Claim:
1. A swivel abrader assembly, comprising: a vertically-adjustable mounting mechanism; a swivel mechanism attached to the mounting mechanism such that, responsive to first user instructions, the mounting mechanism adjusts the swivel mechanism to a predetermined swivel mechanism elevation above a preselected horizontal datum plane; an abrader assembly, the abrader assembly including an independently-rotatable abrader, the abrader assembly suspended from the swivel mechanism by a tilting mechanism, the tilting mechanism disposed to tilt about a pivot axis parallel to the datum plane; the abrader assembly, responsive to operational contact on the abrader, disposed to tilt about the pivot axis via the tilting mechanism while the abrader is rotated at a user-selectable speed; and the abrader assembly also rotatably connected to the swivel mechanism such that, responsive to second user instructions, the swivel mechanism rotates the abrader about a vertical swivel axis perpendicular to the datum plane and sets the abrader at a predetermined abrader orientation relative to a preselected datum azimuth.
