Buy two nail punches then will fit in the holes of the disk. Then grind them down about a 1/8 of a inch so they will still fit firmly the holes. Grasp the two punches with your parallel pliers, #235 in your Schaff Catalog. Then have your partner hold down the punches with the palm of his hand. Turn the disk counter clock wise and they should come right out. Richard Bittner RPT See you in Dearborn 1996
