Buffer Mandrel Blueprint - 1" x 3" Shaft with 5/8"-11 UNC Threaded End

This document is a simple dimensioned drawing (blueprint-style sketch) of a buffer mandrel — a shaft used to mount a buffing wheel to a motor or drill. The drawing shows a cylindrical body in side profile with a smaller-diameter threaded stub extending from one end. Four dimensions/specifications are labeled: the main body is 1 inch in diameter and 3 inches long, and the smaller threaded extension is 3/4 inch long with a 5/8"-11 UNC (Unified National Coarse) thread specification. No material, tolerances, part numbers, title block, date, or vehicle applicability information is shown. The drawing contains no year, make, or model references; it is a generic shop-tool fabrication sketch rather than a vehicle-specific service document. A reader could use this drawing to machine or order a buffer mandrel with these dimensions: turn a 1" diameter bar to a 3" length and cut a 3/4" long 5/8"-11 UNC threaded section on one end to accept a standard buffing wheel adapter or nut. The document was uploaded to a 1998 Lincoln Mark VIII gallery, presumably as a tool used for paint/body buffing work, but nothing in the drawing itself ties it to any vehicle.
