42 and 46 flare tube 20 has first end 21 which is flared to retain first end plate 50 flare tube 20 opposing end 25 is inserted through end plate 50 and air cleaner collector section 32 a second end plate 50 is then placed on air cleaner collector section 32 and flare tube 20 is also inserted through second end plate 50 after flare tube 20 is inserted through both end plates 50 and the air cleaner collector section 32 flare tubes 20 are flared at ends 25 using an orbital riveter an orbital riveter is utilized to prevent buckling of flare tube 20 as it is flared by using an orbital riveter dimension consistency without tight tolerances of the flare tubes is possible this is possible as the orbital riveter continually spins while compressing flare tube 20 allowing equal pressure upon the entire flare tube this allows flare tubes 20 to be of slightly varying lengths as the riveter will flare the flare tube 20 until a desired compression of end plates 50 is obtained upon air cleaner collector section 32 the head for the orbital riveter can be obtained from bracker corporation of pittsburgh pa flare tubes 20 also add benefits to the air cleaner collector section and the method of manufacture flare tube 20 provides additional stiffness to the assembly by supporting the cell expansion tube through which it.
