The scaif consists of a hard disk, parallel to the floor. The disk looks like and is rotated in the same way as a potter's wheel. On the top surface a film of olive oil and diamond dust is placed. Surrounding the disk is a circular frame to catch the oil that is spun off as the disk is rotated. An older model of the arm piece for the stone.
Lodewyk van Bercken was a Flemish diamond polisher who invented the scaif. This ingenious polishing wheel enabled him to quickly cut facets into diamonds with precision. The scaif transformed the diamond trade. It opened the doors to the creation of complex diamond cuts which otherwise would have never been possible. The scaif is still used ...

Early radial flapwheel, for use with an electric drill. A flapwheel and the related flap disk is an abrasive disk, used for metal finishing. Unlike the simpler flat disks, made from a circular flat sheet of a coated abrasive, a flapwheel is made of multiple overlapping small pieces or 'flaps', bonded to a central hub.
A gemcutter then selects the shaping wheel and applies abrasive compound. They hold a lapidary stick against the revolving shaping wheel and lapidary disk to further shape stone and grind facets. Depositing stone within a barrel with both water and a grinding/polishing medium and either vibrating or rotating said barrel using friction to grind ...
The wheel type (e.g. cup or plain wheel below) fit freely on their supporting arbors, the necessary clamping force to transfer the rotary motion being applied to the wheels side by identically sized flanges (metal discs). The paper blotter shown in the images is intended to distribute this clamping force evenly across the wheels surface.
