    i did this two seasons ago and quickly removed it. i just didnt like the way it pushed.. i quickly went to my local steel yard and bought a 1/4" 8" by 8' piece of t-3 steel.. (bulldozer steel) took it home, took the old one off, clamped the new one up, marked the holes, tourched them out, ground them clean and put new washers on to cover up the holes real nice... i havent even flipped my edge yet.. it'll probably last another two seasons before i have to do so...:drinkup:

    It could very likely crack off. Cutting edges are high carbon steel, and they don't weld as well as mild steel. The extra hardening that will occur from a quickly cooling weld will make a brittle spot that could crack off it you hit something, like a curb. Haven't tried it on cutting edge steel, but I have done it on cast iron, because I was curious, with very poor results.
