I agree that working with a round-over bit is asking for trouble.
In a hardware store, I saw a drill grinder attachment which had a

I was thinking of installing this on a lathe if that's what it takes.

BTW, how did they use to get a nice head on a wooden base ball bat ?
I suppose that they had some sort of lathe which would hold the base
while they could sand the ends.
