A file works quite well, although slowly. For even slower metal
removal, use various forms of scraper (think single tooth file). For
coarser work, use hammer and chisel. If you want power assist, use
various grinders.

For this job symmetry was the main requirement. I find it very hard to file
irregular-shaped bars to make them into cylinders.
I tried the "reverse lathe" method using a bench sander. However, the part
is quite small and fingers are definitely an issue. I tried chucking it but
the set up was suboptimal and I nearly killed the part outright. Stopped
just in time.

I just took apart a very old Sears cordless drill and will try again
tomorrow with a better chucking arrangement.
