Abstract
One embodiment of a device for positioning an object to be ground independent of the grinding tool having an armature shaft for holding an object, mounted by means of an armature and armature collar and attached to a mast, which is attached to a base. The armature shaft is used to position the object to be ground at a face angle determined by the combination of the vertical positioner length of the armature relative to the surface of the independent grinding tool. The rotational angle of the object to the grinding tool is set and can be repeated as needed by the indexed angle selector and the keyed receiver.

A faceting jig operable to set a face angle for grinding a facet upon an object mounted to the faceting jig, comprising:
- a base;
- a mast mounted to the base and projecting vertically upward from the base;
- an armature containment cylinder;
- a collar connecting the armature containment cylinder to the mast, the collar being operable to permit the armature containment cylinder to rotate to a selected angle between a vertical orientation and a horizontal orientation and being operable to move vertically between a plurality of locations upon the mast;
- a vertical height lock operable to suspend the collar at one of the plurality of locations upon the mast;
- an armature shaft disposed within the armature containment cylinder, wherein a longitudinal axis of the armature shaft is aligned with a longitudinal axis of the armature containment cylinder and wherein the armature shaft is operable to rotate about the longitudinal axis of the armature shaft;
- a facet angle selector affixed to an end of the armature shaft, wherein the facet angle selector is annotated with facet angle indicators ranging from zero degrees through three hundred and sixty degrees and is useful to select the facet angle of the object;
- and
- a facet angle selector lock affixed to the end of the armature shaft operable to lock a rotation of the armature shaft and selectably fix a facet angle of the object;

- and
- a facet angle selector lock affixed to the end of the armature shaft operable to lock a rotation of the armature shaft and selectably fix a facet angle of the object;
- selecting a facet angle of the object by rotating the facet angle selector relative to the armature containment cylinder;
- locking the facet angle of the object by utilizing the facet angle selector lock;
- moving the collar to one of the plurality of locations upon the mast;
- and
- rotating the armature containment cylinder to the selected angle;
- wherein the collar includes:
- a vertical collar portion attached to the mast and being operable to move vertically between the plurality of locations upon the mast;
- and
- an armature collar portion attached to the vertical collar portion, attached to the armature containment cylinder, and being operable to rotate to the selected angle;
- wherein the armature collar portion and the armature containment cylinder include mating key features operable to prevent the armature containment cylinder from rotating relative to the armature collar portion;
- wherein the armature collar portion includes an armature collar tensioner providing for selective movement of the armature containment cylinder forward and back within the armature collar portion;
- and
- further comprising utilizing the armature collar tensioner to move the armature containment cylinder within the armature collar portion.
