I'm reading this question maybe a little differently than Tim and Mark. I'm wondering if he's referring to decorative backstrip and whether it's inlaid or glued in between the two back halves. I glue mine in full thickness between the two halves of the back all in one step, then thickness everything at once. The other alternative is to route a channel in the joined back and glue in the inlay in the cavity. Either way works, it's just what you're used to doing.

As for the reinforcement strip on the inside of the back, I glue mine in after the back is braced and attached to the sides. Many, if not most, glue them in before the back braces are installed, again, either way works fine.
