1. A method of making a fluid injector for a gas turbine engine comprising:
depositing material onto a piece of tube stock; and
machining the deposited material into a fluid injector component;
wherein the piece of tube stock is a prefilmer, wherein depositing material includes depositing material on only a portion of a circumference of an outer surface of the piece of tube stock, and wherein machining includes forming a passage through the deposited material and through the piece of tube stock to form a passage through the deposited material and into an interior of the piece of tube stock, wherein the passage comprises a joint surface; and
placing or flowing braze into a braze joint location comprising the joint surface, between the deposited material and a fluid injector feed arm and forming the braze into a braze joint in the braze joint location to join the feed arm to the prefilmer.
