ABSTRACT The invention is directed to a power driven tool for recipro- cating a cutting element such as a saw-blade or the like and in- cludes a motor housing and a drive motor mounted in the motor housing. A gear case is connected to the motor housing and the shaft arrangement is mounted in the gear case. The shaft arrange- ment includes a shaft slideably mounted in the gear case for re- ciprocating movement. The shaft is adapted to receive the cutting element thereon. A U-shaped channel yoke is mounted to the drive shaft in such a manner that the walls of the drive shaft laterally support the U-shaped channel yoke at the base of the yoke. An eccentric drive connects the U-shaped channel yoke with the drive motor for reciprocating the shaft arrangement. A method of assemblying the shaft arrangement includes the step of cutting two slots in the base of the channel yoke to define three bridges one adjacent the other bridging the gap between the leg walls of the yoke. The channel yoke is then inserted into the notch-like cut-out of the shaft so as to cause the channel yoke to engage the annular wall of the shaft in the slots at the bottom region of the cut-out. In this way, the center bridge of the channel is disposed between the inner walls of the shaft. The channel yoke is then brazed to the shaft at the interface be- tween the channel yoke and the shaft.
