First try deburring the edges. Then just sand down the hex shaft. You loose the fancy paint, but it fits!


As for the long shaft source, you could go with McMaster, which sells some .500 aluminum rod with the "ground and polished" finish. This will be the exact diameter, but doesn't have the keyway cut into it. You could then cut your own keyway, use a roll pin, or make some flat parts on the shaft, and use a set screw.
