Henry,
Might you have meant a "boring head"?

I've done the same thing to make quill locking pins for my mill. The cutouts almost appear to be straight cut rather than an arc. But I was cutting a larger radius.....

Math isn't my strong point  so don't confuse me with facts Henry. 
I just thought your cutouts would have had a wider arc than they do at that size radius. Which just goes to prove - "Be cool, stay in school!"

Wait, I went back and re read "boring head" so I thought WTF?
Then I read further and realized Henry edited his post.
That shouldn't be allowed, it makes the guy who catches the error look like an idiot (sorry Ed).

Editing should be allowed.
What I normally see on other sites is that if you edit a post before anyone has posted a reply, you can edit and nothing appears in the post to indicate it was edited. However, if you edit after a reply has been posted, the software places a footer that indicates the post has been edited, the person editing the post and a date/time stamp.
Some have a field when you edit where you can enter a reason for editing. A lot of people will place a note themselves when editing a post to let others know they edited it.
