How to center a piece of work on a rotary table?

[ScrapMetal]

Just an update to show how I'm doing on these.  There is still a lot more work to be done, a few edges to round off, and a lot of grinding/file work to make up for some sloppy cuts.



The "lump" on the end of the large radius is due to me not calibrating my rotary table to the mill before making the cut.   I little grinding here...



The pair of them - left and right front fender mounts for my shovelhead motorcycle build.  Here you can see one of the edges (the outer ones that end in a radius) that still need to be radiused.



This side just needs a little polishing.



Same here, a little grinding and polishing to get rid of the machining marks and it'll be good to go.

I'll take some more pics when I have them finished and installed.

Thanks,
