Abstract

A method of fabricating very small diameter deep passages is provided. The method of fabricating very small diameter deep passages may include fabricating a recess (206) in a first side (202) of an article (200). An article passage (216) may be fabricated between a second side (204) of the article (200) and the recess (206). An insert (220) may be provided sized to fit the recess (206). An insert passage (230) may be fabricated in the insert (220). The insert (220) may then be secured in the recess (206), with the insert passage (230) and the article passage (216) aligned.
