Claim 18:
19. A method of manufacturing a setting tool for use downhole, the method comprising:
forming a mandrel having an upper portion and lower portion, wherein the mandrel has a first end and a second end;
forming a barrel piston sized and configured to extend over an exterior of the mandrel;
forming a lead portion on the upper portion of the mandrel proximate to the first end, wherein the leading portion comprises seal grooves for receiving O-rings;
forming an engagement portion on the upper portion of the mandrel adjacent to the lead portion and closer to the second end of the mandrel than the lead portion;
forming a wrench-application portion on the upper portion of the mandrel adjacent to the engagement portion and closer to the second end of the mandrel than the engagement portion, wherein a shoulder is formed on the mandrel between the engagement portion and the wrench-application portion and the diameter of the wrench application portion is larger than the diameter of the engagement portion;
forming a retaining cap sized and configured to extend over a portion of the exterior of the mandrel;
coupling the retaining cap to a first end of the barrel piston;
disposing the retaining cap and barrel piston over a portion of the exterior of the mandrel;
forming a first shear-device hole in a portion of the upper mandrel for receiving a shear device;
forming a second shear-device hole through the barrel piston and in alignment with the first shear device hole when the setting tool is in an in-line configuration; and
disposing a shear device in the first shear-device hole and second shear-device hole.
