I have a few old worn out shafts on my old Gravely tractors, instead of fighting the hardness of the weld even with a 7018 or 6013, has any one used the Loctite [FIX MASTER METAL REBUILD] that is supposed to be machinable with any good luck, it is supposed to be as strong as the original metal. I do have some spindles, slow speed shafts, shift linkage, brackets and such. Thanks! for any help. Vernon
