I plan to make cabinet doors out of some 4/4 lumber that I have . The panel doors will be 3/4" when finished. My question is: to what dimension should I plane and join the boards initially? Should I plane the lumber to the finished 3/4" and then glue up the panels? In the past I have left a little extra, i.e. 7/8", glued up the panels, and then planed them down to the finished 3/4" dimension. This made a real smooth joint where the pieces were glued together. But I wonder if I am wasting time planing twice?
What do you do?
