Claim 7:
8. A method of manufacturing a reversible spray tip for a fluid applicator, the method comprising:
providing a cylindrical stem having a longitudinal axis, the longitudinal axis defining an axis of rotation of the stem;
machining a channel that extends through the stem in a direction transverse to the longitudinal axis of the stem;
machining a first part of the channel to widen the first part of the channel to define a first portion and to form a second portion and a third portion, the first portion comprising a second part of the channel, the second portion comprising a frustum that widens as the frustum continues in a direction moving away from the first portion, and the third portion extending from the second portion toward a first end of the stem and having a diameter greater than the diameter of the first portion;
machining a first part of the third portion to define a pre-orifice portion and to form an insert receiving portion, the pre-orifice portion comprising the first portion, the second portion, and a second part of the third portion, the insert receiving portion extending at a continuous diameter from the pre-orifice portion and defining an opening at the first end of the stem;
inserting a pre-orifice insert into the insert receiving portion through the opening defined by the insert receiving portion such that the pre-orifice insert is disposed wholly within the insert receiving portion and is configured to receive fluid from the second part of the third portion and such that the insert receiving portion extends past an end of the pre-orifice insert; and
securing the pre-orifice insert into the insert receiving portion.
