Abstract
A method of manufacturing a spindle for a reciprocating saw includes machining a first portion of the spindle and forming a throughbore extending through the first portion via a flow welding process. The flow welding process includes rotating a rod relative to the spindle and inserting the rod into the first portion of the spindle, thereby displacing material from the spindle in a direction away from the rod to form the throughbore and a collar adjacent the throughbore.
