This is Delta item no. 905-03-013-1493. Delta does not make these anymore !  This is a tapered starting pin for Delta's Heavy duty and the light duty shapers, along with all the old Homecraft shapers.  These are useful when you are starting your stock on curved surfaces.  You brace your wood into the pin to ease it into the cut. Some use two pins one to start the work and a second when you are tailing off your stock at the end , so again you brace your wood on the second pin when finishing the shaping procedure.  They would probably fit other shapers also. If you bid on the item and win you agree to pay for the item, within four days.
