mm and an inner hole diameter of 12 mm or smaller cannot be picked up by their inner hole therefore in a third embodiment of the present invention a first assembly as in fig7 having two carriers 1 in the form of a double mandrel 23 supports the outer diameters of the disks referring also to fig8 a second assembly 24 may provide additional support for the outer diameter of a disk 9 on the first assembly 23 the spacers 21 are no longer ring shaped but are adapted to the outer contour of the supported objects 9 preferably the spacers 21 are shaped to handle several disk sizes in fig9 an embodiment of the spacer 21 of the first assembly of the third embodiment of the present invention is shown dimensions 34 a 34 and 34 b 34 indicate the vertical support for example dimension 34 a 34 indicates the vertical support points for a disk 9 having an diameter of 65 mm a groove with outer diameter of 65 mm is cut into the spacer 21 to hold 65 mm disks 9 dimension 34 a 34 should be made as large as possible to ensure accurate vertical orientation to support disks having a diameter different from dimension 34 a 34 a second groove indicated by dimension 34 b 34 is cut into the spacer.
