Process for repairing a cutting saw

Claim 1

A process for repairing a cutting saw used for trimming tree limbs from around power lines wherein the cutting head of the saw is powered by hydraulic fluid from rigid hydraulic fluid tubes extending through an elongated rigid non conductive sleeve that extends between an operator's handle and the cutting head of the saw, said tubes having tube end sections that become frequently damaged by vibration, which process comprises; disengaging the rigid sleeve from the power head of the saw and removing a fluid tube having a damaged area near one end, severing from the tube an end section of a determined length that includes a damaged area, and forming thereby a new fluid tube end, said severed end section and said new end having similar determined wall thicknesses and similar determined inside and outside diameters, reducing by about half the wall thickness of a substantial end portion of the new end, said reduction produced by one of the processes of the two processes including; removing material from the inside of the wall to increase the inside diameter; and removing material from the outside of the wall to reduce the outside diameter, providing a tubular tip having a body portion with a wall thickness, inside and outside diameters, and a length corresponding to the severed end section, and further having a reduced end portion of a length corresponding to the substantial reduced end portion of the new tube end, said reduced end portion of the tip being mated to the reduced end portion of the new tube end for male-female coupling relationship, interfitting and bonding the tubular tip to the new end portion of the tube to regenerate the damaged end section, and mounting the repaired fluid tube in the rigid sleeve and mounting the sleeve between the cutting head and operator's handle.
