ABSTRACT:
The invention discloses a method of drag finishing a housing for use in conjunction with a drag finishing machine having a center spindle adapted to revolve around the vertical axis, a tub containing drag finishing media with the outer extent of the tub positioned radially outward of and below the spindle, a work station depending from the spindle with the work station being movable between a raised load position and a lowered dragging position and adapted to releasably receive a housing to be drag finished, the housing having a longitudinal center plane. The method discloses the steps of attaching the housing to the work station while the work station is in the load position such that the center line of the housing extends radially from the work station, canting the center plane of the housing at a first angle with respect to the horizontal, lowering the work station to the lowered dragging position and thereby lowering the housing into the media, revolving the housing in a first direction about the vertical axis of the spindle whereby the housing is dragged through the media in a first direction, and reversing the direction of revolution of the housing about the vertical axis of the spindle whereby the housing is dragged through the media in a second direction.
