Indeed it isn't.


All I was saying is that comparing (a) jointing an edge of a board
with a jointer (against the reference bed of the jointer) isn't
at all similar to freehand ripping on a tablesaw (i..e without the fence).

You can make a

As I clearly stated in my original post, I agree that the jointer is not the
proper tool to use to create parallel edges.
