Abstract

One embodiment of a device for positioning an object to be ground independent of the grinding tool having an armature shaft (102) for holding an object, mounted by means of an armature (114) and armature collar (124) and attached to a mast (110), which is attached to a base (138). The armature shaft (102) is used to position the object to be ground at a face angle determined by the combination of the vertical positioner (126) length of the armature (114) 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 (118) and the keyed receiver (116).

Claims2

Dependent claims

A method for holding an object to be ground independently of the grinding tool, comprising:

a) a base that permits stably mounting to a surface,
b) a mast mounted to said base,
c) a vertical collar mounted to said mast and capable of:
a) moving vertically along said mast,
b) being secured in place on said mast,
c) rotating freely about the mast
d) an armature collar secured to said mast by said vertical collar allowing rotation parallel to said mast,
e) an armature held by said armature collar and capable of:
a) sliding through said armature collar to a to allow selection of armature length,
b) being secured in place by the said armature collar when said length is reached,
f) an armature shaft for attaching an object to be ground contained within said armature,
g) an angle selector mounted to said armature that allows preset angles to be set and repeated.
