Crown polishing?

That will work just fine , next best thing to having a lathe . Proper pilot fit in the bore is crucial with that tool.

I never said that. It may work fine but I trust the mill.

What does a crown cutter look like for a mill ? What advantage would it have over a properly turned crown produced on a lathe ? Thanks.

Depending on the style of crown in question, rebated, domed, stepped or dished etc. The machinist can use a variety of cutters to obtain the crown. I did a few on a mill which in fact has a lathe as one of its functions. A properly set up lathe will achieve the same results. For a rebated crown with a step we used three different cutters. I'm sure we are not far from each other with our methods.

I see now, same goal with a different approach . I had rifle barrels in mind and never thought past that . Thanks
