Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. 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. 2. The method of claim 1 , further comprising machining a slot on the first portion of the spindle. 3. The method of claim 2 , wherein the slot is positioned on a side of the first portion opposite the collar. 4. The method of claim 2 , wherein the slot is configured to receive a portion of a wobble plate shaft of the reciprocating saw. 5. The method of claim 1 , wherein the collar is configured to receive a portion of a wobble plate shaft of the reciprocating saw. 6. The method of claim 1 , wherein the first portion of the spindle is integrally formed with a remainder of the spindle. 7. The method of claim 1 , wherein the collar extends above an outer surface of the spindle. 8. The method of claim 1 , wherein the collar surrounds the throughbore. 9. 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. 10. The method of claim 9 , wherein the slot is positioned on a side of the first portion opposite the collar. 11. The method of claim 9 , wherein the slot is configured to receive a portion of a wobble plate shaft of the reciprocating saw. 12. The method of claim 9 , wherein the collar is configured to receive a portion of a wobble plate shaft of the reciprocating saw. 13. The method of claim 9 , wherein the collar extends above an outer surface of the spindle. 14. The method of claim 9 , wherein the collar surrounds the throughbore. 15. The method of claim 9 , wherein the collar is positioned adjacent the throughbore. 16. 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 adjacent the throughbore, wherein the collar extends from an outer surface of the spindle and surrounds the throughbore. 17. The method of claim 16 , wherein the slot is positioned on a side of the first portion opposite the collar. 18. The method of claim 16 , wherein the slot is configured to receive a portion of a wobble plate shaft of the reciprocating saw. 19. The method of claim 16 , wherein the collar is configured to receive a portion of a wobble plate shaft of the reciprocating saw. 20. The method of claim 16 , wherein the first portion of the spindle is integrally formed with the remainder of the spindle.
