Abstract : A U-shaped bracket has bearings holding a rotatable shaft. The shaft supports a pair of conical disks with their apexes facing each other along the shaft. Nuts are positioned along the shaft outside of the cones to position the cones. A cylindrical strength piece and a cylindrical test piece are inserted over the shaft with the test piece being outermost. The nuts tighten the disks against the test piece with the strength piece being of such a size to inhibit the disks from damaging the test piece. The bracket has an extension affixed to it that is attached to a testing machine. The cylindrical test piece is suitable for rotation and has a coating bonded to it. The testing machine peels the coating at a constant 90 deg angle from the test piece and measures the peel strength upon the test piece being rotated.
