Finally I trim the rough edge off on the table saw. This makes the final edge parallel to the jointed edge and, if I have my saw set up properly, square to the two faces. I'll joint this edge in a bit just to be sure.
When I'm happy with it, I mark the joints to keep the alignment and run the sawn edges that are involved in glue joints through the jointer just to remove what little saw-swirl is there.
Because this plate is 15½" wide (or will be when I trim it) and my planer is 15" wide I'll glue up just one joint now, then surface plane the pieces to nearly the finished thickness (making one perfect joint) glue up the second joint, and smooth the whole panel with the wide drum sander.
I'm about out of time now so I'll pick this up again tomorrow. Thanks for popping in!
