Abstract:
A method of increasing the wear resistance of a nose of a chain saw guide bar, the guide bar comprising two side rails forming a groove therebetween, each side rail having an edge surface, the side rails being curved at one end thereof to form a nose, the method comprising the steps of:A) providing a plate of wear resistant alloy having a thickness substantially equal to a width of each of the edge surfaces;B) making a series of identical cuts through the plate to form identically wave-shaped elements, each waveshaped element including at least two generally U-shaped strips joined end-to-end, each strip having a non-uniform width which is greater at a crest of the strip than at the ends thereof;C) separating the strips from one another; andD) welding each strip onto the edge surface of a respective side rail at the nose thereof, with the crest of the strip situated at a tip of the nose.
