If he mounts it off-center and moves his tool in and out (his cutting

Not possible. Remember, he's starting out with a 3"x3" square timber. To get a
3" radius quarter-round out of that on a lathe, you'd have to mount the lathe
centers right at one of the corners.

It is not impossible.

Yes, it is.

You're obviously in an argumentative mood.
Impossible means that it cannot be done.
This is not one of those situations.

Like Derby said, you just have to synchronize
the in and out feed with the rotation. *Effecting this is left as an
exercise for the reader.

That's not sufficient. Go back and re-read what I wrote about where the lathe
centers have to be.

Fine, I did, and there was nothing there that I missed the first time
around. You've made up your mind that something that isn't
impossible, is, and then you snapped your mind shut - case closed.

The center of rotation has to be centered on the lathe, but that
doesn't mean the workpiece has to have its center centered. There are
a number of ways to accomplish that as well.
