I have some wooden banister rods, the ends of which I want to grind

Is there an attachment for a power drill which will give me a half
sphere?
What is this tool called and where can I find one?
I was considering putting them on a lathe, but they are 10 feet long.
I don't want to take them off, as this is work, but maybe this might
be another solution.
Any suggestions, or better yet, links to pics or videos on how best to
do this?

Look for rounding dowel ends.
Here's one.http://www.binkyswoodworking.com/PegTip.php

the OP tries it and lets us know how it works out for him.
