Clapper for my Whitcomb Blaisdell planer. Taper pin was worn and bore was wallered out in the clapper. Clapper to box was "not too bad" but I wanted everything tight. Rescraped box and clapper where necessary, and made wedge gib to take up lost space. Wedge gib is hardened O-1. New taper pin is hardened S7. 1/4" per ft taper pin reamer was re-sized out of a junk brige reamer.
