<p>A fixture for facilitating sandblasting of a generally cylindrical object includes a frame, a rotary table mounted on the frame, and a moveable blast head which can direct a flow of grit onto a cylindrical object mounted on the rotary table. The blast head may be movable vertically so that it can be extended down into the interior of a cylindrical object. The blast head may also be movable in a rotational fashion. Further the blast head may be movable in horizontal directions so that the blast head can be moved relative to a vertically extending cylindrical surface of a cylindrical object mounted on the rotary table. Controlled movements of the rotary table and the blast head allow uniform sandblasting of the cylindrical object.</p> |
