Although not copying Norm's practice (which was done out of needs for him; mine wants), when I build things, especially smaller pieces, I tend to make more than just one unit. 2 step stools, 6 gift trays, 2 wine boxes, etc., for example. The first piece may be a test for machine set-ups or procedures if new techniques or skills are involved, but it usually ends up well as one of the finished pieces.
Norm used a lot of dadoes as well as biscuits. I wonder, if the Domino Joiner were available in his time, whether he would change how he tackled some of the tasks.
Oh btw, when I'm on the treadmill for exercise, my usual YouTube viewing is either Norm or songs from the 70s or 80s. The last NYW episode I watched is the roll-top (tambour) desk (pt. 2). Often, you may pick up a new point or refresh your memory of certain trick from re-watching a classic like the NYW.
