Abstract: A water ski binding having a heel piece binding with a flexible heel boot held in place with an adjustable heel member. The heel member is U-shaped and has an elongated slot in each leg. The upper part of the slot extends outward to form a shoulder and an insert having a pair of slots fills the elongated slot to permit custom fit of the heel piece.The shoulder formed in the elongated slot varies in width to form a series of recesses each of which will accept an extension of a fastener to positively lock the fastener in place when the heel binder is used as an adjustable member. A front piece binding with a flexible foot restraining boot is rigidly held in place with a shaped member. The shaped member is fastened around the periphery with a series of recessed holes shaped to accept a nut recessed below the outer surface of the rigid member.

Abstract: A pair of matched metal dies one of which moves against the other to form a mold to contain, and to apply pressure to a part and to pinch off excess material on the part. The lower die has a recess with all the sides of the recess canted outward in two steps. The upper die when inserted contacts the lower canted sides of the lower die.
