Another way to bend propellers is to clamp the center of the blank in a vertical position, and with two clamps made by sawing into the ends of two pieces of wood, [Fig. 258], a cut wide enough to take the thickness of the blank, and deep enough for the width, bend one blade forward and the other back, [Fig. 259]. The small clamps on the propeller blades should be placed at equal distances from the center, and should be given an equal amount of twist. The small clamps on the blades will not be forced over until they touch the base, so blocks of equal size should be used as stops in the operation of twisting. The clamps should be secured in the last position by means of cord to the base until the propeller is dry.
