I dunno Stuart. The shearing forces at work in the case of this motor flywheel would exceed, and has, the holding ability, even of a broken off tap left in the hole for a key. It appears they exceed most such curable liquids holding capacity. I think if I had to build up a shaft, the wire welder would get some use time to do the buildup, and then remachined to the correct size. But I have not noted the availability of a wire with hardness to match the original shaft, so the wear rate of such a repair will be faster. I just did exactly that earlier this past week on my 30+ yo Craftsman 38" rider. Welding up, and refinishing the shank of a pull rod for the deck to frame connection to fit the now worn hole it fits into. Who knows, it might last another 30 years, but it will not be witnessed by me unless I make it to 110 yo.
