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.

A method of manufacturing a spindle for a reciprocating saw, the method comprising:
- machining a first portion of the spindle;
- and
- forming a throughbore extending through the first portion via a flow welding process, wherein the flow welding process includes
- rotating a rod relative to the spindle;
- and
- inserting the rod into the first portion of the spindle while rotating the rod, thereby rotational friction between the rod and the first portion causes material to be displaced from the spindle in a direction away from the rod to form the throughbore and a collar adjacent the throughbore.
A method of manufacturing a spindle for a reciprocating saw, the method comprising:
- machining a first portion of the spindle;
- machining a slot on the first portion of the spindle;
- and
- forming a throughbore extending through the first portion via a flow welding process, wherein the flow welding process includes
- rotating a rod relative to the spindle;
- and
- inserting the rod into the first portion of the spindle while rotating the rod, thereby rotational friction between the rod and the first portion causes material to be displaced from the spindle in a direction away from the rod to form the throughbore and a collar.
