ABSTRACT An adjustable bolster block to be disposed between the ram or bed of a brake press and a die is disclosed which permits crowning to compensate for deflection of the brake press under loading. The bolster block includes a double wedge support coupled to the ram or bed and a die holder to hold the die, Two wedges are sandwiched intermediate the wedge support and die holder, one on each side of a central plane passing longitudinally through the bolster block. The wedges have cam surfaces which engage complementary cam surfaces on each of the wedge support and die holder. Movement of the wedges toward or away from each other varies the spacing between the wedge support and die holder. The wedges can be bent in directions towards and away from each other symmetrically about a central plane to vary their separation along their length and to thereby vary the spacing of the die holder from the wedge support along their lengths so as to crown the die holder, The symmetric configuration minimizes net bending moments acting on the die holder tending to bend or twist the die holder in directions normal to the central plane.
