1. A method of making a metal to composite tube joint, including:
selecting an elongated metal inner sleeve constructed with an exterior flange formed with a first distally facing annular shoulder, and projecting distally to form a barrel of a selected length and then reduced-in diameter to form a first distally facing annular abutment shoulder and projecting further distally to form an inner shell having a radially outwardly facing bonding surface projecting distally and tapering conically inwardly;
selecting an elongated metal outer sleeve formed proximally with an annular abutment end and further formed with a collar of the selected length and constructed to fit over the barrel and increased in diameter to form an exterior, distally facing annular abutment shoulder and still further projecting distally to form an outer shell having a radially inwardly facing bonding surface tapering conically outwardly;
placing the outer sleeve over the inner sleeve with the collar fitted over the barrel and the abutment end abutted against the first distally facing annular shoulder to position the inner and outer shells in alignment to cause the respective radially inwardly facing bonding surface and radially outwardly facing bonding surface to form a distally expanding annulus;
selecting a composite tube constructed with an extremity formed with inner and outer surfaces shaped to be fitted in the annulus; and
applying a bond to the inner and outer surfaces of the extremity to bond to the respective radially inner and outer bonding surfaces.
