PROPELLER SHAFT LINER ABSTRACT OF THE DISCLOSURE An improved propeller shaft liner of the type em- ployed to damp propeller shaft vibrations and apparatus for inserting such liner into the properller shaft. A tubular liner of paper is formed with a symmetrically disposed series of axially or helically extending groove-like indentations which provide the formed liner tube with a resiliently re- sisted radial and circumferential compressibility character- istic. This compressibility enables the liner to be inserted into a propeller shaft having an internal diameter less than the outer diameter of the liner, with the liner being sym- metrically deformed to engage the shaft in an accurately centered position to achieve a proper rotary balance of the shaft. Apparatus for inserting the tube into shaft is also disclosed.
