotation of the wedge rings (18, 20). |
