1. The method of making heat transfer element, comprising a. forming an elongated tubular member having a wall portion with spaced elongated external ribs extending longitudinally of said tubular member, and b. successively, from one end portion of said tubular member toward the other end portion thereof, 1. cutting fins from a plurality of said ribs simultaneously, and by means of a cutting tool having cutting surfaces aligned with respective ones of said ribs and having alternate ones of said cutting surfaces being offset longitudinally of said ribs from the immediately tRansversely adjacent cutting surfaces, and c. to thereby 1. afford a''. elongated base portions 1''. extending across said ribs transversely to the length thereof and 2''. directly attached to said ribs, and b''. free end portions projecting outwardly therefrom, and 2. dispose said free end portions of said fins in position wherein said free end portions of said fins on alternate ones of said rows are disposed a different distance from one end of said tubular member than the free end portions on immediately transversely adjacent fins in the other said rows.
