Mount it up in a drill press, and if you have it, use some emery cloth, if you dont have any, and are strapped for time, use a very very fine toot file and lightly press the file against the turning shaft, and slide the file up and down, as to evenly take off material, and not lose the roundness of the shaft. WARNING: Be very very careful doing this with a file, if you press too hard, or if you dont evenly take off the material, your shaft will no longer be round, and probably useless.

Hope this helps,
