This is just a quick test to see how easy/effective it is to do a roundover operation on wood using an abrasive flap disk in an angle grinder in place of the more traditional hand plane or router.

I Started with some well seasoned White Oak:

Put a 80 Grit flap disk in a small angle grinder:

And then made several passes along the edge with the disk. Doing several passes along the corner at about 45 degrees to put a bevel on it, then furhter passes as sharper and shallower: angles to feather out the corners into a pencil round.

The result:

Which struck me as adequate for some bench seating slats (which was what promoted the discussion). A final sand by hand with a foam sanding block will take out any marks left by the disk.
