Hi all, Fortunately I don't need this repair done, but I am curious about how you would replace one of the main tubes in a nice lugged steel frame. Would you cut the damaged tube in half, heat the lug ends, then remove? Would the frame flex enough to insert the new tube, or do you need to disassemble the whole shootin' match? Obviously my mind was wandering while pretending it's is fun to ride my rollers. Thanks,Greg Brooks,Ridgetop,TN.
