Exactly. And that's why face jointing must precede planing.

but that's a different operation.


Yep. That's the operation that should be done *first*.

Yes. I saw your other post and gather I misinterpreted your initial
point...

In this case, all I was trying to do was to clarify that once the other
operation was done, it was done--unless, of course, the stock does move
significantly enough afterwards to destroy the previous work...

So, I guess the upshot is we're both right and have probably totally
p-o'ed the OP...
